Method: AppleFrameworks::XCFramework#build_using_xcode

Defined in:
lib/apple_frameworks/xcframework.rb

#build_using_xcode ⇒ Object

Uses the ‘xcodebuild -create-xcframework` command to create the XCFramework.

This will require Xcode and its command line tools to be installed.

Xcode has a couple of notable annoyances:

  • Fat binaries with multiple platforms (e.g. a single binary containing iOS simulator x64 and iOS arm64) are not supported.

  • To include multiple architectures of the same platform (e.g. iOS simulator x64 and arm64), they first need to be combined as a Fat binary.
