This is also the case for macOS architectures as well. Both macos-x86_64 and macos-arm64 represent two equivalent library definitions. It seems like using lipo for these combinations might be necessary: ios-arm64-simulator and ios-x86_64-simulator ios-arm64-maccatalyst and ios-x86_64-maccatalyst macos-x86_64 and macos-arm64 What I'm not sure about is how these will end up in the xcframework subfolders. edit: using lipo is necessary, and is the accepted solution for this.
