macOS utility for converting fat-frameworks to SPM-compatible XCFramework with arm64-simulator support.
make-xcframework is a simple command-line utility written in Swift that creates XCFramework file from fat framework files. The resulting XCFramework file can be added as a dependency to your Swift Package, using
.binaryTarget (read more in official documentation).
Optionally, arm64-simulator support can be included in the resulting XCFramework to allow development on a computer with Apple Silicon (M1) processor without a need to run Xcode through Rosetta.
xcframework-maker Swift Package contains
make-xcframework that can be used from the command line and
XCFrameworkMaker library that you can integrate with your Swift Package and use programmatically.
Note: arm64-to-sim is used to “hack” the native (device) arm64 architecture slice so it can be used in a simulator running on Apple Silicon. This is an experimental feature, and it can fail for many reasons. It was tested and proved to be working with the
GoogleInteractiveMediaAds dynamic fat framework, but your experience may vary.
Use Swift 5.4 for building the utility on macOS:
swift build -c release
You can copy the executable or run it directly from the build directory:
OVERVIEW: Utility for creating XCFramework from legacy fat-framework files. Use this tool to create XCFramework from legacy fat-framework files. Resulting XCFramework can be added as a dependency to your Swift Package. Optionally arm64-simulator support can be included in the resulting XCFramework, so it can be used on M1 Mac without the need to run Xcode through Rosetta. USAGE: make-xcframework [-ios <path>] [-tvos <path>] [-arm64sim] -output <path> [-verbose] OPTIONS: -ios <path> iOS input framework path. Provide a path to the iOS fat framework that should be included in the resulting XCFramework. Eg "path/to/iOS/Framework.framework" -tvos <path> tvOS input framework path. Provide a path to the tvOS fat framework that should be included in the resulting XCFramework. Eg "path/to/tvOS/Framework.framework" -arm64sim Add support for arm64 simulator. Use device-arm64 architecture slice as a simulator-arm64 architecture slice and include it the resulting XCFramework. This makes development possible on M1 Mac without using Rosetta. -output <path> Output directory path. Provide a path to a directory where the resulting XCFramework should be created. Eg "path/to/output/directory" -verbose Log detailed info to standard output. When this flag is provided, detailed information about each performed action is logged to standard output. -help, -h Show help information.
Example – GoogleInteractiveMediaAds
Download GoogleInteractiveMediaAds fat-frameworks from Google website:
Unzip downloaded files.
make-xcframework \ -ios path/to/ios/GoogleInteractiveMediaAds.framework \ -tvos path/to/tvos/GoogleInteractiveMediaAds.framework \ -arm64sim \ -output output/path
Resulting XCFramework will be created in the provided output directory:
