Its fair to say iCloud got off to a bit of a rocky start. These silent pushes happen entirely without user visibility or interaction, and as a result, dont require the user to enable push notification for your app, saving you many potential user-experience headaches as an app developer. The convenience API is much more accessible, while the operation approach can be a bit intimidating. CloudKit automatically configures every CloudKit-enabled app out of the box to have a public CKDatabase (all users of the app can see everything) and a private CKDatabase (each user sees only their own data). To understand these challenges a bit more clearly, we need to identify two crucial concepts for sharing. Now, youll resolve this error. If I select the location attribute, I can see its configuration in the data model inspector on the right. Owners create and share objects with a set of participants. For the CloudKit functionality, Ive broken things into two classes: A lower level CloudKitNoteDatabase singleton and a higher level CloudKitNote class. Tapping this button removes a destination from your travel journal. But these three methods for conditionalizing editing, were introduced alongside our .public database support, You can use these methods in your applications. With this code in place, navigate back to DestinationDetailView.swift to present CloudSharingView. These days, modern mobile application development requires a well thought-out plan for keeping user data in sync across various devices. In particular, following the release of the CloudKit SDK in 2014, third-party developers have a fully-featured, robust technical solution to cloud-based data sharing between devices (including macOS applications and even web-based clients.). To achieve this, iOS 15 introduces share(_:to:). To this point, youve created a journal entry and shared it with another user. The version held by the server at the time you submitted the request. Each participant will also have their own collection of devices. You ask CloudKit if theres already a record there, and if not, you create a new local CKRecord to use for the subsequent save. Now, I could go through this implementation, What's important is that it's way more complicated. Now, on Heather's device, I'll open Mail and tap the link inside the email I sent, which opens up my application. Please enable JavaScript to enjoy the best experience. Once youve completed these steps, the data in your app then automagically sync with iCloud. After you have logged into the console, open CloudKit Database. It: Now, open DestinationDetailView.swift. Participants can have different roles and permissions that constrain how they can act on a particular set of objects, which brings us to the second key concept: how NSPersistentCloudKitContainer and CloudKit structure these shared objects. Open CoreDataStack.swift. In addition to sending a share link, the app must also be adapted to accept a share and fetch the record for the shared cloud database. For iOS and macOS, Apple provides a robust toolkit, called CloudKit API, which allows developers targeting Apple platforms to solve this synchronization problem. if the provided objectID is in sharedObjectIDs. If I tap on it, I can also see the participants displayed at the bottom of the detail view controller with their role, permissions, and acceptance state. Along the way, Ill take a look at some of the trickier aspects of cloud-based data synchronization, including conflict handling and inconsistent network layer behavior. Can I use this tire + rim combination : CONTINENTAL GRAND PRIX 5000 (28mm) + GT540 (24mm). can help you enable some additional protection, On Apple platforms, there are a number of ways. and operate on the objects I share with them. I and, if allowed, other participants can add. Not the answer you're looking for? You can think of the name as the primary key of the record in a simple database sense (names must be unique, for example). I've had to make a number of changes to the user interface. In addition to this, you set databaseScope to .shared. Sync user data between multiple apps from the same developer. See the solution below: [spoiler title=Solution 1] You see a travel journal screen with an empty state message and a button. The consent submitted will only be used for data processing originating from this website. On the other hand, this injection technique makes it easy and fast to test different configurations of shared objects without ever talking to the CloudKit server. Heather, Jermaine, Percy, and Mary are all test accounts. more complicated code than if I chose not to support sharing. to call the contains method of the set I created. fetchShares(matching objectIDs:) is new in iOS 15 and allows me to get the CKShare for a specific post. When the user taps the link that was shared earlier and accepts the invitation, the delegate calls this method and launches the app. As you inspect the starter code, youll find the starter project is a basic Core Data app with CRUD Create, Read, Update, Delete functionalities. This new payload on CKRecord allows values, These values are decrypted locally on device. Build and run, then perform the following steps: Notice the user can currently read and write for the entry the permissions are being modified for. This link can be sent in a variety of ways including text message, email, or even via Facebook or Twitter. So that's how we use NSPersistentCloudKitContainer to combine the .private and .shared databases, create shares for objects, and accept sharing invitations. At this point, if you shared the invitation via text