Like https://forums.developer.apple.com/message/389765#389765, I am trying to create an xcframework file for a few third party libraries I'm using. Following the instructions from https://appspector.com/blog/xcframeworks, I1. Create platform-specific framework files:# Archive for device xcodebuild archive -scheme TestFramework -destination="iOS" -archivePath /tmp/xcf/ios.xcarchive -derivedDataPath /tmp/iphoneos -sdk iphoneos SKIP_INSTALL=NO BUILD_LIBRARIES_FOR_DISTRIBUTION=YES # Archive for simulator xcodebuild archive -scheme TestFramework -destination="iOS Simulator" -archivePath /tmp/xcf/iossimulator.xcarchive -derivedDataPath /tmp/iphoneos -sdk iphonesimulator SKIP_INSTALL=NO BUILD_LIBRARIES_FOR_DISTRIBUTION=YESAt this point, I've gotten two frameworks with swiftmodule files; everything looks good. The frameworks do *not* come with swiftinterfacefiles, but I think that is alright as these are objc projects. Then, I2. Combine the individual frameworks to form a single xcframework file:# Build xcframework with two archives xcodebuild -create-xcframework -framework /tmp/xcf/ios.xcarchive/Products/Library/Frameworks/TestFramework.framework -framework /tmp/xcf/iossimulator.xcarchive/Products/Library/Frameworks/TestFramework.framework -output /tmp/xcf/TestFramework.xcframeworkHere, xcodebuild doesn't fail, but it emits a curious error:No 'swiftinterface' files found within '/Users/user/git/ReactiveObjC/output/xcf/ios.xcarchive/Products/Products/Library/TestFramework.framework/Modules/TestFramework.swiftmodule'.Crucially, the xcframework package does not contain the individual frameworks or folders specified in the Info.plist file. Obviously, when I try to link to the xcframework in this state, I get a bunch of "missing symbols" linker errors.Why is this? What must I do to get xcodebuild to create the xcframework completely?NB: Manually creating the folders seems to work for now, but this feels wrong and is brittle – Apple can change the way xcodebuild works anytime.
