Hi,
I have a piece of code which did custom unwind in iOS 8. Works fine iOS 8 but does not work in iOS 9. I know some APIs have been deprecated but existing code should still work. Is it known issue? Is there a work around?
New way of unwinding at WWDC builds upon modal presentation and does not work for the unwind for custom.
Thanks,
I've only found your inquiry after posting my own similar one https://forums.developer.apple.com/message/22460#22460 Have you found an alternative yet? I've not begun any porting to iOS 9.0 as of yet, but looking ahead have yet to discover anything (or theory why it was being deprecated for that matter).
I ran into a similar problem. I found a way to get custom unwind segues to work in both iOS 8 and iOS 9: http://stackoverflow.com/questions/32707698/custom-unwind-segue-for-ios-8-and-ios-9