message, open Messages and tap the invitation. directly to specific call sites in my application. A user of an app could, for example, make one or more records accessible to other users so that they can view and, optionally, modify the record. At the top level is CKContainer, which encapsulates a set of related CloudKit data. And more importantly, how would such an experience change the applications we build? The most amazing part is that because your data is now synced in iCloud, you can run your app on a completely different device thats signed in to the same iCloud account and see all your data! Figure 48 3, for example, shows a share link loaded into the Mail app ready to be sent: When a user receives a share link and selects it, a dialog will appear providing the option to accept the share and open it in the corresponding app. This involves the creation of a CKFetchRecordsOperation object using the record ID contained within the CKShareMetadata object. Instead of invoking methods on NSPersistentCloudKitContainer. Is something like this (or even better) available with the new CloudKit? Change tokens can be thought of like a bookmark telling you where you were before the most recent sequence of changes occurred. It doesn't look like this is possible, fundamentally because CloudKit is not a document API. I'm Nick Gillett, an engineer here at Apple on the Core Data team. When a record is shared, a share link is sent to the recipient user in the form of a URL. Open CoreDataStack.swift. This snippet of code is part of a test case I wrote for the MainViewController to ensure that its table cells correctly indicate if a post is shared. Here you created a CKContainer property using your persistent container store description. I'll open the CoreDataCloudKitDemo managed object model, and there's a specific property on the post entity I want to show you called location. Then setup deeplinking for your app. Theres one minor bug with your app at the moment. Does Cast a Spell make you a spellcaster? First off, you need to make sure youre starting from a valid CKRecord. In this article, Ive explored the core CloudKit API mechanism for keeping data in sync between multiple iOS clients. And finally, I had to build new user interface elements to display information about the participants on an individual share. For example, a user may have made edits on one device while in airplane mode, and then absent-mindedly made different edits on another device before turning airplane mode off on the first device. A general guideline is to use com.company_name.bundle_identifier. You would need a unique identifier for that CKRecord. This is the default database that data gets written to. Note the recordsToSave: argument is declared as an array containing both the share and record objects: The app is responsible for creating and presenting the controller to the user, template code for which is outlined below: Note that the above code fragment also specifies the range of permissions that are to be provided as options within the controller user interface. Go to the first device you created the share from, because you need to be the Owner to access the Share Options. Here I can see their invitation status and some of the permissions on the shared album. to store the objects an application creates. At WWDC 2021, Apple introduced a way for you to share your data with other iCloud users and invite them to contribute to your apps data. Since this is a first example of using an operation, here are a couple of general observations: First, all CloudKit operations have custom completion closures (and many have intermediate closures, depending on the operation). How might we build an experience like this? This is a thorny problem with many gotchas and pitfalls, but users expect the feature, and expect it to work well. Two separate iCloud accounts To initiate the sharing process. whether or not to convert the title of a post. Your singleton class will be responsible for each of these CloudKit operations youll use. Since CloudKit is deeply tied to Apples operating systems and devices, its not suitable for applications that require a broader range of device support, such as Android or Windows clients. After the share is accepted, NSPersistentCloudKitContainer automatically syncs all of the shared objects into the local store. I adopted a new method on NSPersistentCloudKitContainer to create the share. So that's how we use NSPersistentCloudKitContainer. Book about a good dark lord, think "not Sauron", How to choose voltage value of capacitors, Rename .gz files according to names in separate txt-file. You could solve this by creating a CKRecord that contains a CKAsset which is the file that you want to share. CloudKit sharing involves the creation of CKShare objects initialized with the record to be shared. Have a question? Add the following modifier to the Button: With this code in place, only users with the proper permissions can perform actions like editing or deleting. to add specific logic to my application code. So I'll tap Mail and then enter the information for my friends. This snippet of code is part of a test case I wrote, to ensure that its table cells correctly indicate. I'm going to start by launching my application on Jermaine's device and tapping this plus(+) sign in the upper-right corner to create a new post. Here I've chosen four friends to share the photo with. CloudKit app require a few items to be enabled on the Capabilities Pane of the Xcode Target: iCloud (naturally), including the CloudKit checkbox, Push Notifications, and Background Modes (specifically, remote notifications). The