My addSubview for an image adds a larger view than expected - swift

Question

I have an image inside a table view cell where the user can user tap on the image the app adds a subview with that image in it. The table view can be longer than the screen. The issue is that if I have the table view scrolled up a bit and the user taps on the image, the image in the subview is scrolled up. My guess is that calling newImageView.frame = UIScreen.main.bounds isn't what I need?
#IBAction func imageTapped(_ sender: UITapGestureRecognizer) {
let imageView = sender.view as! UIImageView
let bookImage = UIImageView(image: imageView.image)
bookImage.frame = UIScreen.main.bounds
bookImage.backgroundColor = .black
bookImage.contentMode = .scaleAspectFit
bookImage.isUserInteractionEnabled = true
let bookImageTap = UITapGestureRecognizer(target: self, action: #selector(dismissFullscreenImage))
bookImage.addGestureRecognizer(bookImageTap)
self.view.addSubview(bookImage)
self.navigationController?.isNavigationBarHidden = true
self.tabBarController?.tabBar.isHidden = true
}
this is what it’s suppose to look like wherever I tap it
this is what happens if I scroll the table view up and tap the image

Answer 1

self.view is a table view, which is a kind of scroll view. If you add a subview to that, it will scroll with the table view. I suppose you don't want that.
Therefore, you should not add the bookImage as a subview of self.view. You can instead add it as a subview of the window:
let window = (UIApplication.shared.delegate as! AppDelegate).window
window?.addSubview(bookImage)
