I'm trying to dump the AST for all the Swift files in an Xcode project. I think I've mostly figured it out, but want to make sure I'm constructing the swiftc target correctly. Right now, this is how I'm doing it based on some guesswork. I get this indirect property:

   eval CUR_TARGET_NAME='$'$DEPLOYMENT_TARGET_SETTING_NAME

and then construct the target like so:

   ${arch}-apple-${SWIFT_PLATFORM_TARGET_PREFIX}${CUR_TARGET_NAME}

Will that reliably give me an appropriate target? And will it work for both iOS and OS X?

Thanks.

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.

Ahh, that is an awesome suggestion! I'll try that.

Thanks!