changes get synced, and the entry with the updated permissions now shows Read-Only. So how does NSPersistentCloudKitContainer know where to keep your records? Why was the nose gear of Concorde located so far aft? Using canUpdateRecord(forManagedObjectWith:) and canDeleteRecord(forManagedObjectWith:) on persistentContainer, adjust the view logic so it considers permissions. and some of the permissions on the shared album. In Record Zone Sharing, shared CKRecords are contained inside a shared CKRecordZone. before they are uploaded to the CloudKit server. For example, I might need to know whether or not an object is shared. Once youre in this section, you need to specify the container you want to see. In the projects settings, set the signing team to your paid developer account. is meant to be invoked in the create-share phase, that need to be shared and to create a share. But how does all of this work? On Mary's device, I'll accept the new share, and now I can see the new post. Using a single managed object context, my application can access data in both stores. The prior version of the record you tried to save. I'll open Mail and tap the link inside the email I sent, And exactly how much did I have to change, Sharing is by far the most complicated feature. It is capable of handling large file transfers seamlessly. With sharing, NSPersistentCloudKitContainer will also create shared zones for me with a CKShare record that controls who can access these zones that I own. On Jermaine's device now, I'll accept the new share. Finally, I invoke UICloudSharingController's completion block with the results provided by NSPersistentCloudKitContainer, which tells it I'm ready to continue the sharing flow. CloudKit sharing allows records stored within a private CloudKit database to be shared with other app users at the discretion of the record owner. With a free Kodeco account you can download source code, track your progress, into the sharingProvider the MainViewController uses. Update the selected zone from defaultZone to the automatically generated com.apple.coredata.cloudkit.zone. Build apps that share data through CloudKit and Core Data Learn how to easily build apps that share data between multiple iCloud users with NSPersistentCloudKitContainer. here, the shared store for my application. and how to operate on records and objects. For more information, check Apples video on Build apps that share data through CloudKit and Core Data. Basic CloudKit Setup CloudKit organizes data via a hierarchy of classes: CKContainer, CKDatabase, CKRecordZone, and CKRecord. It's a little bit more code up front to write all of these tests and structure the application in a way that facilitates this type of injection, but the resulting confidence and reliability are well worth it. Let's see that in action. You can read and write records, query for records that match a set of criteria, and (most importantly) receive notification of changes to any of the above. Also, a CloudKit record may only be shared if it is stored in a private database and is a member of a record zone other than the default zone. At least one real device To send and accept share invitation(s). and the participants entry for Jermaine shows. I've already saved Heather and Mary in my address book, so they're easy to find. But first, a quick discussion of CloudKit Errors. To learn more, see our tips on writing great answers. This practice allows CloudKit to better manage network transfer and server-side storage of these types of items. Second, enable the iCloud capability in your app. Tap the entry you want to update the permissions for. CloudKit: For managing structured data and sharing data among users. This framework ( https://github.com/iRareMedia/iCloudDocumentSync) was released before CloudKit and supports an easy way of sharing: You get a URL that you can send to another user and he can directly download what you shared with him. For example, if you want to extend this app to handle multiple Notes rather than just one, you could do so more readily (and with higher resulting performance) than if youd just used Apples convenience APIs. Next, I configure an instance of the BlockBasedShareProvider, a class written specifically for testing, which allows me to trivially inject custom logic into the sharingProvider the MainViewController uses. That can enable some interesting cross-application workflows. See the solution below: [spoiler title=Solution 2] CloudKit provides you ready to use data sharing API that allows you to implement collaborative features of your app without much effort. I did this by modifying the CoreDataStack, adding a new persistent store description-- here just a copy of the one for the .private store with a different URL. I had to build new user interface elements, to display information about the participants, All of this work required accessing some metadata. But in my application, I took a slightly different approach. Once set up, operations are passed to the CKDatabase object, where theyll be executed on a background thread. How might I do that? Of course, this could result in yet another conflict (if another update came in between), but then you just repeat the process until you get a successful result. Now, I could go through this implementation line by line, but that's not what's important here. What's important is that it's way more complicated than I can easily exercise every time I want to verify a change to the table view, and trying to do so would add a lot of friction to the development process. We've enabled adoption of encrypted values. They build on Apples