I have several views that are presented modally. Using iOS 13 & Xcode 11 (b7), for the ones where I have a view controller embedded in a navigation controller, the presenting view controller is visible between the navigation bar & the view navigation controller stack. Don't have this problem with Xcode 10 & iOS 12.
Does anyone know why this is happening & how to fix it?
Solution to this wound up being pretty easy. All I needed to do was add an explicit background color to the Navigation Controller's Navigation Bar in my storyboard.
In Xcode 11, the "default" color for the background is now a black box with a red line through it, whereas in previous versions it was a white box with a red line. I mistakenly took this color to mean that I had previously set a color there when I in fact had not.
