Open CoreDataStack.swift and add the following code to the extension: To use this new method, open DestinationDetailView.swift. When you app is opened with such a link, then you can download the CKRecord and you will have the file in a CKAsset. Continue with Recommended Cookies. The class contains all the necessary methods and properties you need to interact with Core Data. After the share is accepted, NSPersistentCloudKitContainer automatically syncs all of the shared objects into the local store. Under the Schema section, select Indexes. This is the default database that data gets written to. You can think of the name as the primary key of the record in a simple database sense (names must be unique, for example). 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 based on the relationship they have to other objects. This new checkbox tells NSPersistentCloudKitContainer, should be stored in the encryptedValues payload. On Apple platforms, there are a number of ways we can share the data our applications create. That method works for documents saved to the current iCloud account. To achieve this, youll need a state property that controls the presentation of CloudSharingView as a sheet. For app developers, the situation was even worse. this new Allows Cloud Encryption checkbox. Here I've chosen four friends to share the photo with. Then, open the starter project. 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. Now, on Heather's device, I'll open Mail and tap the link inside the email I sent, which opens up my application. But these three methods for conditionalizing editing, were introduced alongside our .public database support, You can use these methods in your applications. Apps can support such use cases by moving user data to CloudKit and implementing a data sharing flow that includes features like share management and access control. After you have logged into the console, open CloudKit Database. designed to pair directly with UICloudSharingController. To understand these challenges a bit more clearly, we need to identify two crucial concepts for sharing. Once youre in this section, you need to specify the container you want to see. Also, the service itself must protect against a range of potential issues, such as unauthorized requests, conflicting changes, and the like. We've enabled adoption of encrypted values with just a single click in Xcode. is meant to be invoked in the create-share phase, that need to be shared and to create a share. Connect and share knowledge within a single location that is structured and easy to search. For each participant, NSPersistentCloudKitContainer manages objects in two CloudKit databases, the .private and the .shared database. Otherwise, use fetchShares(matching:) to see if you have objects matching the objectID in question. New in iOS 15 is acceptShareInvitations(from:into:completion:). To get the most out of this session, check out our previous videos on NSPersistentCloudKitContainer: "Using Core Data With CloudKit" from WWDC19 and "Sync a Core Data store with the CloudKit public database" from WWDC20. Heather, Jermaine, Percy, and Mary are all test accounts. In addition to this, you set databaseScope to .shared. Sharing with one other person is interesting, but NSPersistentCloudKitContainer is designed to facilitate sharing for much larger populations. Build and run. 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. 2 Reviews. catalogue of 50+ books and 4,000+ videos. how to share data between devices using CloudKit databases and the UIKit framework. This view contains the logic for your share button. CloudKit organizes data via a hierarchy of classes: CKContainer, CKDatabase, CKRecordZone, and CKRecord. This method accepts the share with the CloudKit server in the container associated with the persistent store I provide-- here, the shared store for my application. Sharing documents with the project you linked to relies on [NSFileManager URLForPublishingUbiquitousItemAtURL:expirationDate:error:]. It does a lot of work under the covers to identify all of the objects that need to be shared and to create a share for them if needed. CloudKit supports both structured and bulk data. No specific cutoff point is specified (a maximum of 1MB total is recommended for each CKRecord), but as a rule of thumb, just about anything that feels like an independent item (an image, a sound, a blob of text) rather than as a database field should probably be stored as a CKAsset. So how does NSPersistentCloudKitContainer know where to keep your records? Within a CKDatabase are CKRecordZones, and within zones CKRecords. 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. Join our team. If you attempt to select record type as CD_Destination and query records from here, you receive an error stating Field recordName isnt marked queryable. Jordan's line about intimate parties in The Great Gatsby? Let's get started with sharing. The only way to distinguish the private records versus shared records is to tap the detail and view the role in the participants list. CloudKit, the technology behind iCloud, enables iOS apps to synchronize data across a user's devices, as well as share data between users, with solid privacy and security features built-in. Please check your Internet connection and try again. Once the CloudKit schema is pushed to production, we can't change any of the field types. and the participants entry for Jermaine shows. NSPersistentCloudKitContainer also has to understand, how the concepts of owners and participants apply, Let's imagine I have a collection of people. When a user decides to share CloudKit data, a share link in the form of a URL is sent to the person with whom the data is to be shared. As always, I can't wait to see what you build with NSPersistentCloudKitContainer. Also, CloudKit provides a specific record type for large binary objects. wherever you need to customize your user interfaces. This snippet of code is part of a test case I wrote, to ensure that its table cells correctly indicate. 