iOS Simulator 17.4 "native crash" on Template Solution #15135

Closed dgor82 closed 2 months ago

dgor82 commented 6 months ago

Describe the bug

With a clean Avalonia Cross-Platform Template Solution, on macOS 14.4.1 (with Rider 2023.3.4) and Xcode 15.3, when running on iOS Simulator (17.4), it crashes with the following error output. On Android simulator AND on a physical iPhone connected to the mac via cable, there is no problem and the Hello World app launches as expected:

Feel free to reach out to me if you want a screen sharing session to help reproduce or check my environment.

maxkatz6 commented 6 months ago

Please check 11.1.0-beta1 version or latest nightly builds.

StefanKoell commented 5 months ago

I'm seeing the same issue with bate and latest nightly. For me I see the same crashes for 17.2 and 17.01 simulators. Creating a blank MAUI template works flawlessly, btw. Not sure if this helps to pinpoint the issue.

ztl8702 commented 5 months ago

I had a similar crash issue today (sometimes SIGABRT instead of SIGBUS), on an Avalonia-based application codebase.

I haven't built this particular codebase for iOS in a while. I was last able to run it on iOS about two months ago. Since then, multiple variables have changed: .NET SDK version, Avalonia version, XCode's iOS SDK and simulator versions. So I haven't figured out what is the root cause.

Here is one of the macOS crash reports when running on iOS simulator: https://gist.github.com/ztl8702/6b5da929be35b89f46dcdfbef3c73424#file-gistfile1-txt

My workaround is just to use a real iPhone for now.

Dynaruid commented 4 months ago

I've found a temporary workaround for the issue where the app crashes on startup when targeting the iOS simulator. Noting that the app can start on a real device but crashes in the simulator, I tried to build the app based on x64 architecture. Since the arm64 iOS simulator can also run x64 iOS apps, try this command line: dotnet build -t:Run -r iossimulator-x64 -p:_DeviceName=:v2:udid=SIMULATOR_ID.

Can somebody report this issue to https://github.com/xamarin/xamarin-macios ? Preferably with a minimal repro.

ztl8702 commented 4 months ago

@maxkatz6 I think this might be related to https://github.com/dotnet/runtime/issues/98941 or https://github.com/xamarin/xamarin-macios/issues/20257, apparently fixed in .NET 8.0.5 (I haven't tested personally). But anyway high chance that this is unrelated to Avalonia.

@maxkatz6 I've faced the same issue in iOS Simulator for both 17.4 and 17.5 versions, crashed on start up

maxkatz6 commented 2 months ago

@redradist

  1. Switch to iossimulator-x64, see https://github.com/AvaloniaUI/Avalonia/issues/14933#issuecomment-2179878357. Or pin to latest SDK 8.0.301.
  2. Optional, but likely is required, switch to Metal - https://github.com/xamarin/xamarin-macios/issues/20657#issuecomment-2143514751

Closing this issue, as this problem is tracked in https://github.com/AvaloniaUI/Avalonia/issues/14933

@redradist

1. Switch to iossimulator-x64, see [iOS crashes on iossimulator-arm64 with OpenGLES rendering #14933 (comment)](https://github.com/AvaloniaUI/Avalonia/issues/14933#issuecomment-2179878357). Or pin to latest SDK 8.0.301.

2. Optional, but likely is required, switch to Metal - [Simple net8.0-ios app - native crash at startup (Avalonia XPAT project) xamarin/xamarin-macios#20657 (comment)](https://github.com/xamarin/xamarin-macios/issues/20657#issuecomment-2143514751)

Closing this issue, as this problem is tracked in #14933

@maxkatz6 Why switch to iossimulator-x64 if I work on MacBook M1 Pro ?
