[swift-dev] Change of requirements to build swift?

Hi, Guillaume. The master branch always builds with the latest publicly released Xcode beta; building with older Xcodes is not officially supported. However, the primary dependency here is building the overlays (in stdlib/public/SDK), which are closely coupled with the Apple SDKs; if you’re seeing issues, it may be possible to either disable or fix the problematic overlays.

The host OS should not affect the build except that (a) very old OSs may not be able to run all the tests, and (b) newer Xcodes drop support for older OSs.

Sorry for the inconvenience,
