It's good to post screenshot but you should also post as code text, that's easier to handle.

  • where does it crash exactly: on targets definition ? on traces definition ?
  • which Xcode version (should test with 13.2..1)
  • How is queue defined ?

Note: you could rewrite the test as

            let newTrace = (trace != nil && !trace!.isEmpty) ? trace! : "0"

setValue(forKey:) is a key-value coding (KVC) method. You should be using the UserDefaults specific method, namely set(forKey:). I don’t think that’ll fix this problem, but it’s the right thing to do regardless.

Also, the screen shot you posted doesn’t align with the crash report. The former indicates a force unwrap issue whereas the latter shows a crash deep within UserDefaults. Are you chasing two issues? If not, why this disparity?

Share and Enjoy

Does anyone find the wayout? I got same question when invoke [[NSUserDefaults standardUserDefaults] setObject:value forKey:key] in sub thread.

That crash report suggests that you’re crashing here. This is deep within the Objective-C runtime, where it’s doing a pointer authentication on a class pointer. This is usually due to some sort of memory management bug, but as to whether that’s your bug or a bug in the system it’s hard to say. We’re deep in KVO here, and KVO has known race conditions that could cause a crash like this.

To start, I recommend that you test your app thoroughly with the standard memory debugging tools. The goal here is that, if there is a memory mangement bug on your side, this will help flush it you so that you can fix it.

I've noticed that AppStorage uses KVO to observe NSUserDefaults. Is it possible that using AppStorage causes writing to NSUserDefaults to no longer be thread-safe, since SwiftUI will get notified on the wrong thread?

After further investigation, I have confirmed the following (submitted as FB12348064):

The AppStorage property wrapper uses KVO to observe UserDefaults. This makes writing to UserDefaults unsafe on non-main threads, even if the AppStorage is not using the same key as is being written. Any write to UserDefaults causes a lookup of all observers. If the AppStorage is deallocated during that lookup, there will be a crash.

The following reliably crashes for me within a few hundred iterations, tested with both Xcode 14.3.1 and 15b1:

import SwiftUI

struct ContentView: View {
    @State var n: Int = 0

    // This song-and-dance is to make sure that AppStorageView is destroyed and recreated.
    // The two views are visually identical to make the output easier to read. One has @AppStorage,
    // the other does not. This causes very fast registering/deregistering from UserDefaults KVO.
    func bodyView() -> AnyView {
        if n % 2 == 0 {
            return AnyView(
                ForEach(0..<10) { _ in
                    AppStorageView(n: n)
                })
        } else {
            return AnyView(
                ForEach(0..<10) { _ in
                    NoAppStorageView(n: n)
                })
        }
    }

    var body: some View {
        bodyView()
            .task {
                // Churn UserDefaults on a background thread.
                Task.detached {
                    while true {
                        UserDefaults.standard.set(Date(), forKey: "randomOtherUserDefaultsKey")
                        await Task.yield()
                    }
                }

                // At the same time, churn the Views to create and destroy AppStorage observations.
                while true {
                    n += 1
                    await Task.yield()
                }
            }
    }
}

// View with @AppStorage observation
struct AppStorageView: View {
    var n: Int

    @AppStorage("appStorageValue") var appStorageValue = false

    var body: some View { LogView(n: n) }
}

// View without @AppStorage observation
struct NoAppStorageView: View {
    var n: Int

    var body: some View { LogView(n: n) }
}

struct LogView: View {
    var n: Int
    var body: some View {
        HStack {
            Text("App Storage Test: \(n)")
            Spacer()
        }
    }
}
