swift - How to get indexPath when image inside cell tapped

Question

I would like to implement feature that if profileImage tapped in tableviewCell, segue to detailView. I add tapGesture but I still can't figure out how to get indexPath to pass data. I tried like this but app will crash.

    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {

        if segue.identifier == "detailSegue" {
            let next: DetailViewController = segue.destination as! DetailViewController
          // pattern1
 let indexPath = tableView.indexPath(for: sender as! CustomTableViewCell)
         // pattern2
        let indexPath = tableView.indexPathForSelectedRow! as NSIndexPath

            next.data = datas[indexPath.row]
        }
    }

How can I fix this? Thank you in advance!

If you add UITapGestureRecognizer to an UIImageView then don't forget to set isUserInteractionEnabled property to true.

Create a variable to store selected indexPath.row

var selectedCell:Int!

In cellForRow method add gesture to the image view.

let tapGesture = UITapGestureRecognizer(target: self, action: #selector(self.tapBtnAction(_:)))
cell.imageView.tag = indexPath.row
cell.imageView.addGestureRecognizer(tapGesture)

In target method perform segue

func tapBtnAction(_ sender: UITapGestureRecognizer) {
    print("(sender.view.tag) Tapped")
    self.selectedCell = sender.view.tag
    self.performSegueWithIdentifier("detailSegue", sender: self)
}

In prepareforsegue method get data from the array.

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {

   if segue.identifier == "detailSegue" {
      let next: DetailViewController = segue.destination as! DetailViewController
       next.data = datas[self.selectedCell]
   }
}
