I'm using a Show (Push) Segue to bring up a new ViewController for my app: Supernova  (com.arjan.iphone.supernova)

On iOS 8, it works and gives my back button in the NavigationBar without any additional work.

But on iOS 9 (beta 3): It brings up the ViewController without the Back button. It also brings up the VC from the bottom which is how 'Present Modally' Segues work.

This is a problem for my app because the user is unable to go back to the previous screen since there is no Back button.

Screenshots attached which show iOS 8 back buttons and iOS 9 missing back button.

I also tried to manually add back buttons to the navigation controller but it still didn't show up.

Steps to Reproduce:
1. Download App: "Supernova: Group Photo Sharing" (link:
2. Log in
3. Click on 'Sample Album'
4. The Navigation Bar shows but Back button is missing.

Expected Results:
Navigation Bar should have Back Button.

Actual Results:
 The Navigation Bar shows but Back button is missing.

iOS 9.0 Beta 3 [13A4293g)
