Ok, I can reproduce this on my iPad Air. Previously, I had Firefox already running that's why I couldn't hit this crash.

Just hit it on iOS 9.1

I don't have a device. Can you somehow get a crash log or trace or even console log out of this?

We need more details.

Turns out willTransitionToTraitCollection gets called BEFORE viewDidLoad in this case... Seems very strange.
