Comment (by cjones051073):

 Thats is only an issue because of MPs insistence that the SDK must match
 the OS. Its not a requirement from the Apple/Xcode side, where as we have
 seen using a different one is fine, and actually what they promote (like
 right now where the latest macOS 10.14 Xcode uses 10.15 SDK).

 I was just pointing out, right now there is no Xcode for mac10.15 with an
 10.16 (or 11.0) SDK, so just removing the CLT completely would fix it.

 In the future, if (as I personally expect) Apple completely depreciates
 the CLT, then we will not be able to use this to solve the Xcode SDK
 issue, so we will need another way round it.
