    Think you need to work on safe area that is introduced on xcode 9 Here you may find some clue https://stackoverflow.com/questions/44492404/safe-area-of-xcode-9 – dip Oct 05 '17 at 10:09

If the navigation icons are not showing, but the interaction is still exists and works properly, it seems, that the problem is with image of the BarButtonItem. You can do next:

1) Try to set a system icon for BarButtonItem
2) Look at assets and fill all three resolutions (1, @2x, @3x)
3) Check the color of BarButtonItem
4) Check View Hierarchy

This issue happened to me and it was related to the ViewController segue properties. The segue kind was set to "Show Detail(e.g. Replace)" and changing it to Show(e.g. Push) did the trick. This is very weird because it used to work well on previous versions of Xcode but not on Xcode 9.3

Hope that helps!
