Now, you should see a Button with Label("Delete", systemImage: "trash"). Note that the same code will work for macOS clients as well, with slight adjustments for differences in how notifications work on that platform. Tap the entry you want to update the permissions for. With sharing, NSPersistentCloudKitContainer will also create shared zones for me with a CKShare record that controls who can access these zones that I own. It is capable of handling large file transfers seamlessly. 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. - Accepting a shared note will now move it to the top level of your notes folder - Fixed a bug where clicking on the month name on macOS shifted the calendar weeks - Improved website titles when pasting a web link in NotePlan - iCloud Drive sync is now hidden as a sync option for new users since Cloudkit provides a better sync experience Within this container, youre going to use the private database (because you want the users note to be seen only by that user) and within the private database, youre going to use a custom record zone, which enables notification of specific record changes. Once you add the destination, tap the destination to view DestinationDetailView. if I change this line of code to use an existing share, NSPersistentCloudKitContainer will attempt to assign. And exactly how much did I have to change in the sample application? These can be normal push notifications familiar to iOS users (such as sound, banner, or badge), or in CloudKit, they can be a special class of notification called silent pushes. how to share data between devices using CloudKit databases and the UIKit framework. Open CoreDataStack.swift. With this code in place, navigate back to DestinationDetailView.swift to present CloudSharingView. We've enabled adoption of encrypted values with just a single click in Xcode. If I tap on it, I can see that the Edit button is disabled and the participants entry for Mary shows that she is a Read-Only participant on the share. 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. 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. Sharing is by far the most complicated feature we have built in to NSPersistentCloudKitContainer. Add a destination. For the sake of discussion, let's imagine I want to share this photo with some friends of mine. 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. Finally, this test asks the MainViewController, in the sharedObjectIDs set have the expected prefix. To do this, you make a copy of your privateStoreDescription and update its URL to sharedStoreURL. CloudKit operations provide superior control over the details of how CloudKit does its work and, perhaps more importantly, really force the developer to think carefully about network behaviors central to everything CloudKit does. for you to build tests in your own applications. Build and run. that is allowed to operate on those objects in some way. The consent submitted will only be used for data processing originating from this website. Each of these participants will be able to access and operate on the objects I share with them. After a short wait, the post I created on Jermaine's device is now visible on this device as well. rev2023.3.1.43269. Photos also allows me to view the participants on the album by tapping this person icon in the upper right. It's free to sign up and bid on jobs. NSPersistentCloudKitContainer automatically syncs. Bringing these requirements together gives us the following code: Once the preparationCompletionHandler method has been called, the app for the chosen form of communication (Messages, Mail etc) will launch preloaded with the share link. I had to decorate the post table cells to indicate which ones are shared. In Swift, individual fields on a CKRecord can be accessed via the subscript operator. There are two ways to share data via CloudKit: record sharing and zone sharing. As always, I can't wait to see what you build with NSPersistentCloudKitContainer. Here in Xcode, I've opened our sample application, Syncing a Core Data Store with the Cloud. This is a cute trick in Swift that allows me to simply check if the provided objectID is in sharedObjectIDs. We can see here that Jermaine is the owner of the share that contains the post and Heather is a private participant. to test these decision points by injection. Thanks for contributing an answer to Stack Overflow! On Jermaine's device now, I'll accept the new share. Each participant will also have their own collection of devices. I've already saved Heather and Mary in my address book, so they're easy to find. Here I'm setting the isSharedBlock to call the contains method of the set I created. provided by NSPersistentCloudKitContainer. NSPersistentCloudKitContainer includes a number of API methods to align with each of these concerns. When the dialog asks whether you would like to open the invitation, choose Open. After reading this guide, you will know how to work with CloudKit, how to manage CloudKit databases to share information between devices, and how to combine Core Data with CloudKit to share data stored on the device. However, CloudKit gives you the tools you need for this. Sign in to your Apple ID. of shared objects without ever talking to the CloudKit server. 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. by tapping the Edit button, I can't delete this post. to instantiate an instance of UICloudSharingController. 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. Depending on the context, you may wish to assign a higher qualityOfService and handle these situations yourself. CloudKit - Share Files between Users via a URL, https://github.com/iRareMedia/iCloudDocumentSync, https://github.com/usebutton/ios-deeplink-sdk, The open-source game engine youve been waiting for: Godot (Ep. To understand these challenges a bit more clearly, we need to identify two crucial concepts for sharing. create shares for objects, and accept sharing invitations. Sharing CKAssets between users with CloudKit? 