Get Started

Playback the youtube video.

import YoutubeKit

final class VideoPlayerController: UIViewController {

    private var player: YTSwiftyPlayer!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // Create a new player
        player = YTSwiftyPlayer(
                    frame: CGRect(x: 0, y: 0, width: 640, height: 480),
                    playerVars: [.videoID("videoID-abcde")])

        // Enable auto playback when video is loaded
        player.autoplay = true
        
        // Set player view.
        view = player

        // Set delegate for detect callback information from the player.
        player.delegate = self
        
        // Load the video.
        player.loadPlayer()
    }
}

YTSwiftyPlayerDelegate

YTSwiftyPlayerDelegate supports folowing delegate methods.

func playerReady(_ player: YTSwiftyPlayer)
func player(_ player: YTSwiftyPlayer, didUpdateCurrentTime currentTime: Double)
func player(_ player: YTSwiftyPlayer, didChangeState state: YTSwiftyPlayerState)
func player(_ player: YTSwiftyPlayer, didChangePlaybackRate playbackRate: Double)
func player(_ player: YTSwiftyPlayer, didReceiveError error: YTSwiftyPlayerError)
func player(_ player: YTSwiftyPlayer, didChangeQuality quality: YTSwiftyVideoQuality) 
func apiDidChange(_ player: YTSwiftyPlayer)    
func youtubeIframeAPIReady(_ player: YTSwiftyPlayer)    
func youtubeIframeAPIFailedToLoad(_ player: YTSwiftyPlayer)

Call IFrame API during playback.

// Pause the video.
player.pauseVideo()

// Seek after 15 seconds.
player.seek(to: 15, allowSeekAhead: true)

// Set a mute.
player.mute()

// Load another video.
player.loadVideo(videoID: "abcde")

Get video information using YoutubeDataAPI

First, Get API key from Here.

Next, add this code in your AppDelegate.

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    // Set your API key here
    YoutubeKit.shared.setAPIKey("Your API key")

    return true
}

And then you can use YoutubeDataAPI request like this.

// Get youtube chart ranking
let request = VideoListRequest(part: [.id, .statistics], filter: .chart)

// Send a request.
ApiSession.shared.send(request) { result in
    switch result {
    case .success(let response):
        print(response)
    case .failed(let error):
        print(error)
    }
}

Example of response here.

VideoList(items: [YoutubeKit.Video(etag: "\"A8kisgyDEbllhHF9ooXPFFrkc/nR6_A9oyIoLTJuucY_UXeasjYNU\"",
kind: "youtube#video",
id: "jeiDjeJgF0",
contentDetails: nil,
statistics: Optional(YoutubeKit.Statistics.VideoList(dislikeCount: "1631", likeCount: "60307", commentCount: Optional("8675"), favoriteCount: "0", viewCount: "1259046")),
snippet: nil,
status: nil),
etag: "\"J67fSnfblalhHF0foXPiFFrkc/TZGPJdE22-LilSv4-3VNoPw1cS4\"",
kind: "youtube#videoListResponse",
pageInfo: YoutubeKit.PageInfo(resultsPerPage: 5, totalResults: 200))

Fetch the next page (Pagination)

var nextPageToken: String?
...

// Send some request
ApiSession.shared.send(request) { [weak self] result in
    switch result {
    case .success(let response):
    
        // Save nextPageToken
        self?.nextPage = response.nextPageToken
    case .failed(let error):
        print(error)
    }
}
...

// Set nextPageToken
let request = VideoListRequest(part: [.id], filter: .chart, nextPageToken: nextPageToken)

Authorization Request

If you want authorized request such as a getting your activity in Youtube, you set your access token before sending a request. To use GoogleSignIn, you can easily get your access token. pod 'GoogleSignIn'

First, add this code in your AppDelegate.

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    // Set your access token for autheticate request
    YoutubeKit.shared.setAccessToken("Your access token")

    return true
}

And then you can use request requiring authorization, this is an example to get your Youtube activity.

// Get your Youtube activity
let request = ActivityListRequest(part: [.snippet], filter: .mine(true))

// Send a request.
ApiSession.shared.send(request) { result in
    switch result {
    case .success(let video):
        print(video)
    case .failed(let error):
        print(error)
    }
}
