Add rudimentary support for the Apple Swift language with Xcode

Allow the `Swift` language to be enabled with the Xcode generator for
Xcode >= 6.1.  Reject it on other generators and with older Xcode
versions.  Since Apple is the only vendor implementing the language
right now, the compiler id can be just `Apple`.
