Any suggestions for what to try to get around this error? Thank you!

Which OS version you are on? And which Xcode? Seems like a mismatch of compiler / macOS.

[alanf]

OS: Monterey 12.6.1 (21G217)
Xcode: 14.1 but I also have 13.3.1 installed

[liuliu]

And xcode-select -p is showing the Xcode 14.1 path?

[alanf]

It is:
/Applications/Xcode.app/Contents/Developer
(the other Xcode is named Xcode-13.3.1)

[liuliu]

Thanks. This error feels like the one I encountered sometime ago for another project, when there is a mismatch in declared macOS compatibility with the available SDK. Need to dig into it to find what's the fix last time. Won't have time until Friday.

[alanf]

Thanks for looking!

[liuliu]

Thanks. I now think this is related to Xcode 14.1, and basically the binaries built with Bazel rules_swift needs to specify its minimal supported macOS version otherwise Xcode 14.1 is going to build with macOS 13's toolchain. Easy solution is to upgrade to macOS 13.0.

[jiangdi0924]

@liuliu after upgrade macOS version it worked well, Much appreciated ！！！
Now I have another question，I have no experience with bazel, how should I use the packages generated by bazel integration my macOS or iOS project?
😊Many thanks～～～

[liuliu]

Thanks! Yeah, Bazel is not the easiest to use, to integrate with Xcode project, I recommend to try https://github.com/buildbuddy-io/rules_xcodeproj

I do plan to package this for SPM, but won't get much time until December (need to add new samplers, CLI etc to this repo from draw-things repo). Constantly get distracted because newer models etc etc.
