Segue to different controllers from one cell (a detail view and a avcontroller)

Question

When the cell is tapped if there is a video, I want to show only the video (in a avPlayerViewController), if there is no video it performs a segue to a detail vieww

I have tried this:

func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {


    let post = postArray[indexPath.item]
    let controller = PostDetailViewController.fromStoryboard(post: post)
    self.navigationController?.pushViewController(controller, animated: true)


    guard let videoURL = URL(string: post.videoLink)  else {
        return
            }

    let avPlayer = AVPlayer(url: videoURL)
    let avController = AVPlayerViewController()
    avController.player = avPlayer

    present(avController, animated: true) {
        avPlayer.play()
    }

}

It plays the video if there is one (from Firebase), but it also opens the detail view. So I wanted the cell to open only the video or only the detailview

Structure it so that, if there is no post.videoLink then it pushes the PostDetailViewController, otherwise it will play the video:

func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {

    guard let videoURL = URL(string: post.videoLink) else {
        //If there is no URL, then this else condition will be called. Otherwise, the code below the guard statement will be called, and the video player will appear.
        let post = postArray[indexPath.item]
        let controller = PostDetailViewController.fromStoryboard(post: post)
        self.navigationController?.pushViewController(controller, animated: true)
        return
    }

    let avPlayer = AVPlayer(url: videoURL)
    let avController = AVPlayerViewController()
    avController.player = avPlayer

    present(avController, animated: true) {
        avPlayer.play()
    }

}

I tried something like this `if post.videoLink == ""`, but it didn't work. How can I do that? – H. Osjir Oct 19 '19 at 15:05
Well, when a post doesn’t have a video associated with it, is `post.videoLink` equal to `””` or is it equal to `nil`? – David Chopin Oct 19 '19 at 15:29
When I make it equal to nil, i get `'nil' cannot be assigned to type 'String'`. I'm a bit new to swift, so I dont know what to do. – H. Osjir Oct 19 '19 at 15:45
Can you check what the value of `post.videoLink` is in a post without a video? I imagine it is equal to `””`. It cannot be equal to `nil`. – David Chopin Oct 19 '19 at 15:46
The videoLink is `””`when it is in a post without a video – H. Osjir Oct 19 '19 at 15:50

Thank you for your help, it worked when I put `pushViewController(controller, animated: true)` in `if post.videoLink == ""` – H. Osjir Oct 19 '19 at 16:07
