[swift-users] Divining the proper swiftc target for an Xcode project

[Jordan Rose]

The Swift target triples are the same as LLVM's target triples. Your logic matches what Xcode's currently doing to invoke Swift (and I assume that's where you got it from :-) ), but there's no guarantee that it will continue to work. If you really want something stable-ish, I'd suggest doing a -dry-run xcodebuild and extracting the swiftc lines from that.
