Prompt to update `DEVELOPER_DIR` for macOS toolchain selection #938

Open matthewbastien opened 4 days ago

This updates the toolchain selection workflow to also set the DEVELOPER_DIR environment variable on macOS. This will be done automatically if the user selected an Xcode toolchain. However, they will be prompted to select a developer directory if they select a public Swift toolchain and there is more than one Xcode application installed on their system.

Linux and Windows toolchain selection is unaffected by this change.

Issue: #911

We need to make it clear why you need the DEVELOPER_DIR, as it is not clear to me what the swift downloaded toolchains use from Xcode. @dschaefer2 perhaps you can answer that

The macOS SDK? Lots of good stuff in there :).
