Updated for Swift 3:

if you are used UITapGestureRecognizer in your code :- # Swift 3 use below lines of code:

extension YourViewController{
    func hideKeyboardWhenTappedAround() {
        let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(YourViewController.dismissKeyboard))
        view.addGestureRecognizer(tap)
        tap.cancelsTouchesInView = false
    }

    func dismissKeyboard() {
        view.endEditing(true)
    }
}

How to called:- In ViewDidLoad()

self.hideKeyboardWhenTappedAround()
