In iOS 10  and on newer iPhones  you can also use haptic API  This haptic feedback is softer than the AudioToolbox API   For your GAME OVER scenario  a heavy UI impact feedback should be suitable    UIImpactFeedbackGenerator style   heavy  impactOccurred     You could use the other haptic feedback styles

Swift 2 0  AudioToolbox now presents the kSystemSoundID Vibrate as a SystemSoundID type  so the code is  import AudioToolbox AudioServices  AudioServicesPlaySystemSound kSystemSoundID Vibrate  AudioServicesPlayAlertSound kSystemSoundID Vibrate   Instead of having to go thru the extra cast step  Props to  Dov  Original Answer  Swift 1 x  And  here s how you do it on Swift  in case you ran into the same trouble as I did  Link against AudioToolbox framework  Go to your project  select your target  build phases  Link Binary with Libraries  add the library there  Once that is completed  import AudioToolbox AudioServices     Use either of these AudioServicesPlaySystemSound SystemSoundID kSystemSoundID Vibrate   AudioServicesPlayAlertSound SystemSoundID kSystemSoundID Vibrate    The cheesy thing is that SystemSoundID is basically a typealias  fancy swift typedef  for a UInt32  and the kSystemSoundID Vibrate is a regular Int  The compiler gives you an error for trying to cast from Int to UInt32  but the error reads as  quot Cannot convert to SystemSoundID quot   which is confusing  Why didn t apple just make it a Swift enum is beyond me   aponomarenko s goes into the details  my answer is just for the Swifters out there

In my case I was using the AVCaptureSession  AudioToolbox was in project s build phases and it was imported but still didn t work  In order to make it work I stopped the session before vibration and continued on after that     import  lt AudioToolbox AudioToolbox h gt       property  nonatomic  AVCaptureSession  session      -  void vibratePhone       self session stopRunning        NSLog   vibratePhone       here        if   UIDevice currentDevice  model isEqualToString   iPhone                  AudioServicesPlaySystemSound  kSystemSoundID Vibrate              else               AudioServicesPlayAlertSound  kSystemSoundID Vibrate            self session startRunning

Important Note  Alert of Future Deprecation       As of iOS 9 0  the API functions description for    AudioServicesPlaySystemSound inSystemSoundID  SystemSoundID  AudioServicesPlayAlertSound inSystemSoundID  SystemSoundID    includes the following note   This function will be deprecated in a future release  Use AudioServicesPlayAlertSoundWithCompletion or   AudioServicesPlaySystemSoundWithCompletion instead       The right way to go will be using any of these two    AudioServicesPlayAlertSoundWithCompletion kSystemSoundID Vibrate  nil    or   AudioServicesPlayAlertSoundWithCompletion kSystemSoundID Vibrate       your callback code when the vibration is done  it may not vibrate in iPod  but this callback will be always called         remember to import AVFoundation

From  iPhone Tutorial  Better way to check capabilities of iOS devices    There are two seemingly similar functions that take a parameter kSystemSoundID Vibrate   1  AudioServicesPlayAlertSound kSystemSoundID Vibrate   2  AudioServicesPlaySystemSound kSystemSoundID Vibrate        Both of the functions vibrate the iPhone  But  when you use the first   function on devices that don   t support vibration  it plays a beep   sound  The second function  on the other hand  does nothing on   unsupported devices  So if you are going to vibrate the device   continuously  as an alert  common sense says  use function 2    First  add the AudioToolbox framework AudioToolbox framework to your target in Build Phases   Then  import this header file    import  lt AudioToolbox AudioServices h gt

In my travels I have found that if you try either of the following while you are recording audio  the device will not vibrate even if it is enabled   1  AudioServicesPlayAlertSound kSystemSoundID Vibrate   2  AudioServicesPlaySystemSound kSystemSoundID Vibrate     My method was called at a specific time in the measurement of the devices movements  I had to stop the recording and then restart it after the vibration had occurred   It looked like this   - void vibrate        recorder stop       AudioServicesPlaySystemSound  kSystemSoundID Vibrate        recorder start       recorder is an AVRecorder instance   Hope this helps others that have had the same problem before

