Failed to build "xcrun exited with code 69" and "Class AppleTypeCRetimerRestoreInfoHelper is implemented in both"

Description

I created a MAUI project on Windows machine. Now I’ve installed Visual Studio for Mac on a Macbook Pro M1 with all options enabled to install. After the installer was done it told me to install Xcode which I did. Then I tried to simple run my project it said:

please run:

dotnet workload install mac-ios
dotnet workload install mac-android
dotnet workload install mac-catalyst

Which is very weird because I installed all of them through the official VS 2022 Preview for Mac installer. There were NO .NET sdks installed on this machine before, its brand new. Anyway after I ran the three commands the issues were gone but when I tried to do a simple debug rebuild and it fails with:

xcrun exited with code 69 and Class AppleTypeCRetimerRestoreInfoHelper is implemented in both /usr/lib/libauthinstall.dylib and /Library/Apple/System/Library/PrivateFrameworks/Versions/A/MobileDevice. One of the two will be used. Which one is undefined.

Like I said this is/was a brand new machine so its frustrating that running the official installer and debugging a simple project is impossible, like this has not been tested by someone. Any help is appreciated because all I want is to debug/build the iOS version on MacOS. For the rest I can fallback to a Windows machine.

//edit: I’ve now tried Visual studio Code instead of VS 2022 but this gives me the same error message when I run dotnet build -t:Run -f net6.0-ios

After watching plenty of youtube tutorials and reading guides on how to set it up I’ve figured out:

1. Despise I’m using an ARM64 Mac, installing the ARM64 .NET SDK was a problem. I also had to install the x64 SDK
2. Installing Xcode is not enough, it also needs to get started once and I needed to agree to the EULA

These two points are missing in the MAUI documentation and should definitely get added. After that these non-helpful error messages finally disappeared. Unfortunately now I’m stuck that as soon as I debug my app, it opens the iOS Simulator but VS 2022 says it cannot connect and the app in the iOS simulator crashes to home screen. If I open it in the iOS Simulator again it shows the splashscreen of the app but then all I got is a blank white screen on the simulated iphone. I don’t know why and I cannot debug either, on Android no problems. Remote debugging from Window to Mac doesn’t work either, I get a VS error giving me a link to a VS support ticket saying that the remote iOS Simulator is broken without ETA for a fix.

For a beginner with MAUI like me this is just a complex and frustrating experience. There isn’t much info about MAUI in the internet, mostly Xamarin (they all mention settings that do not exist in MAUI). But most guides or docs expect you to be either a mac expert or a xamarin expert because they are missing many steps in both directions. Please put more work into getting started with MAUI documentation and consider not everyone is coming from Xamarin or has developed on a Mac before.

Anyway this issue can possibly get closed.

In my case, I just needed to open XCode and accept the terms and conditions on my MAC. I have recently upgraded my MAC OS And this issue disappeared on next build. May be, it could be helpful for someone. thanks