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). Learn SwiftUI and take your iOS Development to the Next LevelSwiftUI Essentials iOS 16 Edition book is now available in Print ($39.99) and eBook ($29.99) editions. to show that the post is part of a share. Instead of invoking methods on NSPersistentCloudKitContainer. 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. 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. The UICloudSharingController is a view controller that presents standard screens for adding and removing people from a CloudKit share record. more complicated code than if I chose not to support sharing. I had to decorate the post table cells to indicate which ones are shared. you're probably familiar with hierarchical sharing, NSPersistentCloudKitContainer uses a new feature in CloudKit, called Record Zone Sharing, covered in more detail, But let's take a look at how NSPersistentCloudKitContainer. With this code in place, navigate back to DestinationDetailView.swift to present CloudSharingView. Generally speaking, youll be working with an NSManagedObject from your view. Modern mobile application development requires a well thought-out plan for keeping user data in sync across various devices. That means we can't change our mind later and choose to encrypt fields that aren't already encrypted today in production. 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. CloudKit sharing allows records stored within a private CloudKit database to be shared with other app users at the discretion of the record owner. Here I can see their invitation status and some of the permissions on the shared album. When I tap Next, I can see my new album with the photo I shared. Add a destination. 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. Pauls been a developer for nearly three decades, working with many tech stacks but with a focus on Apple. Accepting share invitations and fetching the shared data. But our applications are usually designed, NSPersistentCloudKitContainer has to also help us make sense, of all of these objects so that we can build. I needed a way to ensure they all work correctly. Log in to your iCloud account on a real device. If you sent the invitation from a real device, that can be a simulator. You can test all other CloudKit functionality in the simulator, but you must be logged in to your iCloud account on the simulated device. with the CloudKit server in the container associated. Then, select the CloudKit checkbox to enable the feature. Last, head to the CloudKit Console so you can verify your data. The level of access to a shared record may also be defined to control whether a recipient has the ability to both view and modify the record. 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. 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 . 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. So that's how we use NSPersistentCloudKitContainer. This involves the creation of a CKFetchRecordsOperation object using the record ID contained within the CKShareMetadata object. To achieve this, youll implement fetchShares(matching:). Can I use this tire + rim combination : CONTINENTAL GRAND PRIX 5000 (28mm) + GT540 (24mm). Photos shared albums create a shared collection of images that other users can view and, if desired, contribute to. In my .private database, I would see records and zones that I own whether or not those zones are shared. All of this work required accessing some metadata about the CKShare a specific post resides in. 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. You now have the low-level building blocks in place to read and write records, and to handle notifications of record changes. Lets look now at a layer built on top of that to manage these operations in the context of a specific Note. Tapping this button removes a destination from your travel journal. When you create a destination, the data is being persisted via Core Data locally in your app. 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. Add the following method to your extension: With this code in place, you can determine if the destination is already shared and then take the proper action. What is the easiest way to share files between users with CloudKit? At the top level is CKContainer, which encapsulates a set of related CloudKit data. Here, youll add the code to accept the share. provided by NSPersistentCloudKitContainer. Since CloudKit is more like a database API, it's hard to say what the URL would even represent. Once set up, operations are passed to the CKDatabase object, where theyll be executed on a background thread. All the user needs to do at this point is enter the contact details for the intended share recipient and send the message. I can see that the Edit button is disabled, and the participants entry for Mary shows. Download the starter project by clicking the Download Materials button at the top or bottom of this tutorial. So I'll change the share options to mark the share as View Only. To begin the sharing process, add the following code to your persistentContainer below the // TODO: 1 comment: This code configures the shared database to store records shared with you. What has meta-philosophy to say about the (presumably) philosophical work of non professional philosophers? with their role, permissions, and acceptance state. On Mary's device, I'll accept the new share, and now I can see the new post. which tells it I'm ready to continue the sharing flow. Returning to the sample application, I can see the data from the first demo is now displayed with some new user