Make the iPhone vibrate with kSystemSoundID_Vibrate

The following code was built with Xcode 7.2.1 (Swift 2.1.1).

Create a new Single View Application project in Xcode and modify ViewController.swift as:

import UIKit

import AudioToolbox

class ViewController: UIViewController {

    

    override func viewDidLoad() {

        super.viewDidLoad()

        

        //Buttons

        let button1 : UIButton!

        button1 = UIButton(frame: CGRectMake(0, 0, 300, 30))

        button1.center = CGPointMake(view.center.x, 150)

        button1.setTitle("Vibrate Alert", forState: UIControlState.Normal)

        button1.setTitleColor(UIColor.blueColor(), forState: UIControlState.Normal)

        button1.setTitleColor(UIColor.cyanColor(), forState: UIControlState.Highlighted)

        button1.addTarget(self, action: "btn1Pressed:", forControlEvents: UIControlEvents.TouchUpInside)

        view.addSubview(button1)

        

        let button2 : UIButton!

        button2 = UIButton(frame: CGRectMake(0, 0, 300, 30))

        button2.center = CGPointMake(view.center.x, 300)

        button2.setTitle("Vibrate System", forState: UIControlState.Normal)

        button2.setTitleColor(UIColor.blueColor(), forState: UIControlState.Normal)

        button2.setTitleColor(UIColor.cyanColor(), forState: UIControlState.Highlighted)

        button2.addTarget(self, action: "btn2Pressed:", forControlEvents: UIControlEvents.TouchUpInside)

        view.addSubview(button2)

    }

    

    func btn1Pressed(sender: UIButton) {

        AudioServicesPlayAlertSoundWithCompletion(SystemSoundID(kSystemSoundID_Vibrate), nil)

        //AudioServicesPlayAlertSound(SystemSoundID(kSystemSoundID_Vibrate))

    }

    

    func btn2Pressed(sender: UIButton) {

        AudioServicesPlaySystemSoundWithCompletion(SystemSoundID(kSystemSoundID_Vibrate), nil)

        //AudioServicesPlaySystemSound(SystemSoundID(kSystemSoundID_Vibrate))

    }

    

    override func didReceiveMemoryWarning() {

        super.didReceiveMemoryWarning()

    }

}

Result with an iPhone 5:

The iPhone vibrates when pressing either of the buttons.

Result with an iPad 3rd generation:

The iPad neither vibrates nor beeps when pressing either of the buttons.

AVCaptureTorchMode - Flashlight / Torch function

1. Drag a button to the storyboard. Make the text as "OFF".

2. Control-drag the button to ViewController.swift and make it an IBAction:

    @IBAction func myButton(sender: AnyObject) {

    }

3. Complete the code as below:

import UIKit

import AVFoundation

class ViewController: UIViewController {

    @IBAction func myButton(sender: AnyObject) {

        

        let myDevice = AVCaptureDevice.defaultDeviceWithMediaType(AVMediaTypeVideo)

        

        if (myDevice.hasTorch) {

            myDevice.lockForConfiguration(nil)

            if (sender.titleLabel!?.text == "ON")

            {

                myDevice.torchMode = AVCaptureTorchMode.Off

                sender.setTitle("OFF", forState:  UIControlState.Normal);

            }

            else

            {

                myDevice.torchMode = AVCaptureTorchMode.On

                sender.setTitle("ON", forState:  UIControlState.Normal);

            }

            myDevice.unlockForConfiguration()

        } else {

            let alertView = UIAlertView()

            alertView.message = "No Flash Detected!"

            alertView.addButtonWithTitle("OK")

            alertView.show()

        }

    }

    override func viewDidLoad() {

        super.viewDidLoad()

        // Do any additional setup after loading the view, typically from a nib.

    }
