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!

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
