The original radar that this one was duped to, 32990161, has now been closed. Confirmed fixed in Xcode 9 beta 6.

Closed as a duplicate of 32990161, which as of this writing is still open, but the issue appears to be fixed in Xcode 9 beta 4.

I posted the wrong Xcode build number before (got too clever with a script I wrote to copy the Xcode version number for me to save time), but I have re-tested in Xcode 9 beta 3, and can confirm that it is still broken as I previously reported.
