This looks promising! Does task executor preference address some of the issues raised in this thread? > [@Reliably testing code that adopts Swift Concurrency?](https://forums.swift.org/t/reliably-testing-code-that-adopts-swift-concurrency/57304): > > I’m having a hard time figuring out how to test application code as it adopts async-await and begins to be scheduled concurrently. I’ll try to show a simple example. Here’s a basic SwiftUI application that tracks how many times a user has taken a screen shot. It has a view model with an endpoint that spins off some async work, and then the view calls this endpoint when it first appears: class ViewModel: ObservableObject { @Published var count = 0 @MainActor func task() async { let … More specifically, do these tools provide a more structured way of testing async code in a serialized way without having to resort to overriding the `swift_task_enqueueGlobal_hook`? --- _[View the full topic](https://forums.swift.org/t/pitch-task-executor-preference/68191)._