2 Answers Sorted by: 8 In iOS 10 / macOS 10.12, it is now possible to share hierarchies of records in a user's private database with other users. Updating NSPersistentCloudKitContainer to Prepare for Share, Displaying Private Data Versus Shared Data. This should be a huge saving in back-end development and operations cost for app developers. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. 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. I've had to make a number of changes to the user interface. directly to specific call sites in my application. For example, I might need to know whether or not an object is shared. 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). CloudKit supports both structured and bulk data. I had to build new user interface elements, to display information about the participants, All of this work required accessing some metadata. For example, this user may have a private zone and a shared zone that they own in their .private database. So be sure to use NSPersistentCloudKitContainer's initializeSchema method to ensure that all your fields are present and correctly typed before deploying your schema to production. But let's take a look at how NSPersistentCloudKitContainer uses Record Zone Sharing to share managed objects. To change the permissions and access to this data, Apple has done all the heavy lifting for you. 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. Then, select the CloudKit checkbox to enable the feature. more complicated code than if I chose not to support sharing. Finally, I'll tap Send to send the email. Let's imagine I have a collection of people I want to share with. I and, if allowed, other participants can add. From this screen, you can take a few actions. Once youve completed that task, set showShareSheet, which presents CloudSharingView, to true. Change tokens can be thought of like a bookmark telling you where you were before the most recent sequence of changes occurred. Now, I could go through this implementation line by line, but that's not what's important here. At the top level is CKContainer, which encapsulates a set of related CloudKit data. Lets look now at a layer built on top of that to manage these operations in the context of a specific Note. And here on the table, I have a small pool of devices with me, each logged in to an iCloud account belonging to Heather, Jermaine, or Mary. I adopted a new method on NSPersistentCloudKitContainer to create the share. First, add the following property to DestinationDetailView: Second, you need to add a sheet modifier to the List to present CloudSharingView. The app designer is always in the best position to define rules for these situations, which can include everything from context-aware automatic merging to user-directed resolution instructions. in a way that facilitates this type of injection. For these reasons, I am using the operations in these code examples. 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. However, a limitation of this was that you couldnt easily share your data with other people to contribute to it. Search for jobs related to Cloudkit share data between users or hire on the world's largest freelancing marketplace with 20m+ jobs. Change the permission to View only. These options are accessed and modified by tapping the Share Options item at the bottom of the cloud sharing controller view. here, the shared store for my application. 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. Navigate to AppDelegate.swift and youll see SceneDelegate is empty. informative user interfaces for our users. It's called the SharingProvider. Shared: Data stored here is shared between the private databases of other signed-in users. If I tap on it, I can also see the participants, displayed at the bottom of the detail view controller. The simple act of writing a record to the database is straightforward enough, but in my example, with multiple clients, this is where youll face the potential issue of handling a conflict when multiple clients attempt to write to the server concurrently. This class is initialized with the root CKRecord instance that is to be shared with other users together with the permission setting. 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. Using a single managed object context, my application can access data in both stores. To complete the demo, I had to make two other changes. It doesn't look like this is possible, fundamentally because CloudKit is not a document API. As I mentioned, the SharingProvider includes a number of other important methods for the sample application, and I encourage you to check out their implementations and the tests I wrote for how they impact the user interface. We call them the owner and the participants. Photos implements a system control here in the lower left that allows me to call up an Action sheet. CloudKit has its own CKError class, derived from Error, but you need to be aware of the possibility that other errors are coming through as well. New in iOS 15 is acceptShareInvitations(from:into:completion:). Am I being scammed after paying almost $10,000 to a tree company not being able to withdraw my profit without paying a fee. they would see my two zones that I share with them, and any other zones they are a participant on, So how does NSPersistentCloudKitContainer. Customizations like this necessarily require more complicated code than if I chose not to support sharing. In this session, I'll show you how to easily build applications that use NSPersistentCloudKitContainer to share data with multiple iCloud users. The class contains all the necessary methods and properties you need to interact with Core Data. For iOS and macOS, Apple provides a robust toolkit, called CloudKit API, which allows developers targeting Apple platforms to solve this synchronization problem. catalogue of 50+ books and 4,000+ videos. Saving records is, perhaps, the most complicated operation. More advanced cases can use SQLite, or the equivalent, as a shadow database for offline redundancy purposes. based on the relationship they have to other objects. 