No Xcode 8 CLT for El Capitan

[Jack Howarth]

You probably also want to note...

On OS X El Capitan, running Swift from the command line can fail if
any Command Line Tools (OS X 10.11) package is installed on the
system. (28234754)

Workaround: Execute Swift through from the command line using xcrun, .
Choose the macOS SDK using the -sdk. For example, the following
command compiles the file main.swift:

xcrun -sdk macosx swiftc main.swift

also from the Known Command Line Tools issues.

ps Wonder what you have to do to get Apple to unlock your Apple
developer account from moderation. I am still flummoxed that they
locked my account for reposting something from the release notes.
