It is done but my cancel button is not access

Answer 1

Swift 4:

Below 2 lines of code worked for me to show cancel button:

searchBar.setShowsCancelButton(true, animated: true)
searchBar.showsCancelButton = true

Calling inside searchBarTextDidBeginEditing() method will show cancel button after clicking on search bar.
