SubscribeCheck out our SwiftData Quick Start GuideIf your system attempts to access a SwiftData object after it has been deleted, the app will crash and the stack trace will point to the parameter that you are trying to access in the SwiftData model.
For example, the code below will cause a crash when an app tries to access the id parameter of an object that has been deleted.
if let object = self.object, let id = object.id {}To solve this crash, use the isDeleted parameter, as shown below.
if let object = self.object, !object.isDeleted, let id = object.id {}Looking to learn more about things you can do with SwiftData, Swift or XCode ?
