The navigation bar just disappears on iOS 11 when our app is built with XCode 8.
Same code and Same app, without any modification, we use latest XCode 9 beta to build our app and install it on same device. The issue just goes away, the navigation bar is there.
I suspect there might be compatible issues with either iOS 11 or the XCode 8.
Can anyone help me ? Is there any way to submit a new build built with XCode 9 to app store before iOS 11 kicks off.
