Minor issue here, (none the less annoying) I use three finger drag a lot - but doing so to move / arrange working windows, Xcode 7 (all versions) always, consistently closes with "Xcode quit unexpectedly ". Havent done much research on it, but was hoping someone else has come across this. Issue has been persistent since first beta of Xcode 7. Was hoping it was just a beta issue, but issue persists in full GM. Reinstalled Xcode twice and issue persists. Again, not major problem - just hoping I'm not the only dev to see this in the wild.
