Hi, having the concurrency checks (-Xfrontend -warn-concurrency -Xfrontend -enable-actor-data-race-checks-Xfrontend -warn-concurrency -Xfrontend -enable-actor-data-race-checks) enabled I always get this warning, when trying to access/use an actor in a SwiftUI .task: "Cannot use parameter 'self' with a non-sendable type 'ContentView' from concurrently-executed code". What would be a correct implementation? Here's a minimal code-sample which produces this warning: import SwiftUI struct ContentView: View { @State var someVar = 5 var a1 = A1() var body: some View { Text("Hello, world!") .padding() .task { await a1.doSomething() } } } public actor A1 { func doSomething() { print("Hello") } }

Hi, I am using a child NSManagedContext trying to isolate changes to a NSManagedObject from changes done to the same object in the parent NSManagedObjectContext. This works fine for normal properties, but any changes to relationships performed on the object in the parent context will show up immediately in the child object as well. Is this the intended behavior? If yes is there a way to create an "isolated" version of an NSManagedObject? Thanks in advance for any hints! Cheers, Michael
