Microsoft.AppCenter.Crashes clang++ exited with code 1 when compiling for ios-simulator on pair arm64 mac in VS for Windows

Description

If you try to use the Microsoft.AppCenter.Crashes in a .net maui app in Visual Studio for Windows paired with an arm64 Mac, deploying to the ios simulator, then you get an error:

Repro Steps

1. Create new maui app in VS for Windows
2. Pair to Mac (arm64 - eg. m1 or m2)
3. Build and deploy to ios simulator

Details

1. What is your app platform (Xamarin.Android or Xamarin.iOS or UWP)?
   • e.g. MAUI on all 3 platforms (Android, iOS and UWP).
2. If using Xamarin.Forms or if using portable/shared code to call our SDK APIs, are you using shared project, PCL code or .NET standard code for the application? Which .NET standard version or which PCL profile?
   • e.g. Multitargeting
3. Which SDK version are you using?
   • e.g. 5.0.2
4. Which OS version did you experience the issue on?
   • e.g. iOS 16.4 Simulator
5. What device version did you see this error on? Were you using an emulator or a physical device?
   • e.g. iPhone 14 Simulator running iOS 16.4
6. What third party libraries are you using?
   • Just yours
7. Please enable verbose logging for your app using AppCenter.LogLevel = LogLevel.Verbose before your call to AppCenter.Start(...) and include the logs here:

I have the same error for MAUI app with the iOS simulator on Mac since I upgraded to .net 8

[FM1973]

I got the same problem.
I my case I´ve installed .net RC1 as well. But I got the problem when using AppCenter in .net 7 with MAUI 7.0.59.

[rogerbriggen-securiton]

Same here. After installing dotnet 8 RC1 on the mac I have the same problem when compiling for dotnet 8.
Note: I am building on the mac from the console so it is not about windows and pair but it is just the compilation on the mac.

Hope this will be fixed soon. Very easy to reproduce

Same issue when upgrading MAUI workloads from 7.0.86 to 7.0.92 as well as from .NET SDK 7.0.302 to 7.0.401, on both Windows and paired Mac. Pretty sure my Xcode on the ARM64 Mac was already on 14.3 and this was working just fine before the .NET upgrades. I also updated the AppCenter nuget from 5.0.2 to 5.0.3, but same results.

Ultimately the suggestion by the MAUI team on another thread allowed me to build and deploy to an iOS simulator, but not sure if there are any side-effects yet. Have not yet tried on a physical device, or release deployment for that matter.

Quick fix:

<PropertyGroup Condition="'$(Configuration)|$(TargetFramework)|$(Platform)'=='Debug|net7.0-ios|AnyCPU'">
    <ForceSimulatorX64ArchitectureInIDE>true</ForceSimulatorX64ArchitectureInIDE>
</PropertyGroup>

For the MS-AppCenter team, the MAUI team suggested the following for the reason for the issue:

Rolf Bjarne Kvinge (@rolfbjarne): Looks like AppCenter doesn't ship support for the iossimulator-arm64 architecture, so this is an AppCenter issue.

Experiencing the same issue.

Hope this will be fixed soon. Very easy to reproduce

dotnet new ios
dotnet add package Microsoft.AppCenter.Analytics
dotnet build

The build succeeded for me using your steps. Are you building it on intel or m1/m2 mac?

[tipa]

I am building on a M1 Mac. Make sure it creates and builds the project with .NET 8 - it builds as expected with .NET 7. I just tested again with .NET 8 RC 2 and the error still shows

Build FAILED.

[DmitriyKirakosyan]

That's intriguing. For Mac users, the issue appears only on .NET 8. However, when building from Windows in conjunction with Mac, it's reproducible on .NET 7.

If the problem stemmed from a missing architecture in the AppCenter SDK binary, it would be present across all versions of .NET. I suspect this might be a .NET-related issue. Let's keep this open and gather additional details about this problem.

If anyone has a solution or suggestion, contributions are always appreciated!

If the problem stemmed from a missing architecture in the AppCenter SDK binary, it would be present across all versions of .NET. I suspect this might be a .NET-related issue. Let's keep this open and gather additional details about this problem.

It's an AppCenter SDK issue, the problem is that the AppCenter SDK doesn't support arm64 in the simulator.

The difference is that in later versions .NET/IDE we've changed the default architecture (RuntimeIdentifier) we build for the simulator when building on an arm64 mac: in initial .NET 6 + .NET 7 releases the default was iossimulator-x64, now (in .NET 8 + some versions of .NET 7 depending on the VS version) it's iossimulator-arm64 when building on an arm64 mac.

That's why the workaround works in the IDE:

<PropertyGroup Condition="'$(Configuration)|$(TargetFramework)|$(Platform)'=='Debug|net7.0-ios|AnyCPU'">
    <ForceSimulatorX64ArchitectureInIDE>true</ForceSimulatorX64ArchitectureInIDE>
</PropertyGroup>

It forces using iossimulator-x64 when building from the IDE.

Note that device builds are not affected in any way.

This has been biting us for a while too as we much prefer to develop using the ARM64 Simulator on our Apple Silicon Macs, but it's currently not possible for dotnet projects - we are either forced to use the x64 sim via Rosetta (using Rolf Bjarne Kvinge (@rolfbjarne)'s suggested workaround above), or remove references to the AppCenter packages.

I suspect a lot of folks don't realise that ARM64 simulator and ARM64 device binaries are two different, non-compatible things & support for both requires bundling XCFrameworks inside the nupkg payloads, containing both the ios-arm64 and ios-arm64-simulator (or ios-arm64_x86_64-simulator) sub-frameworks.

See here for more information (including lots of good stuff from Rolf Bjarne Kvinge (@rolfbjarne))

[Hooterr]

It's not a deal breaker, but it'd certainly be nice to be able to run arm64 simulator. When run in x64 mode, the simulator is (imo) a bit slower, and there's a scrolling bug. You can't fling a scrollview or collection (it's an iOS bug but MAUI, same happens in Swift app).

Out of all the packages we have only appcenter is not compatible with arm64. What we have is a build profile that removes dependency on AppCenter and in code we check for that build profile so that we don't call any AppCenter APIs.

[sledderGIT]

Experiencing the same issue. Have to exclude Appcenter from my Solution.

I tried this doesn't work, but I'm using .NET8 I did this:

	<ForceSimulatorX64ArchitectureInIDE>true</ForceSimulatorX64ArchitectureInIDE>
