Xcode and migration aren't part of the Swift open source project, but this is something I've heard other people complaining about. Can you please file a Radar if you haven't already (bugreport.apple.com) and include your project file, then send me the bug number? (For this particular issue, I think we can get away with just the xcodeproj rather than the entire project sources that we'd usually need.)