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'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. we have built in to NSPersistentCloudKitContainer. It accepts the share and adds the necessary metadata into the sharedPersistentStore. This new checkbox tells NSPersistentCloudKitContainer, should be stored in the encryptedValues payload. First, update your container type to NSPersistentCloudKitContainer. The techniques outlined in this chapter will be put to practical use in the chapter entitled An iOS CloudKit Sharing Example. From here, tap the Share button in the top-right corner. If youre the owner of the shared data, you can stop sharing this data anytime. If theres no error, the title of the share is set. In fact, in a sense, youre recreating the convenience APIs. Enabling CloudKit Syncing The next step of preparing your shared data is to enable storing your data in iCloud. the main reason the SharingProvider exists: testing. This involves the creation of a CKFetchRecordsOperation object using the record ID contained within the CKShareMetadata object. Now, on Heather's device, I'll open Mail and tap the link inside the email I sent, which opens up my application. In this example, theres just the one record, but for future expandability, this is a great potential performance benefit. Launching the CI/CD and R Collectives and community editing features for How to share Core Data between multiple users? I've already saved Heather and Mary in my address book. The CKFetchRecordsOperation operates on one or more records at a time. 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.). The first step does a one-time setup in preparation for writing the record, and the second step passes the assembled record down to the singleton CloudKitNoteDatabase class. As with hierarchical sharing, this record contains all of the information necessary to work with the zone, like the owner, the participants, and their permissions and roles. 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 convenience API is much more accessible, while the operation approach can be a bit intimidating. Private databases are meant to store the private data bound to a specific user. Making statements based on opinion; back them up with references or personal experience. Now, encryption with CloudKit is an at-introduction time decision. Theres one minor bug with your app at the moment. In many cases, it can infer where records belong based on the relationship they have to other objects. to store objects in a specific shared zone. When a record is shared, a share link is sent to the recipient user in the form of a URL. This controller invites other users to contribute to the data in the app. where my friends and I can share our photos with each other.

What's the difference between a power rail and a signal line? Amazing! to store the objects an application creates. These values are stored in a new payload on CKRecord called encryptedValues, introduced in the "What's New in CloudKit" session. Connect and share knowledge within a single location that is structured and easy to search. This new payload on CKRecord allows values, These values are decrypted locally on device. Two separate iCloud accounts To initiate the sharing process. The same note fields for text and modified datetime can be stored locally in a file via NSKeyedArchiver or the like, and the UI can provide near full functionality based on this local copy. As you prepare to present your CloudSharingView, you need this property because the second parameter of CloudSharingView is a CKContainer. Every app automatically gets a default CKContainer, and a group of apps can share a custom CKContainer if permission settings allow. With the introduction of CloudKit sharing it is now possible for individual app users to share private database records with other users. That method works for documents saved to the current iCloud account. and how that affects the types of experiences you can build. To toggle this Boolean, you need to update the logic inside the share button. Now I'm going to add a new post, give it a title, and tap Done. Third, create an iCloud container that hosts your data in iCloud. This is new iOS 15 and allows NSPersistentCloudKitContainer to be configured to mirror persistent stores to the .shared CloudKit database. This is a thorny problem with many gotchas and pitfalls, but users expect the feature, and expect it to work well. 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. More importantly, you have a foundation for adding more advanced CloudKit functionality. Clash between mismath's \C and babel with russian. The end goal is not only to display shared entries but also to get information about the people participating in the share. From here, you store a reference to CKShare that returns from the share method. but the resulting confidence and reliability are well worth it. Once youve completed these steps, the data in your app then automagically sync with iCloud. See the solution below: [spoiler title=Solution 2] If it is shared, I may need to fetch the CKShare or the participants for that object to display more information in my user interface. 