The dividing line above the tab bar disappears as soon as I switch to a subcontroller and does not appear when I go back. In the current beta 4, the problem is still not fixed. Does anyone have the same problem? You could frame the tab bar but that's not a good solution. Thanks for the answer

I have developed an app that has worked well for years. My app uses a LaunchScreen.storyboard and supports all iPhone models 4.0" to 6.5". Some users have the problem that the iPhone7 (model 9,3) does not display the resolution correctly: UIDevice.current.modelName = iPhone9,3 -> ok UIScreen.main.bound = {{0, 0}, {320, 568}} -> should be {375, 667} So, 4.0" is scaled to 4.7", which is not correct. The users are using the latest operating system, but for the model iPhone9,1 the error is not yet known. All other resolutions work!
