![]() XCSourceEditorCommandName - a command name as it will be displayed in the second level of Xcode Editor menu.Make sure you set it to something unique within your extension. XCSourceEditorCommandIdentifier - a command invocation identifier.Xcode has already created a command class with exact same name once you created the source editor target. XCSourceEditorCommandClassName - a name of the command class.Lets unfold it and inspect inner properties. Tap Activate when it prompts you Activate “SourceEditorExtension” scheme.Īt this point the targets must look like this:Īll editor extension targets contain an extra entry in their ist files named NSExtension. Now add Xcode Source Editor Extension Target to your newly created project. Xcode editor extensions cannot exist on their own and must be wired up to a macOS application.įirst off, we create a macOS project in Xcode named LinesSorter. By the end of this article, your command will look something like this: XCSourceTextBuffer - a buffer used to manipulate the text contents and selections in a source editor.Įxtension’s commands are accessible from Xcode Editor dropdown menu.As already noted, multiple invocations can be handled by a single XCSourceEditorCommand. XCSourceEditorCommandInvocation - an instance of the command sent to your extension.You must implement at least one of these in your extension. You can think of it as a sink where one or more command invocations are handled. XCSourceEditorCommand - the protocol that stands for the source editor command handler.You can think of it as an AppDelegate from your iOS and macOS apps. XCSourceEditorExtension - the protocol that every Xcode Source Editor Extension must implement.They can read and modify the contents of current source file, select and deselect text within that file. Extensions have quite limited functionality. You create extensions to the source editor by means of XcodeKit framework. Explaining Xcode Source Editor Extensions In this article you will learn how to create Xcode Source Editor Extension that adds some extra functionality to Xcode. Although it is well-integrated with the most development workflows, from time to time you might feel like missing some basic features. ![]() / Returns a URL for the given app group and database pointing to the sqlite database.Xcode is the core tool for Apple development. PersistentContainer.persistentStoreDescriptions = įor this, we’re making use of a handy URL extension to get the path to the shared container using the security application group identifier. Let storeDescription = NSPersistentStoreDescription(url: storeURL) ![]() Let storeURL = URL.storeURL(for: "", databaseName: "Coyote") Let persistentContainer = NSPersistentContainer(name: "Collect") You basically save your database into the shared App Container. You can do this by logging into your account at :Īdding the App Group to your App IdentifierĪfter that, you can update your persistent store description. Note that the App Group is turned into red when you didn’t add it to your App Identifier yet. This will eventually result in the following overview of app groups for your project:Īn overview of the app groups for your project We can do this by adding an app group capability within your projects “Signing & Capabilities” section:Īdding an app group to your project for Core Data sharing To share data we need to create a shared container between the main app and its extensions.

The app extension and containing app have no direct access to each other’s container, even though an app extension bundle is nested within its containing app’s bundle. Within the Collect App, we have a Share extension and an Action extension that both require the use of the same underlying persistent container. Sharing your Core Data database with your Today extension, Action extension or Share extension is something quite common if you’re using Core Data as your database solution. You can read more about it in my blog post Persistent History Tracking in Core Data. ![]() Starting from iOS 13 I recommend Persistent History Tracking as a solution to sharing a single database.
