Issues in running the MAUI app in Macbook

Question

We created a MAUI app using version .Net8.0. We are trying to debug/run the app by connecting Visual Studio to Mac, but we are encountering issues debugging the app. The pipeline is functioning as expected. Specifically, we're facing an issue with clang++ exiting with code 1, preventing deployment on the simulator.

Debug Configuration

<PropertyGroup Condition="'$(Configuration)|$(TargetFramework)|$(Platform)'=='Debug|net8.0-ios|iPhoneSimulator'"> <DebugType>full</DebugType> <Optimize>false</Optimize> <ErrorReport>prompt</ErrorReport> <RuntimeIdentifier>iossimulator-x64</RuntimeIdentifier> <WarningLevel>4</WarningLevel>     <CodesignEntitlements>Platforms\iOS\Entitlements.plist</CodesignEntitlements> <ForceSimulatorX64ArchitectureInIDE>true</ForceSimulatorX64ArchitectureInIDE> <PlatformTarget>arm64</PlatformTarget> <CodesignKey>iPhone Distribution</CodesignKey> <IPhoneResourcePrefix>Platforms/iOS/Resources</IPhoneResourcePrefix>

</PropertyGroup>

Hello,

This error is thrown by AppCenterCrashes SDK, and you are trying to debug your app on a simulator, however this SDK won't forward any crash log if you're attached to the debugger. See App Center Crashes for iOS - Visual Studio App Center | Microsoft Learn

In addition, AppCenter doesn't ship support for the iossimulator-arm64 architecture, and there is no plan to support the simulator, please do not set the configuration for simulators and run the app on your physical device.

For more details, please refer to

Microsoft.AppCenter.Crashes clang++ exited with code 1 when compiling for ios-simulator on pair arm64 mac in VS for Windows · Issue #1755 · microsoft/appcenter-sdk-dotnet (github.com)
