Like this:

 
import UIKit
import AVKit
import AVFoundation

class ViewController: UIViewController {
    
    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        
        let destination = segue.destination as! AVPlayerViewController
        let url = Bundle.main.url(forResource: "myMovieName", withExtension: "m4v")
        
        if let movieURL = url {
            destination.player = AVPlayer(url: movieURL)
        }
    }
}

    let end = Date()
    let elapsedTime = end.timeIntervalSince(start)
    print("Elapsed Time: \(elapsedTime)")
}
