Answer 1

I've solved the issue, but it required a hard reset.
Some said it was because I installed XCode outside of the App Store, or because the simluator was buggy, or because XCode was pointing at the wrong version of the Simulator, or a resoruce was missing a target membership, or whatever.  I tried all of that.
I downloaded XCode from the App Store, re-installed the Simulators, and still no luck.  So I just rolled back my repository to an earlier date, and lost some work in the process.  Not much though, because I always commit little and often.
Since ever starting to use storyboards back in 2011, I have always committed little AND OFTEN.  Storyboard are fragile.
