    # Github Actions' machines do in fact have recent versions of Xcode,
    # but you may have to explicitly switch to them.  We explicitly want
    # to use Xcode 11, so we use xcode-select to switch to it.

      run: sudo xcode-select --switch /Applications/Xcode_11.1.app
    # Since we want to be running our tests from Xcode, we need to
    # generate an .xcodeproj file.  Luckly, Swift Package Manager has
    # build in functionality to do so.

    # Finally, we invoke xcodebuild to run the tests on an iPhone 11
    # simulator.
