Hi, I'm from the App Center SDKs team. After updating Xcode from 12.4 to 12.5 our team faced build issues similar to this: Multiple commands produce '/Users/user/Library/Developer/Xcode/DerivedData/AppCenter/Build/Products/Debug-iphonesimulator/AppCenter.framework': 1) Command: ProcessXCFramework /Users/user/appcenter-sdk-apple/AppCenter-SDK-Apple/XCFramework/AppCenter.xcframework /Users/user/Library/Developer/Xcode/DerivedData/AppCenter/Build/Products/Debug-iphonesimulator/AppCenter.framework ios simulator 2) Target 'AppCenter iOS Framework' has create directory command with output '/Users/user/Library/Developer/Xcode/DerivedData/AppCenter/Build/Products/Debug-iphonesimulator/AppCenter.framework' Repro steps: Build AppCenter iOS Framework target. Build AppCenter target which creates an xcframework for iOS, macOS, and tvOS platforms. Build AppCenter iOS Framework and/or AppCenter Analytics iOS Framework target. Build SasquatchPuppet target (it uses AppCenter iOS Framework and AppCenter Analytics Framework targets). After the issue happened only Product > Clean build folder can help. We've tried to automate cleaning the build artifacts (BUILD_DIR) etc, but it doesn't help. Also, we've tried to use separate Product Names for XCFramework and mere Frameworks, but it was not possible for us in the end because of the xcconfig variables visibility.