notification infrastructure to allow various clients to get push notifications when certain CloudKit changes occur. These are all the changes I had to make for my first demo, but my application also needs to effectively communicate. Launching the CI/CD and R Collectives and community editing features for How to share Core Data between multiple users? that other users can view and, if desired, contribute to. Click Add Basic Index. CloudKit organizes data via a hierarchy of classes: CKContainer, CKDatabase, CKRecordZone, and CKRecord. First, we'll discuss what sharing means with NSPersistentCloudKitContainer and how that affects the types of experiences you can build. It rejects specific requests with enough error context in the response to allow each client to make a local, enlightened decision about how to resolve the conflict. I might need to know whether or not an object is shared. In Core Data, we think of our objects in terms of NSManagedObject. It accepts the share and adds the necessary metadata into the sharedPersistentStore. A participant is any other iCloud account that is allowed to operate on those objects in some way. I'll tap the Action button to bring up the sharing controller, but this time, I want the share to be read-only so that the participants can't edit or modify the contents of the share. It is important to be aware that when a share recipient accepts a share they are actually receiving a reference to the original record in the owners private database. For your Note app, you can use the default container. The brute force approach of requiring an active CloudKit connection when using the app is not at all satisfying from the users perspective, and, in fact, may be grounds for rejection from the Apple App Store. Here I used isShared to decide whether or not to convert the title of a post to an attributed string and prefix it with the person.circle symbol to show that the post is part of a share. Can users edit their own private data in CloudKit. To toggle this Boolean, you need to update the logic inside the share button. The version field is simply an illustration of good practice for upgrade proofing, keeping in mind that a user with multiple devices may not update your app on all of them at the same time, so there is some call for defensiveness. Notice the role and permission for each user. that constrain how they can act on a particular set of objects. Depending on the context, you may wish to assign a higher qualityOfService and handle these situations yourself. For our purposes, a single view application containing a UITextView with the ViewController as its delegate will suffice. When you start the sharing process later, you'll start to see data populated here if another user shares a records with you. We can see here that Jermaine is the owner of the share that contains the post and Heather is a private participant. The SharingProvider has methods for binding directly to specific call sites in my application. Connect and share knowledge within a single location that is structured and easy to search. What is the easiest way to share files between users with CloudKit? Hiring? This protocol makes it easy to add specific logic to my application code. CloudKit supports both structured and bulk data. of shared objects without ever talking to the CloudKit server. than the simple injection I used in the test. Let's look at that change in a bit more detail. Navigate to AppDelegate.swift and youll see SceneDelegate is empty. An object that represents activity in a persistent CloudKit container. Kodeco requires JavaScript. If a match returns, this object is already shared. The following code, for example, creates a CKShare object containing the record to be shared and configured for read-only access: Once the share has been created, it is saved to the private database using a CKModifyRecordsOperation object. At the moment, when you launch the app, entries in your journal all look the same. But you can also tell share(_ managedObjects: to share: completion:) to store objects in a specific shared zone by passing it a non-nil CKShare. Learn iOS, Swift, Android, Kotlin, Flutter and Dart development and unlock our massive Add the following code as one of the modifiers for your List: This code uses getShare(_:) and retrieves CKShare. Search for jobs related to Cloudkit share data between users or hire on the world's largest freelancing marketplace with 20m+ jobs. Rather than relying on individual notifications to give you detailed knowledge of what change an individual notification represents, you use a notification to simply indicate that something has changed, and then you can ask CloudKit whats changed since the last time you asked. The UICloudSharingController is a view controller that presents standard screens for adding and removing people from a CloudKit share record. The owner is the iCloud account that actually owns an object. Page - Sharing data between User Controls without access to the Page class - Accessing data between user controls WPF - Passing data between user controls in wpf - Pass data between parent child user controls . Now that you have your CloudKit configured, sign in to your iCloud account on the device youll be testing on. Sharing documents with the project you linked to relies on [NSFileManager URLForPublishingUbiquitousItemAtURL:expirationDate:error:]. Here I'm setting the isSharedBlock to call the contains method of the set I created. Otherwise, use fetchShares(matching:) to see if you have objects matching the objectID in question. Enter a topic above and jump straight to the good