xcframework-maker

macOS utility for converting fat-frameworks to SPM-compatible XCFramework with arm64-simulator support.

📝 Description

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.

The 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.

🛠 Build

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:

.build/release/make-xcframework

▶️ Usage

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:
- IMA SDK for iOS
- IMA SDK for tvOS
Unzip downloaded files.

Run make-xcframework:

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:
```
output/path/GoogleInteractiveMediaAds.xcframework
```