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. Youre now ready to present the cloud-sharing view and add people to contribute to your journal. to show that the post is part of a share. Next, open DestinationDetailView.swift. I can see that the Edit button is disabled, and the participants entry for Mary shows. For iOS and macOS, Apple provides a robust toolkit, called CloudKit API, which allows developers targeting Apple platforms to solve this synchronization problem. I can send it to my friends as an iMessage or email. For example, the zone that NSPersistentCloudKitContainer manages. How can I change a sentence based upon input to a command? We call them the owner and the participants. and the cells that correspond to unshared objects don't. NSPersistentCloudKitContainer shares objects. Once you accept the share on the second device, its now part of your shared zone in iCloud. Is something like this (or even better) available with the new CloudKit? A general guideline is to use com.company_name.bundle_identifier. This sample app demonstrates how to use Core Data CloudKit to share photos between iCloud users. The first step is to create a method that prepares your shared data. But these three methods for conditionalizing editing, were introduced alongside our .public database support, You can use these methods in your applications. So I'll tap Mail and then enter the information for my friends. Heather, Jermaine, Percy, and Mary are all test accounts. and some of the permissions on the shared album. Users may not be signed in, they may have disabled CloudKit for the app, they may be in airplane modethe list of exceptions goes on. uses Record Zone Sharing to share managed objects. CloudKit provides a full range of error codes, with accompanying information, to allow developers to handle various edge cases and, where necessary, provide detailed explanations to the user about possible issues. and modify records in these shared zones. The version held by the server at the time you submitted the request. If it is, then this object is already shared. I'll give it a simple title-- "Sharing demos are great"-- and tap Done. However, to allow other users to interact with this data, you need to update your NSPersistentCloudKitContainer. Amazing! We can see here that Jermaine is the owner. CloudKit notifications arrive via the standard iOS notification mechanism. Our users need all of that information so that they can make good decisions about the objects they choose to share. Hiring? It is also possible to serialize CKRecords directly to and from local storage. Instead of invoking methods on NSPersistentCloudKitContainer. 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. that controls who can access these zones that I own. Pauls been a developer for nearly three decades, working with many tech stacks but with a focus on Apple.

Below the Data section, click Records. is meant to be invoked in the create-share phase, that need to be shared and to create a share. we think of our objects in terms of NSManagedObject. Even in this humble sample application, I've had to make a number of changes to the user interface to present information about shared objects. Jordan's line about intimate parties in The Great Gatsby? After the share has been saved to the database, the cloud sharing controller needs to be notified that the share is ready to be sent. So that's how we use NSPersistentCloudKitContainer to combine the .private and .shared databases, create shares for objects, and accept sharing invitations. We've enabled adoption of encrypted values. Tapping that brings up the set of participants. all of the shared objects into the local store. [music]. Syncing a Core Data Store with the Cloud. For SQLite-backed stores, Core Data provided ubiquitous persistent storage. NSPersistentCloudKitContainer turns those managed objects. The SharingProvider has methods for binding. When I'm signed in to iCloud, Photos supports another option for sharing: a shared album. CloudKit provides you ready to use data sharing API that allows you to implement collaborative features of your app without much effort. To delete the destination, swipe left to reveal the delete button. An error occurred when submitting your query. and the participants entry for Jermaine shows. The way to enable these silent notifications is to set the shouldSendContentAvailable property on the CKNotificationInfo instance, while leaving all of the traditional notification settings (shouldBadge, soundName, and so on) unset. Thats it! This means that you can share objects using NSPersistentCloudKitContainer in just a few lines of code. [/spoiler]. And finally, I had to build new user interface elements to display information about the participants on an individual share. Last, if the current user of that share is the owner, returns. This is your Destination entity in Core Data. Enter a topic above and jump straight to the good stuff. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Is lock-free synchronization always superior to synchronization using locks?

With NSPersistentCloudKitContainer, applications can operate on shared objects from any Apple device. Instead of invoking methods on NSPersistentCloudKitContainer directly, I built a protocol that exposes a specific method for each customization I needed. that constrain how they can act on a particular set of objects. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. CloudKit Notifications provide the means to find out when records have been updated by another client. To learn more, see our tips on writing great answers. 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. Let's get started with sharing. All the user needs to do at this point is enter the contact details for the intended share recipient and send the message. This new checkbox tells NSPersistentCloudKitContainer that the value for this attribute should be stored in the encryptedValues payload of the resulting CKRecord. And finally, we'll briefly discuss how NSPersistentCloudKitContainer can help you enable some additional protection for sensitive data stored in iCloud. If I select the location attribute, I can see its configuration in the data model inspector on the right. 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). Also, to change the sharing permissions because it doesnt work properly on a simulator. And I'd like to show you one specific call site.
