How to play a local video with Swift?

Sure you can use Swift!

1. Adding the video file

Add the video (lets call it video.m4v) to your Xcode project

2. Checking your video is into the Bundle

Open the Project Navigator cmd + 1

Then select your project root > your Target > Build Phases > Copy Bundle Resources.

Your video MUST be here. If it's not, then you should add it using the plus button

3. Code

Open your View Controller and write this code.

import UIKitimport AVKitimport AVFoundationclass ViewController: UIViewController {    override func viewDidAppear(_ animated: Bool) {        super.viewDidAppear(animated)        playVideo()    }    private func playVideo() {        guard let path = Bundle.main.path(forResource: "video", ofType:"m4v") else {            debugPrint("video.m4v not found")            return        }        let player = AVPlayer(url: URL(fileURLWithPath: path))        let playerController = AVPlayerViewController()        playerController.player = player        present(playerController, animated: true) {            player.play()        }    }}

another Swift 3 Example. The provided solution did not work for me.

private func playVideo(from file:String) {    let file = file.components(separatedBy: ".")    guard let path = Bundle.main.path(forResource: file[0], ofType:file[1]) else {        debugPrint( "\(file.joined(separator: ".")) not found")        return    }    let player = AVPlayer(url: URL(fileURLWithPath: path))    let playerLayer = AVPlayerLayer(player: player)    playerLayer.frame = self.view.bounds    self.view.layer.addSublayer(playerLayer)    player.play()}

useage:

playVideo(from: "video.extension")

Note:Check Copy Bundle Resources under Build Phases to ensure that the video is available to the Project.

U can setup AVPlayer in another way, that open for u full customization of your video Player screen

Swift 2.3

1. Create UIView subclass for playing video (basically u can use any UIView object and only needed is AVPlayerLayer. I setup in this way because it much clearer for me)

   import AVFoundationimport UIKitclass PlayerView: UIView {override class func layerClass() -> AnyClass {    return AVPlayerLayer.self}var player:AVPlayer? {    set {        if let layer = layer as? AVPlayerLayer {            layer.player = player        }    }    get {        if let layer = layer as? AVPlayerLayer {            return layer.player        } else {            return nil        }    }}}

2. Setup your player

   import AVFoundationimport Foundationprotocol VideoPlayerDelegate {    func downloadedProgress(progress:Double)    func readyToPlay()    func didUpdateProgress(progress:Double)    func didFinishPlayItem()    func didFailPlayToEnd()}let videoContext:UnsafeMutablePointer<Void> = nilclass VideoPlayer : NSObject {    private var assetPlayer:AVPlayer?    private var playerItem:AVPlayerItem?    private var urlAsset:AVURLAsset?    private var videoOutput:AVPlayerItemVideoOutput?    private var assetDuration:Double = 0    private var playerView:PlayerView?    private var autoRepeatPlay:Bool = true    private var autoPlay:Bool = true    var delegate:VideoPlayerDelegate?    var playerRate:Float = 1 {        didSet {            if let player = assetPlayer {                player.rate = playerRate > 0 ? playerRate : 0.0            }        }    }    var volume:Float = 1.0 {        didSet {            if let player = assetPlayer {                player.volume = volume > 0 ? volume : 0.0            }        }    }    // MARK: - Init    convenience init(urlAsset:NSURL, view:PlayerView, startAutoPlay:Bool = true, repeatAfterEnd:Bool = true) {        self.init()        playerView = view        autoPlay = startAutoPlay        autoRepeatPlay = repeatAfterEnd        if let playView = playerView, let playerLayer = playView.layer as? AVPlayerLayer {            playerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill        }        initialSetupWithURL(urlAsset)        prepareToPlay()    }    override init() {        super.init()    }    // MARK: - Public    func isPlaying() -> Bool {        if let player = assetPlayer {            return player.rate > 0        } else {            return false        }    }    func seekToPosition(seconds:Float64) {        if let player = assetPlayer {            pause()            if let timeScale = player.currentItem?.asset.duration.timescale {                player.seekToTime(CMTimeMakeWithSeconds(seconds, timeScale), completionHandler: { (complete) in                    self.play()                })            }        }    }    func pause() {        if let player = assetPlayer {            player.pause()        }    }    func play() {        if let player = assetPlayer {            if (player.currentItem?.status == .ReadyToPlay) {                player.play()                player.rate = playerRate            }        }    }    func cleanUp() {        if let item = playerItem {            item.removeObserver(self, forKeyPath: "status")            item.removeObserver(self, forKeyPath: "loadedTimeRanges")        }        NSNotificationCenter.defaultCenter().removeObserver(self)        assetPlayer = nil        playerItem = nil        urlAsset = nil    }    // MARK: - Private    private func prepareToPlay() {        let keys = ["tracks"]        if let asset = urlAsset {            asset.loadValuesAsynchronouslyForKeys(keys, completionHandler: {                dispatch_async(dispatch_get_main_queue(), {                    self.startLoading()                })            })        }    }    private func startLoading(){        var error:NSError?        guard let asset = urlAsset else {return}        let status:AVKeyValueStatus = asset.statusOfValueForKey("tracks", error: &error)        if status == AVKeyValueStatus.Loaded {            assetDuration = CMTimeGetSeconds(asset.duration)            let videoOutputOptions = [kCVPixelBufferPixelFormatTypeKey as String : Int(kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange)]            videoOutput = AVPlayerItemVideoOutput(pixelBufferAttributes: videoOutputOptions)            playerItem = AVPlayerItem(asset: asset)            if let item = playerItem {                item.addObserver(self, forKeyPath: "status", options: .Initial, context: videoContext)                item.addObserver(self, forKeyPath: "loadedTimeRanges", options: [.New, .Old], context: videoContext)                NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(playerItemDidReachEnd), name: AVPlayerItemDidPlayToEndTimeNotification, object: nil)                NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(didFailedToPlayToEnd), name: AVPlayerItemFailedToPlayToEndTimeNotification, object: nil)                if let output = videoOutput {                    item.addOutput(output)                    item.audioTimePitchAlgorithm = AVAudioTimePitchAlgorithmVarispeed                    assetPlayer = AVPlayer(playerItem: item)                    if let player = assetPlayer {                        player.rate = playerRate                    }                    addPeriodicalObserver()                    if let playView = playerView, let layer = playView.layer as?

3. Usage:

assume u have view

@IBOutlet private weak var playerView: PlayerView!private var videoPlayer:VideoPlayer?

and in viewDidLoad()

    private func preparePlayer() {        if let filePath = NSBundle.mainBundle().pathForResource("intro", ofType: "m4v") {            let fileURL = NSURL(fileURLWithPath: filePath)            videoPlayer = VideoPlayer(urlAsset: fileURL, view: playerView)            if let player = videoPlayer {                player.playerRate = 0.67            }        }    }
