So after some investigation. I found having the async setup() function caused this behaviour to prevent retries. When moving to the synchronous setup function I no longer get issue. The problem being I need to do async code in my setup... If I move my code to the following, test repetitions now work and I see no such errors override func setUp() { super.setUp() continueAfterFailure = false // setup async seems to prevent test repetitions from working let exp = expectation(description: "setup") Task { try await setupWebApp(router: router) exp.fulfill() } wait(for: [exp], timeout: 10) }

I’m seeing the same behaviour and it’s causing my test repetition mode to not fire and thus it doesn’t re-run tests

Many thanks Eskimo I will have a dig into this further. This is part of a popular UI library called Texture so I don't imagine I'm the only one facing issues with the framework initialiser and the workaround resides in a third party library.

I have a spindump of the running simulator after the tests timeout if it'll help Eskimo Without a good understanding on how to analyse spin dumps. I see this at the bottom of the main apps running. It looks like two threads are waiting on each other and causing the deadlock (blocked by turnstile waiting for AppName [66373] [unique pid 463253] thread 0x8ffc2e) 1-204 drive.google.com/file/d/1KhdlKf5v77cVuiOQ-T1ZUGSKrVLobCzs/view?usp=sharing

I think it's a bit tricker than that unforunately. I can get you a spindump file of our project deadlocking during testing if that will help. I think it's also happening during normal function of the app too, users are reporting being stuck on a screen before the splash and the UIApplicationDelegate callbacks didFinishLaunchingWithOptions are never called. Looks like a UIKit bug causing a deadlock. I'm using Texture as a pod and I believe the deadlock is happening during some initialisation code where UIKit is called to create a layer. Looks like the deadlock is happening inside UIKit https://github.com/TextureGroup/Texture/issues/2029

No luck so far, I get a spindump which is a bit tricky to read after it fails. Not sure if Eskimo is about to help answer this? When I run against a iOS 14 simulator or less it works fine

I am seeing the same behaviour. Strangley UITest run fine with a couple of minor differences from XCode 12. But Unit tests compile and just block the simulator and won't run eventually timing out. XCode 13 RC, on Big Sur 11.6
