Thanks for the report. Can you share your version of Xcode and how you're configuring the build please?

What version of the library are you building? You can use git describe if building from a git tree.

Did you manually create the Xcode projects or use cmake to generate them? If you used cmake could you include the command or give some instruction in how the project was configured?

I don't see any warnings with cmake -G Xcode -DCMAKE_OSX_ARCHITECTURES=arm64 or x86_64 using Xcode 14.0.1 (14A400), but I may be missing something related to the configuration.

Any update on this one? I don't see any warnings with v1.2.4-130-g1d58575b targeting iOS or arm64 macOS.
