You're not the only person to run into this. rdar://problem/33635183 <rdar://problem/33635183> tracks the issue within Apple, and since it would need Xcode-side changes as well there's no point in having a report at bugs.swift.org <http://bugs.swift.org/>. I'm afraid we don't have a workaround right now other than what you've mentioned.
