Iterating Videos - swift

Question

I am trying to get the player to iterate through an array of strings that reference the URL of videos. I can only get it to play one of the videos in the array, if I hardcode it in the code, but I cannot do it to iterate.
I have gotten to play one video while it is hard coded in but not iterate.
var playerArray = [AVQueuePlayer]()
var player = AVQueuePlayer()
// var URLSArray = [URL]()
var ItemArray = [AVPlayerItem]()
var videos = ["video1", "video2","video3"]
var playerController = AVPlayerViewController()
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
let videoNum = (self.videos.count-1)
// var URLSArray = [URL]()
// for n in 0...videoNum{
// let pathString = (Bundle.main.path(forResource: videos[n], ofType: "mov"))
// let StrToURL = NSURL(string: pathString!)
// URLSArray.append(StrToURL! as URL)
// }
var ItemArray = [AVPlayerItem]()
// var playerController = AVPlayerViewController()
for n in 0...videoNum{
let pathString = (Bundle.main.path(forResource: videos[n], ofType: "mov"))
//print(pathString!)
let StrToURL = URL(string: pathString!)
// print(StrToURL!)
// ItemArray = [AVPlayerItem(url: StrToURL!)]
ItemArray.append(AVPlayerItem(url:StrToURL!))
print(n)
print(ItemArray)
// let player = AVPlayer(playerItem: ItemArray[0])
player = AVQueuePlayer(items: [ItemArray[n]])
player.play()
}
// playerController.player = player
// present(playerController, animated: true) {
// player.play()
}
I want it to finish playing one video and move on to the next video in the array, how ever I hard code the video from the array it works but if I am trying to iterate it acts as if the URL isn't working. This is what it says 2019-06-14 13:08:44.718684-0400 Video[5439:1288491] NSURLConnection finished with error - code -1002

Declare only the player
var player = AVQueuePlayer()
In viewDidAppear map the string array to the URLs in the application bundle and then the URLs to the player items. Then create the queued player and start playing.
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
let videos = ["video1", "video2", "video3"]
let videoURLs = videos.compactMap{ Bundle.main.url(forResource: $0, withExtension: "mov")}
let itemArray = videoURLs.map{ AVPlayerItem(url: $0) }
player = AVQueuePlayer(items: itemArray)
player.play()
// playerController.player = player
// present(playerController, animated: true) {
// player.play()
// }
}