stuff. To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. Finally, one of the most important aspects of any operation is the qualityOfService value. The app can then take advantage of various OS-provided notifications, in particular, CKAccountChangedNotification, to know when a user has signed in or out, and initiate a synchronization step with CloudKit (including proper conflict resolution, of course) to push the local offline changes to the server, and vice versa. Open CoreDataStack.swift. I've configured it to be an optional Transformable attribute and checked this new Allows Cloud Encryption checkbox. Apple has been adding data sharing into many of its first-party apps, including: Files Reminders Notes Calendar Photos Activities Find My Maps Music Health Then just create a deplink that includes that unique identifier. Tap the Add Destination button. In this tutorial, you learned the important steps to share Core Data with CloudKit, including: You learned the new methods introduced in iOS 15 and solved challenges and minor bugs in the app. However, you dont have any metadata about the share. Discover how to create informative experiences around shared data and learn about the CloudKit technologies that support these features in Core Data. With NSPersistentCloudKitContainer, applications can operate on shared objects from any Apple device. Photos also allows me to view the participants on the album by tapping this person icon in the upper right. NSPersistentCloudKitContainer turns those managed objects. This is your Destination entity in Core Data. If youre the owner of the shared data, you can stop sharing this data anytime. which tells it I'm ready to continue the sharing flow. Should I include the MIT licence of a library which I use from a CDN? In my .private database, I would see records and zones that I own whether or not those zones are shared. Build and run. With this code in place, build and run on your second device. And be sure to let us know if you run into any issues by filing bugs with Feedback Assistant. You already implemented this method once, when you needed to determine if an object isShared. Download the starter project by clicking the Download Materials button at the top or bottom of this tutorial. To dig deeper into CloudKit, I strongly recommend taking the time to view the various CloudKit presentations from each of the last few WWDCs and follow along with the examples they provide. To demonstrate how sharing works with NSPersistentCloudKitContainer, I'm going to be using our sample application, Syncing a Core Data Store with the Cloud. Each of these is mirrored to a persistent store in my application, one using the .private database scope and the other using the .shared database scope. For these reasons, I am using the operations in these code examples. I get a Error Fetching Record error, even if I copy and paste it in. If its not shared, create the share from the destination object. I've already saved Heather and Mary in my address book. Modern mobile application development requires a well thought-out plan for keeping user data in sync across various devices. this new Allows Cloud Encryption checkbox. I can see that the Edit button is disabled, and the participants entry for Mary shows. Note that the same code will work for macOS clients as well, with slight adjustments for differences in how notifications work on that platform. We call them the owner and the participants. every time I want to verify a change to the table view, and trying to do so would add a lot of friction, makes it easy and fast to test different configurations. At what point of what we watch as the MCU movies the branching started? [/spoiler]. to display more information in my user interface. A record? If I tap on it, I can see that the Edit button is disabled and the participants entry for Jermaine shows that he is a Read-Only participant on the share. The CKShare object may also be configured with title and icon information to be included in the share link message. Now that youve sent an invitation to your second user, you need to set the app to accept the invitation and add the data into the shared store. I'm going to be using our sample application. Join our team. It brings together a huge amount of domain knowledge. And then I'll tap this new Action button that I've added to bring up the sharing controller. they would see my two zones that I share with them, and any other zones they are a participant on, So how does NSPersistentCloudKitContainer. by tapping this person icon in the upper right. At the top level is CKContainer, which encapsulates a set of related CloudKit data. Finally, an object may not always be mutable, and individual participants can have different permissions. This means not only the owner but also the second user can modify the data shared with them. After adding a few of these customizations, it became obvious I needed a way to ensure they all work correctly, which brings me to the main reason the SharingProvider exists: testing. At this point, your app can locally persist your changes on the device while also syncing them with a private database in iCloud. Also, CloudKit provides a specific record type for large binary objects. Get the most out of CloudKit Sharing Discover how apps can use CloudKit to share records with others. Over time, however, Apple has addressed these issues. In this example, theres just the one record, but for future expandability, this is a great potential performance benefit. Asking for help, clarification, or responding to other answers. Youll need to ensure that you have set a unique bundle identifier at this point.
