I'm trying to build and run my app from Xcode 12 but the ProcessXCFramework step fails telling me that it could'n't copy the headers from my xcframework files : ProcessXCFramework /Users/username/xyz_no_spaces/libgpg-error.xcframework (in target 'MyApp' from project 'MyApp') 		cd /Users/username/xyz_no_spaces/MyApp 		builtin-process-xcframework --xcframework /Users/username/xyz_no_spaces/libgpg-error.xcframework --platform ios --target-path /Users/username/Library/Developer/Xcode/DerivedData/MyApp-gyqvfqslpvdvpubdhccubciywesh/Build/Products/Debug-iphoneos error: “gpg-error.h” couldn’t be copied to “Debug-iphoneos” because an item with the same name already exists. (in target 'MyApp' from project 'MyApp') Note: the file does not already exist at the target path (or maybe it's just deleted after it fails, I don't know..) I get this message for all 6 of my xcframeworks which are all set to 'Do not embed'. Works fine on Xcode 11. So I guess it's either an Xcode 12 bug or I need to check a box somewhere when moving to 12. I've tried removing the frameworks completely and re-adding them. Nuking the DerivedData folder and recompiling from scratch. No love. :( Has anyone found a workaround for this? In case my frameworks are somehow malformed (I did merge ios-x86_64-maccatalyst dylibs into them back in the day, but removing them makes no difference) maybe someone can spot what's wrong with this example file structure: libgpg-error.xcframework Info.plist ios-armv7_armv7s_arm64 Headers gpg-error.h libgpg-error.a ios-i386_x86_64-simulator Headers gpg-error.h libgpg-error.a ios-x86_64-maccatalyst Headers gpg-error.h libgpg-error.a Lipo -info on all of the dylibs match the architectures in the folder names. (And has worked fine for the last year using Xcode 11.)
