App Transport Security Settings

To support HTTP hosted : add the Boolean type Value to YES for NSAllowsArbitraryLoads in app's info.plist file.

Usage

• To run the example project, download or clone the repo.
• MULTITASKING RECOMMANDATIONS : Perform and prepare your app to avoid memory leaks and others with Instruments!
• IN USE OF AVPictureInPictureController , use : AVPictureInPictureController.isPictureInPictureSupported() to get devices capability

Example Code!

• Set your AVPlayer, AVPlayerViewController or AVPlayerLayer in one controller to play video!
• Add AVKit + AVFoundation Frameworks

import AVKit
import AVFoundation

• Set AVAudioSession in didFinishLaunchingWithOptions UIApplication Delegate

/// REQUIRED FOR PIP!!!
/// After active Audio/Airplay Background Mode in General Settings.
/// Setup Audio Session for Picture in Picture
let audioSession = AVAudioSession.sharedInstance()

do {
    try audioSession.setCategory(AVAudioSessionCategoryPlayback)
}
catch {
    print("handle errors setting Audio session Category")
}

• Delegate your controller with AVPlayerViewControllerDelegate Extension

extension ViewController : AVPlayerViewControllerDelegate {

    /// playerViewController will start PIP
    func playerViewControllerWillStartPictureInPicture(playerViewController: AVPlayerViewController) {
        print("PIP will start")
    }

    /// playerViewController did start PIP
    func playerViewControllerDidStartPictureInPicture(playerViewController: AVPlayerViewController) {
        print("PIP did start")
    }

    /// playerViewController will stop PIP
    func playerViewControllerWillStopPictureInPicture(playerViewController: AVPlayerViewController) {
        print("PIP will stop")
    }

    /// playerViewController did stop PIP
    func playerViewControllerDidStopPictureInPicture(playerViewController: AVPlayerViewController) {
        print("PIP did stop")
    }

    /// playerViewController failed to start PIP
    func playerViewController(playerViewController: AVPlayerViewController, failedToStartPictureInPictureWithError error: NSError) {
        print("PIP Error : \(error.localizedDescription)")
    }

    /// playerViewController automatically dismiss at PIP Start.
    func playerViewControllerShouldAutomaticallyDismissAtPictureInPictureStart(playerViewController: AVPlayerViewController) -> Bool {
        return false
    }

    /// playerViewController restore Interface For PIP
    func playerViewController(playerViewController: AVPlayerViewController, restoreUserInterfaceForPictureInPictureStopWithCompletionHandler completionHandler: (Bool) -> Void) {

    // if topView and navigation controller :
        if let topViewController = navigationController?.topViewController {
            topViewController.presentViewController(playerViewController, animated: true) {
                print("ready detailvc restore presentViewController")
                completionHandler(true)
            }
        }
        else {
            completionHandler(false)
        }
    }
}