interface decorations to indicate that the post is shared. Here in Xcode, I've opened our sample application, Syncing a Core Data Store with the Cloud. But how does all of this work? Download iOS 15.0+ iPadOS 15.0+ Xcode 13.4+ watchOS 8.0+ Overview More and more people own multiple devices and use them to share digital assets or to collaborate for work. Theres just one catch: This controller is a UIKit controller, and your app is SwiftUI. Change the permission to View only. We call them the owner and the participants. if the provided objectID is in sharedObjectIDs. . With the introduction of CloudKit sharing it is now possible for individual app users to share private database records with other users. Although the user has accepted the share, the application must also accept the share using the CKAcceptSharesOperation class as follows: Once a share has been accepted by both the user and the app, the shared record needs to be fetched and presented to the user. However, such conflicts can arise from other circumstances. Then, I set the BlockBasedProvider as the provider for the view controller, completing the injection. At what point of what we watch as the MCU movies the branching started? Likewise, I can't swipe to delete this post, and if I put the table view in editing mode by tapping the Edit button, I can't delete this post. For example, this user may have a private zone. Prior to the release of iOS 10, the only way to share CloudKit records between users was to store those records in a public database. Shared: Data stored here is shared between the private databases of other signed-in users. Open CoreDataStack.swift. Open CoreDataStack.swift. 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. However, CloudKit gives you the tools you need for this. 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. It's free to sign up and bid on jobs. 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. You could solve this by creating a CKRecord that contains a CKAsset which is the file that you want to share. The answer is, "Not much." share(_ managedObjects: to share: completion:) is a new method designed to pair directly with UICloudSharingController. Build and run. Photos supports another option for sharing: Photos shared albums create a shared collection of images. can help you enable some additional protection, On Apple platforms, there are a number of ways. If you've worked with sharing before, you're probably familiar with hierarchical sharing, where these records are associated with a root record called the share. my application can access data in both stores. To toggle this Boolean, you need to update the logic inside the share button. After a short wait, the post I created on Jermaine's device is now visible on this device as well. Theres also a share action that does nothing now. In theory, you needed only three steps. Thus, your AppDelegate should call application.registerForRemoteNotifications in didFinishLaunchingWithOptions and implement didReceiveRemoteNotification. Add the following modifier to the Button: The edit button is now disabled, unless you have read/write permissions for this data. and how to operate on records and objects. Were you able to figure it out? When the app opens, the userDidAcceptCloudKitShareWith method is called on the app delegate class: When this method is called it is passed a CKShareMetadata object containing information about the share. I've already modified it to support sharing posts with different iCloud users. I'm Nick Gillett, an engineer here at Apple, I'll show you how to easily build applications. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. We can see here that Jermaine is the owner. 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. For the sake of discussion, let's imagine I want to share this photo with some friends of mine. 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. When a notification comes in that a record has changed, CloudKitNoteDatabase will do the heavy lifting of fetching the changes from CloudKit. If necessary, you then pass the updated server record to CloudKit to write the new record. When the recipient taps on the share link, the app (if installed) will be launched and provided with the shared record information ready to be displayed. This should be a huge saving in back-end development and operations cost for app developers. if I change this line of code to use an existing share, NSPersistentCloudKitContainer will attempt to assign. to write all of these tests and structure the application. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Finally, I'll tap Send to send the email. Please enable JavaScript to enjoy the best experience. Looking for something specific? To demonstrate how sharing works with NSPersistentCloudKitContainer, I'm going to be using our sample application, Syncing a Core Data Store with the Cloud. just as they can in the zones that I own. The consent submitted will only be used for data processing originating from this website. NSPersistentCloudKitContainer automatically syncs. Thats it! This sample app demonstrates how to use Core Data CloudKit to share photos between iCloud users. Differentiating private data and shared data in SwiftUI. Please note all the code has explanatory comments at the key points. Then setup deeplinking for your app. In anticipation of this, split the save function into two steps. These values are stored in a new payload on CKRecord called encryptedValues, introduced in the "What's New in CloudKit" session. Naturally, this domain knowledge is reflected in the APIs we have built for NSPersistentCloudKitContainer. If I'm allowed to, I can add records that I own to any of those zones just as they can in the zones that I own. to test these decision points by injection. On this screen, you can