Describe the bug We're experiencing somewhat regular main thread hangs that appear to be related to lock usage in the SDK. Attaching images below.

  1. Environment
    1. Platform: iOS
    2. SDK version: 5.2.2
    3. StoreKit version:
      • [x] StoreKit 1
      • [ ] StoreKit 2 (enabled with usesStoreKit2IfAvailable(true))
    4. OS version: 17.5

      • [x] Simulator
    7. Environment:
      • [x] Sandbox
      • [ ] TestFlight
      • [ ] Production
    8. How widespread is the issue. Percentage of devices affected. ~20% of app runs.
  2. Debug logs that reproduce the issue. Complete logs with Purchases.logLevel = .verbose will help us debug this issue.

  1. Steps to reproduce, with a description of expected vs. actual behavior Swift UI project targeting iOS 16+. The SDK is configured within the scope of the App's init:

    @main
struct App {
init() {
    self._viewModel = StateObject(wrappedValue: AppViewModel(appRouter: router))
}
}

    The SDK is initialised in a Task of the ViewModel's initialiser. The init is executed on the MainActor as it's called from the App, so the SDK call to Purchases.configure(withAPIKey: apiKey, appUserID: nil) will be using that parent scope.

  2. Other information (e.g. stacktraces, related issues, suggestions how to fix, links for us to have context, eg. stackoverflow, etc.) There's what could be related PR open although the console says "Purchases is configured with StoreKit version 2" Threads-1 Threads-2

  3. Additional context Add any other context about the problem here.

@tristan-warner-smith thanks for reporting! It does feel related to the bug that @joshdholtz's PR fixes, despite the console output, since we get the storefront through SK1 even if SK2 is enabled

@aboedo I've tried out @joshdholtz's PR and it did make a difference but unfortunately didn't go far enough. Here's where it's locking subsequently: Screenshot 2024-07-31 at 13 52 59

And here's a crash log we got with it: crashlog.txt
