AVPlayerViewController spielt kein Video?

Question

Ich entwickle eine App für iOS und ich habe Code erstellt, wo, sobald eine Zelle in einer Tabellenansicht ausgewählt ist, es zu einem AVPlayerViewController wechselt und einen lokalen Videoclip abspielt, abhängig davon, welche Zellenzeile ausgewählt wurde. Wenn es jedoch zum AVPlayerViewController wechselt, erscheint der Player, aber es wird kein Video abgespielt. Warum? Ich habe der didSelectAtRow-Funktion sogar eine Druckanweisung hinzugefügt, um sicherzustellen, dass die richtige Videodatei ausgewählt wird. Es sollte beachtet werden, dass der Code gut funktioniert, bis es Zeit ist, eine Videodatei abzuspielen (der Player erscheint, bleibt aber leer).

class DrillsViewController: UIViewController, UITableViewDelegate, UITableViewDataSource { 

var initialRow = Int() 
var arrayForKey2 = [[String]]() 
var keyIndex = Int() 
var headLabel = String() 
var labels = Array(trainingDict.keys) 
var playerViewController = AVPlayerViewController() 
var player = AVPlayer() 
var videoURL = [URL]() 
var videoUrl = [URL]() 
var drillVid = URL(fileURLWithPath: String()) 

var firstTips = ["Tip 1: Stay Hydrated", "Tip 1: Keep elbow tucked", "x", "Tip 1: Take quick breaks:", "Tip 1: Keep your head up", "Tip 1: Don't cross your feet", "Tip 1: Don't do more than 15 reps"]
