compile matrix-sdk-ffi libraries for iOS, the iOS simulator, MacOS, and Mac Catalyst under /target. Some targets are not part of the standard library and they will be built using the nightly toolchain.

lipo together the libraries for the same platform under /generated
run uniffi and generate the C header, module map and swift files
xcodebuild an xcframework from the fat static libs and the original iOS one, and add the header and module map to it under generated/MatrixSDKFFI.xcframework
cleanup and delete the generated files except the .xcframework and the swift sources (that aren't part of the framework)

Running the Xcode project

The Xcode project is meant to provide a simple example on how to integrate everything together but also a place to run unit and integration tests from.

It's pre-configured to link to the generated .xcframework and .swift files so successfully running the script first is necessary for it to compile.

It makes the compiled code available to swift by importing the C header through its bridging header.

Once all the generated components are available running it should be as easy as choosing a platform and clicking run.

Distribution

The generated framework and Swift code can be distributed and integrated directly but in order to make things simpler we bundle them together as a Swift package available TBD
