Incorrect view of images when changing orientation to portrait/horizontal on iOS

[VladimirAmiorkov]

When you rotate the phone/simulator on iOS you get an error [App] if we're in the real pre-commit handler we can't actually add any new fences due to CA restriction

and the "state" of the image-swipe is broken (it is between two images).

Evnironment

Tested with

• iOS - 10.3

How to reproduce

1. Run the demo app on iOS, I used demo-ng
2. Swipe left to get to the next image (the bears)
3. Rotate Right (cmd + Right arrow). Now you see black screen (you are between the images, like a "mid swipe")
4. Rotate Left (cmd + Left arrow). Now you can clearly see the images are stuck in mid swipe
