Can you elaborate?

Hey @andreamazz sorry not to reply sooner. The issue happening was my vc view would layout with the topLayoutGuide being zero & then once the navigation transition has completed - the guide would equal 64, resulting in my layout jumping all of a sudden.

I've not actually experienced this issue lately, so perhaps it has been resolved.

Glad to hear that 👍

@andreamazz this still seems to be an issue.
The toVC.topLayoutGuide.length == 20.0 during the animation, then equals 0.0 once completeTransition:YES is called.

I see. I'll try to reproduce the issue and get back to you.

@andreamazz seems to make a difference if the navigation bar is not translucent.

@andreamazz this is still an issue. In my case I show and hide the navigationBar during viewWillAppear() which might be causing this. Also doesnt happen when you hit the back button, only forward. And only happens to views dependent on topLayoutGuide

Edit: fixed it by commenting out [toVC.view setTransform:CGAffineTransformIdentity];
