How to delete an object from SwiftData in Swift

The following tutorial has been made available, along with a simple app for demonstrating SwiftData, through the tutorial/swift-data-basics branch on our Open Source Swift Starter Project.

Follow the tutorials linked below to add SwiftData to your project, along with the ability to search for all objects, a specific object as well as if an object exists.

Add functionality similar that below to the project to check if an object exists within your SwiftData persistent storage container.

We recommend adding this to a file called DataCoordinator+SwiftData.swift, where DataCoordinator is the name of the MainActor singleton that manages the SwiftData.

Please note that the code snippet found above uses a custom error that we created to track SwiftData errors. To learn how to create custom errors, consult the tutorial below.

Add functionality to delete SwiftData objects by calling the function created in Step Two.

Then, run the app and test that it works.

Consult our quick start guide or search our blog to find educational content on learning how to use SwiftData, Swift or XCode.