I had great trouble with this for devices that had vibration turned off in some manner  but we needed it to work regardless  because it is critical to our application functioning  and since it is just an integer to a documented method call  it will pass validation  So I have tried some sounds that were outside of the well documented ones here  TUNER88 iOSSystemSoundsLibrary  I have then stumbled upon 1352  which is working regardless of the silent switch or the settings on the device  Settings- gt vibrate on ring  vibrate on silent    -  void vibratePhone         if   UIDevice currentDevice  model isEqualToString   iPhone                    AudioServicesPlaySystemSound  1352     works ALWAYS as of this post             else                     Not an iPhone  so doesn t have vibrate              play the less annoying tick noise or one of your own           AudioServicesPlayAlertSound  1105

For an iPhone 7 7 Plus or newer  use these three Haptic feedback APIs  Available APIs For notifications  let generator   UINotificationFeedbackGenerator   generator notificationOccured style   error   Available styles are  error   success  and  warning  Each has its own distinctive feel  From the docs   A concrete UIFeedbackGenerator subclass that creates haptics to communicate successes  failures  and warnings   For simple vibrations  let generator   UIImpactFeedbackGenerator style   medium  generator impactOccured    Available styles are  heavy   medium  and  light  These are simple vibrations with varying degrees of  quot hardness quot   From the docs   A concrete UIFeedbackGenerator subclass that creates haptics to simulate physical impacts  For when the user selected an item let generator   UISelectionFeedbackGenerator   generator selectionChanged    This is the least noticeable of all the haptics  and so is the most suitable for when haptics should not be taking over the app experience  From the docs   A concrete UIFeedbackGenerator subclass that creates haptics to indicate a change in selection   Notes There are a couple of things worth remembering when using these APIs  Note A You do not actually create the haptic  You request the system generate a haptic  The system will decide based on the below   If haptics are possible on the device  whether it has a Taptic Engine in this case  Whether the app may record audio  haptics do not generate during recording to prevent unwanted interference  Whether haptics are enabled in system Settings   Therefore  the system will silently ignore your request for a haptic if it is not possible  If this is due to an unsupported device  you could try this  func haptic            Get whether the device can generate haptics or not        If feedbackSupportLevel is nil  will assign 0     let feedbackSupportLevel   UIDevice current value forKey   quot  feedbackSupportLevel quot   as  Int    0      switch feedbackSupportLevel        case 2             2 means the device has a Taptic Engine            Put Taptic Engine code here  using the APIs explained above      case 1          1 means no Taptic Engine  but will support AudioToolbox        AudioToolbox code from the myriad of other answers       default     0            No haptic support            Do something else  like a beeping noise or LED flash instead of haptics        Substitute the comments in the switch-case statements  and this haptic generation code will be portable to other iOS devices  It will generate the highest level of haptic possible  Note B  Due to the fact that generating haptics is a hardware-level task  there may be latency between when you call the haptic-generation code  and when it actually happens  For this reason  the Taptic Engine APIs all have a prepare   method  to put it in a state of readiness  Using your Game Over example  You may know that the game is about to end  by the user having very low HP  or a dangerous monster being near them  If you don t generate a haptic within a few seconds  the Taptic Engine will go back into an idle state  to save battery life   In this case  preparing the Taptic Engine would create a higher-quality  more responsive experience  For example  let s say your app uses a pan gesture recogniser to change the portion of the world visible  You want a haptic to generate when the user  looks  round 360 degrees  Here is how you could use prepare     IBAction func userChangedViewablePortionOfWorld   gesture  UIPanGestureRecogniser          haptic   UIImpactFeedbackGenerator style   heavy       switch gesture state           case  began                 The user started dragging the screen              haptic prepare            case  changed                 The user trying to  look  in another direction                Code to change viewable portion of the virtual world              if virtualWorldViewpointDegreeMiddle   360 0                    haptic impactOccured                                  default              break
