I have the same issue when building for visionOS. iOS and macOS succeeds. This fails both locally and on Xcode Cloud. Did you figure out how to fix it? C99 was enabled in PCH file but is currently disabled module file [some-directory]/Xcode/DerivedData/ModuleCache.noindex/SwiftShims-1VIPCI9266QTFHCU040GOH2D7.pcm cannot be loaded due to a configuration mismatch with the current compilation missing required module 'SwiftShims'

Same issue here

Wow thank you so much for the detailed response! I'll follow your suggestion to test it in sandbox first, if it doesn't work at all then I may just have to distribute outside of MAS. Since have you here, I have one more question. One of the conditions which I'd like to use for changing the Network Location is based on the name of the Wifi network that the user connects to. Is CoreWLAN what I should be using to detect Wifi changes?

Thank you for this. I also thought that my reply would show up to the user without line breaks. This helps a lot! Definitely a weird UI bug... and crazy that it's still present in 2025, 6 years after your comment. Who knows how long this has been an issue.

Your .onAppear example worked for me! Thanks!

Thank you!
