NavBar overlaps Status Bar in iOS 13 Swift - ios

Question

In some devices as iPhone 7 and 8 the navigation bar overlaps status bar after do navigating, the parent view controller has status bar hidden but I show and hide it in viewWillAppear and viewWillDisappear respectively. I tested in iOS 12 and it works.
I am using prefersStatusBarHidden to hidden the status bar.

Update:
Here an example project: https://github.com/FranklinSamboni/NavBarTestSwfit.
It work fine in iOS 12 but with iOS 13 the navigation bar overlaps status bar in iPhone 7,8

Okay, I'm going to give one of those wishy-washy answers.
On the one hand, you've definitely found a new behavior in iOS 13. When you hide the status bar, the navigation bar shrinks. You could term this a bug in iOS 13...
On the other hand, it could be argued that what you are doing is wrong. If you have a navigation bar, you already cannot hide the status bar on a device without a bezel (iPhone X etc.), and now Apple seems to be assuming that if you have a navigation bar you won't hide the status bar at all. And that is a reasonable assumption, because it makes no sense to hide the status bar in portrait when there is a navigation bar, and especially in some children of the navigation controller but not others.
So you could file a bug report on this, but I don't think you'll get any joy from it. Apple is likely to reply that this is intended, or is at least a consequence of doing something they don't want to support. You have a navigation bar; allow the status bar to show.

I faced the same problem, after a few hours research, I found a not perfect but worked solution. Hope it will work for you.The code was written with Objective-C.
In viewDidAppear method of the secondViewController, hide statusBar first and show it at once.
Declare a member variable BOOL statusBarHidden in secondViewController
Implement prefersStatusBarHidden method from UIViewController
- (BOOL)prefersStatusBarHidden
{
return statusBarHidden;
}
Create a new method setStatusBarHidden
- (void)setStatusBarHidden:(BOOL)hidden
{
if (statusBarHidden != hidden)
{
statusBarHidden = hidden;
[self setNeedsStatusBarAppearanceUpdate];
}
}
Call setStatusBarHidden in viewDidAppear
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
[self setStatusBarHidden:YES];
[self setStatusBarHidden:NO];
}
