iOS 13 - Right Bar Button Item goes offset in Modal Sheet presentation - swift

Question

I have this strange problem with iOS 13 and its new sheet cards style modal presentation.
From ViewController1 I modal present ViewController2 embedded in a NavigationController, and everything works fine.
From ViewController2, I then modal present ViewController3 embedded in a NavigationController, and I get the Right Bar Button offset.
Here is a video of the problem: does anybody have a fix?
Main View Controller
import UIKit
let vc1identifier = "vc1identifier"
let vc2identifier = "vc2identifier"
class ViewController: UIViewController {
#IBAction func tap1(_ sender: UIButton) {
if let navigation = self.storyboard?.instantiateViewController(withIdentifier: vc1identifier) as? UINavigationController,
let nextVC = navigation.contentViewController as? UnoViewController {
//self.navigationController?.pushViewController(nextVC, animated: true)
self.present(navigation, animated: true, completion: nil)
}
}
}
extension UIViewController {
var contentViewController: UIViewController {
if let navcon = self as? UINavigationController {
return navcon.visibleViewController!
} else {
return self
}
}
}
Second View Controller
import UIKit
class UnoViewController: UIViewController {
#IBOutlet weak var barButton: UIBarButtonItem!
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
barButton.title = "GotoVC2"
}
#IBAction func pressThis(_ sender: UIBarButtonItem) {
if let navigation = self.storyboard?.instantiateViewController(withIdentifier: vc2identifier) as? UINavigationController,
let nextVC = navigation.contentViewController as? DueViewController {
self.present(navigation, animated: true, completion: nil)
}
}
}

I came across the same issue.
Solution is easy, you just need to tell navigationbar it needs layout like this
override public func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
if #available(iOS 13.0, *) {
navigationController?.navigationBar.setNeedsLayout()
}
}
