Hmm, since updating to #dotnet 7, my #maui app in iOS is failing with clang exit code 1.

No code has changed, all workloads at up to date and all NuGet packages are at their latest version.

Any pointers?

Android is building and deploying fine.

@JayHayman taking a look at a binlog will certainly give more information. https://msbuildlog.com/

@JayHayman Update Xcode (use the amazing Xcodes.app to speed up the upgrade) and - most importantly - run the Xcode at least once to enable the correct SDKs.

@filipnavara Ah, Xcodes is nice, using that from now on.

Xcode is up to date with 14.1, can build and deploy to the iOS simulator from Xcode, and same from a VS Mac with a MAUI app, just seems to be from VS Windows side I'm having the problem.

@JayHayman Normally I'd follow @jlaban's recommendation to use binlog and msbuildlog.com analyzer. The `-framework System` part of the error message clearly points to some problem with the SDK installation.
