LargeTitles UIScrollView does not support multiple observers implementing _scrollViewWillEndDraggingWithVelocity:targetContentOffset

Question

I have implemented large titles in my app with the following code:

if #available(iOS 11.0, *) {
            navigationController?.navigationBar.prefersLargeTitle         


        

Answer 1

I've the same problem and I fixed it by removing this line from AppDelegate:

UINavigationBar.appearance().prefersLargeTitles = true

and handle prefersLargeTitles inside viewDidLoad in certain UIViewController
