Use this library called IQKeyboardManager: https://github.com/hackiftekhar/IQKeyboardManager

Install pod file pod 'IQKeyboardManager’ . And in your app delegate 

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {


         IQKeyboardManager.shared.enable = true
         IQKeyboardManager.shared.enableAutoToolbar = true
        IQKeyboardManager.shared.toolbarDoneBarButtonItemText = "Done”

      return true
    }
}


You can change the following properties of IQKeyboardManager as well

       IQKeyboardManager.shared.overrideKeyboardAppearance = true
       IQKeyboardManager.shared.keyboardAppearance = .dark
       IQKeyboardManager.shared.toolbarBarTintColor = UIColor.cyan
       IQKeyboardManager.shared.toolbarDoneBarButtonItemImage = UIImage(named: "<#T##String#>")

       IQKeyboardManager.shared.shouldShowToolbarPlaceholder = false
        IQKeyboardManager.shared.placeholderFont = UIFont(name: "Times New Roman", size: 20.0)
        IQKeyboardManager.shared.shouldResignOnTouchOutside = true
        IQKeyboardManager.shared.shouldPlayInputClicks = true //default
