The same program run on the iOS10 simulator and the iOS11 simulator renders very differently. Is there a good summary of the non-back-compatible deltas, or how to have one SceneKit program generate the same output on the different iOS versions?

As of right now it seems you can't read back a nodes euler angles (only get zeroes for pitch, yaw & roll). So if you try to rotate your node based on its initial euler angles it will be wrong.

That would explain the difference in orientation, as well as a few other anomalies I'm seeing but didn't ask about. Thanks. By the way, how did you discover this?! – Ramsay Consulting Aug 05 '17 at 14:50

I kind of had the same problem, so I printed out the angle values, and on iOS 8-10 you can read out the initial angles, on iOS 11 beta you get zeroes. – F.Ahlström Aug 07 '17 at 09:09
