Unchanged barTintColor UINavigationBar on iOS 13.4
I was having the same issue, what fixed it for me was this:
On the storyboard, for your Navigation Controller change the "Bar Tint" to its "Default" value, then on your code you can change it as you normally would.
// For the navigation bar navigationController?.navigationBar.barTintColor = .red // For the title let attributes = [NSAttributedString.Key.foregroundColor: UIColor.white ] navigationController?.navigationBar.titleTextAttributes = attributes
I have the code in viewDidLoad()
Oddly enough for me, it also fixed the issue I was having with the "Status Bar".
