Summary:
My iOS app (all objc), when run in Xcode8b2, spews an incredible amount of internal toolkit to the console.
See attached movie.
See attached text file with the outut
See attached xcode project for the product.

There's a pretty incredible "Xcode loses its mind and can't find any simulators" in the middle - I'll file another radar for that.

Steps to Reproduce:
1. ran my app
2. it runs

Expected Results:
3. relatively calm console with app caveman debugging

Actual Results:
3. quite the torrent of information.

Regression:
No extra console output in Xcode 7.3.  I don't know if I have any magic debug env vars or flags set, but I can't see anything in the scheme (I browse the scheme in the video around 2:30.

This seems to be the only app that triggers it.
