UISearchBar increases navigation bar height in iOS 11

Question

I have my UISearchBar being part of the navigation bar like:

 let searchBar = UISearchBar()
 //some more configuration to the search bar
 .....
         


        

Answer 1

I fixed this by added the constraint to viewDidAppear on the map view controller where the search bar is embedded

public override func viewDidAppear(_ animated: Bool) {
    if #available(iOS 11.0, *) {

        resultSearchController?.searchBar.heightAnchor.constraint(equalToConstant: 44).isActive = true
        // searchBar.heightAnchor.constraint(equalToConstant: 44).isActive = true
    }
}
