Getting Start:-
Let’s now start an your Application design;
1.     Open your xcode
2.     Create a new xcode project
3.     Chose a single View Application then
4.     Click on next button then,
5.     Give the product name as you like then
6.     Click again next button then,
7.     Save in your directory and click on the create button
8.     Now ready your empty project then,
9.     Select you device that you want run your project

Now goto the project navigator and select the main.Storyboard from the project navigator
·        Now select your View Controller and goto the editor menu select the navigation controller you will see that add a navigation controller in your main.stroyboard
·        Then now select the navigation controller you will seen that your navigation controller automatically make a initial view controller
·        Let’s come on the design your view controller select the object library and search a UIButton  then drag  a four uibutton  like this

Now drag four UIButon in the view controller you can seen

Now come on the change the text name of our button in the view controller we have two option change the name of the view the button
1.     Select the button and double your button text will come on edit mode.
2.     If you have second one  option select the button and goto the attribute inspector change the text name of your button

Change the button name with as you need like this

You see on the scren shot text name button change with AudioPlayer 
·        Now ready your design for the click button paly the audio video and repeat the song and stop the song

·        Now goto the project navigator select the view controller

import AVFoundation
//MARK:- add this line below the import uikit

//Mark:- now make function to call audioplayer

func playAudio()
// get random number for sound from the array
let intRandomNum = Int(arc4random_uniform(UInt32(arrAudio.count)))
// set URL of the sound
let soundURL = URL(fileURLWithPath: Bundle.main.path(forResource: arrAudio[intRandomNum], ofType: "wav")!)
   audioPlayer = try AVAudioPlayer(contentsOf: soundURL as URL)
   audioPlayer.delegate = self
// check if audioPlayer is prepared to play audio
if (audioPlayer.prepareToPlay()){
        catch(let error)

·        Now make object for audioPlayer with AVAudioPlayer() like this:

var audioPlayer = AVAudioPlayer()

// Mark:- now add delegate method
class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate, AVAudioPlayerDelegate
// Mark now make to function for stop Audio

func stopAudio()
        btnPlayAudioRepeatedly.isEnabled = true
        btnStopAudio.isEnabled = false
        playAudioRepeatedly = false
 // mark function for get video from the iphone and directory

func getVideos()
    let imagePickerController = UIImagePickerController()
imagePickerController.sourceType = .savedPhotosAlbum
imagePickerController.mediaTypes = [kUTTypeMovie as String]
imagePickerController.delegate = self
self.present(imagePickerController, animated: true, completion: nil)

// Now created an object for Boolean value

var playAudioRepeatedly = true

// mark:- create array for playAudio data from your mobile and simulator

let arrAudio: [String] = ["chime_bell_ding", "music_marimba_chord", "pop_drip"]

//now make two @iboutlet weak var those create a memory for outlet:-

@IBOutlet weak var btnPlayAudioRepeatedly: UIButton!
@IBOutlet weak var btnStopAudio: UIButton!

//MARK: - AVAudioPlayerDelegate Methods

func audioPlayerDidFinishPlaying(_ player: AVAudioPlayer, successfully flag: Bool)
        if (playAudioRepeatedly)

·       Now goto the object library and drag an AVKItPlayer View Controller

Now goto the project navigator and select the main project directory click on right open a list select the new file like this

Now create a new swift class that class will be cocoa touch class like this and click on the next button and give the class name VideoPlayerViewController and subclass should be AVPlayerViewController like this

After click next button open new window like seen this

Now create a new swift class with name will be VideoPlayerViewController import with these two libraries
import AVKit
import AVFoundation

//Mark: - now add a notification function for reachEndnotificationHandler

func playerDidReachEndNotificationHandler(notification: Notification)
//Mark: - this function use for load video
    func loadVideo(){
        videoPlayer = AVPlayer(url: videoURL)
        let playerVc = AVPlayerViewController()
        playerVc.player = videoPlayer
        NotificationCenter.default.addObserver(self, selector: #selector(playerDidReachEndNotificationHandler(notification:)), name: Notification.Name.AVPlayerItemDidPlayToEndTime, object: videoPlayer.currentItem)
        self.present(playerVc, animated: true)
now do a thing that goto the click on main.storyboard select the AVKit player view controller and select the identity inspector give the class name VideoPlayerViewController and copy this class name paste the storyboard id box and Check the use storyboarb id This will work for the identifier

  Now once again goto the view controller and create a uiimageaPickerControllerDelegate method

// MARK: - UIImagePickerControllerDelegate Methods
 func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]){
self.dismiss(animated: true, completion: nil)
let videoPlayerViewController = self.storyboard!.instantiateViewController(withIdentifier: "VideoPlayerViewController") as! VideoPlayerViewController videoPlayerViewController.videoURL = info[UIImagePickerControllerMediaURL] as? URL as URL!
self.navigationController!.pushViewController(videoPlayerViewController, animated: true)

now last one thing add @ibaction for all button in the view controller 
make an action for every button  and add functionality

//MARK: - Action Methods
 @IBAction func btnPlayAudioTapped(sender: AnyObject)
@IBAction func btnPlayVideoTapped(sender: AnyObject)
@IBAction func btnPlayAudioRepeatedlyTapped(sender: AnyObject)
        btnPlayAudioRepeatedly.isEnabled = false
        btnStopAudio.isEnabled = true
        playAudioRepeatedly = false
@IBAction func btnStopAudioTapped(sender: AnyObject)

Now one important thing add a string library into a plist  because if not add this stirng  library application give the run time error
Select the info plist in the project navigator click on the add button  like this

and tap on the pulse button select the srting library this
