I also ran into this problem a couple of times.. It's not the only issue. I put it down to how new the language is and how many non-critical issues they can fix. Swift 1.2 has been a massive improvement with incremental compiling and the SourceKit HUD not flickering in my face every few minutes. But still Xcode crashes frequently. With all the known problems considered, I still find that the advantage of using Swift far outweighs the small number of issues with it in its current version.