provide a caption, description and photo of the destination. This means not only the owner but also the second user can modify the data shared with them. Amazing! Next, open DestinationDetailView.swift. depending on whether or not they are the owner of those zones. Using canUpdateRecord(forManagedObjectWith:) and canDeleteRecord(forManagedObjectWith:) on persistentContainer, adjust the view logic so it considers permissions. So I'll tap Mail and then enter the information for my friends. I left off the scaffolding for creating the sample data, but the test crafts a mixed set of managed objects that it identifies as shared or not shared by the presence of their objectID in this set. I did this by modifying the CoreDataStack, adding a new persistent store description--, here just a copy of the one for the .private store, Then, I set its CloudKit container options, to be configured to mirror persistent stores, I adopted a new method on NSPersistentCloudKitContainer, share(_ managedObjects: to share: completion:). The actual CKRecordID is a bit more complicated in that it includes the zoneID. CloudSharingView conforms to the protocol UIViewControllerRepresentable and wraps the UIKit UICloudSharingController so you can use it in SwiftUI. share NSPersistentCloudKitContainer between app and extension, Core Data sharing with CloudKit: Unable to Accept Share. Public databases provide a "soup" of all the data that the user has access to. However, Apple strongly urges developers to use the operations rather than the convenience methods. There's a lot of new API to learn about. Navigate to AppDelegate.swift and youll see SceneDelegate is empty. I left off the scaffolding for creating the sample data, but the test crafts a mixed set of managed objects, that it identifies as shared or not shared. Each of these is mirrored to a persistent store. that controls who can access these zones that I own. CloudKit provides much more functionality on top of this, especially for sophisticated data models, public sharing, advanced user notification features, and more. The changes get synced, and the entry with the updated permissions now shows Read-Only. The next step is to create the container your data will live in. Photos implements a system control here in the lower left that allows me to call up an Action sheet. In my .shared database, I would see record zones that other users have shared with me. 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. This is a thorny problem with many gotchas and pitfalls, but users expect the feature and expect it to work well. Should I include the MIT licence of a library which I use from a CDN? More importantly, you have a foundation for adding more advanced CloudKit functionality. Figure 48 2 shows an example share options settings screen: Once a method of communication has been selected by the user from the cloud sharing controller, the completion handler assigned to the controller will be called. At this point, if you shared the invitation via text message, open Messages and tap the invitation. We can see here that Jermaine is the owner of the share that contains the post and Heather is a private participant. In many cases, it can infer where records belong based on the relationship they have to other objects. The solution is in CloudSharingController.swift. CloudKit sharing allows records stored within a private CloudKit database to be shared with other app users at the discretion of the record owner. NSPersistentCloudKitContainer includes a number of API methods to align with each of these concerns. It brings together a huge amount of domain knowledge. For example, I might need to know whether or not an object is shared. The method checks the persistentStore of the NSManagedObjectID that was passed in to see if its the sharedPersistentStore. You could use the recordId for this. Go to the first device you created the share from, because you need to be the Owner to access the Share Options. Instead of invoking methods on NSPersistentCloudKitContainer directly, I built a protocol that exposes a specific method for each customization I needed. Sync user data between multiple apps from the same developer. a specific method for each customization I needed. 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. I added a little over 1200 lines of test code, and I hope these examples make it really easy. An example of data being processed may be a unique identifier stored in a cookie. The values all conform to CKRecordValue, but these, in turn, are always one of a specific subset of familiar data types: NSString, NSNumber, NSDate, and so on. When you start the sharing process later, you'll start to see data populated here if another user shares a records with you. The SharingProvider protocol makes it easy to test these decision points by injection. It: Now, open DestinationDetailView.swift. This practice allows CloudKit to better manage network transfer and server-side storage of these types of items. Finally, I'll tap Send to send the email. From here, you store a reference to CKShare that returns from the share method. Have a question? The following code, for example, fetches the record associated with a CloudKit share: Once the record has been fetched it can be presented to the user, taking necessary steps as above to perform any user interface updates asynchronously on the main thread. 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. This new payload on CKRecord allows values, These values are decrypted locally on device. And exactly how much did I have to change in the sample application? Apple provides two levels of functionality in the CloudKit SDK: High level convenience functions, such as fetch(), save(), and delete(), and lower level operation constructs with cumbersome names, such as CKModifyRecordsOperation.
