Search bar hides on tap - ios

Question

Hi I have added search bar on UIView. When i run my code I can see my search bar, but as I tap inside search bar it hides itself, and when i tap again somewhere on screen it is visible.I am not getting this issue now.Please help.
var searchView:UIView = {
var search = UIView()
search.translatesAutoresizingMaskIntoConstraints = false
search.backgroundColor = UIColor.gray
return search
}()
lazy var searchController : UISearchController = {
var searchController = UISearchController(searchResultsController: nil)
//searchController.searchResultsUpdater = self
searchController.hidesNavigationBarDuringPresentation = false
searchController.searchBar.barTintColor = UIColor.gray
searchController.searchBar.layer.borderWidth = 1
searchController.searchBar.layer.borderColor = UIColor.gray.cgColor
//searchController.dimsBackgroundDuringPresentation = false
searchController.definesPresentationContext = true
searchController.searchBar.sizeToFit()
searchController.searchBar.translatesAutoresizingMaskIntoConstraints = false
return searchController
}()
func setUpView(){
view.addSubview(searchView)
searchView.addSubview(searchController.searchBar)
searchView.leftAnchor.constraint(equalTo: view.leftAnchor).isActive = true
searchView.rightAnchor.constraint(equalTo: view.rightAnchor).isActive = true
searchView.topAnchor.constraint(equalTo: view.topAnchor,constant:64).isActive = true
searchView.heightAnchor.constraint(equalToConstant: 65).isActive = true
searchController.searchBar.leftAnchor.constraint(equalTo: searchView.leftAnchor).isActive = true
searchController.searchBar.rightAnchor.constraint(equalTo: searchView.rightAnchor).isActive = true
searchController.searchBar.topAnchor.constraint(equalTo: searchView.topAnchor,constant:10).isActive = true
searchController.searchBar.widthAnchor.constraint(equalTo: searchView.widthAnchor).isActive = true
}
Also I have given this line in ViewDidLoad()-:
self.extendedLayoutIncludesOpaqueBars = true

I found that UISearchController's searchBar doesn't work well when it's set translatesAutoresizingMaskIntoConstraints = false. As a workaround, I embedded the search bar into a placeholder view with the desired constraints:
let searchBarPlaceholderView = UIView()
searchBarPlaceholderView.addSubview(searchController.searchBar)
searchBarPlaceholderView.translatesAutoresizingMaskIntoConstraints = false
searchBarPlaceholderView.heightAnchor.constraint(equalToConstant: 56).isActive = true
stackView.addArrangedSubview(searchBarPlaceholderView)
Notice, that the searchController.searchBar's translatesAutoresizingMaskIntoConstraints property is left true.
