Can't play video from documentsDirectory in iOS

Question

I'm trying to play a video downloaded to the device's document directory. For some reason, it won't happen. All I get is this symbol:

Here's my code:

let documentPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0] as String
let videoFileUrl = URL(fileUrlWithPath: documentPath)
let videoFilePath = videoFileUrl.appendingPathComponent("somVideo.mp4").path
if FileManager.default.fileExists(atPath: videFilePath){
    let player = AVPlayer(url: URL(string: videoFilePath)!)
    let playerViewController = AVPlayerViewController()
    playerViewController.player = player
    self.present(playerViewController, animated: true) {
        playerViewController.player!.play()
    }
}
else {
    print("File doesn't exist")
}

The file exists at the location - I have checked my documents directory for the simulator - and the else statement isn't fired. Nothing else is printed to the console.

Any help would be appreciated.

Here's the answer the OP edited into the question (and which was subsequently rolled back because answers should be answers). If OP posts a separate answer, I'll remove this one.

I managed to get it working with a little help from a colleague of mine. Here's the answer if anyone should be interested:

let urls = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
if let docDir : URL = urls.first {
    let videoUrl = docDir.appendingPathComponent("\(objectId).mp4")
    do {
        let videoExists : Bool = try videoUrl.checkResourceIsReachable()
        if videoExists {
            let player = AVPlayer(url: videoUrl)
            let playerController = AVPlayerViewController()
            playerController.player = player
            self.present(playerController, animated: true) {
                playerController.player!.play()
            }
        }
        else {
            print("Video doesn't exist")
        }
    }
    catch let error as NSError {
        print(error)
    }
}
