How to find index Path for a selected Collection View Cell?

How to find index Path for a selected Collection View Cell without using didSelectItemAtIndexPath and prepareForSegue?

I am using this indexPath within AlertViewController. I dont know how to get this indexPath in AlertView Controller.

//Edit Selected Category
        let alertController = UIAlertController(title: "Alert", message: "Rename your ", preferredStyle: .alert)
        let actionOK = UIAlertAction(title: "OK", style: .default)

        alertController.addTextField(configurationHandler: {(textField: UITextField) -> Void in

            if let iP: IndexPath = self.collCategory.indexPath(for: CategoryCollectionCell) {

                print("IP \(iP)")
            }

        })

        alertController.addAction(actionOK)
        self.present(alertController, animated: true, completion: nil)

Here's my solution

private func getCurrentIndex() -> Int {
    return Int(collectionView.contentOffset.x / collectionView.frame.width)
}

Swift 4-4.2 - Returns index of cell.

override func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
    let cellIndex = indexPath[1] // try without [1] returns a list.
    print(indexPath[1])
    chapterIndexDelegate.didTapChapterSelection(chapterIndex: test)
}

Use this:

    func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
        collectionView.selectItem(at: indexPath, animated: false, scrollPosition: .bottom)
}

Then u will get path from collectionView.indexPathsForSelectedItems

if let collectionView = self.YourCollectionView,
    let indexPath = collectionView.indexPathsForSelectedItems?.first,
    let cell = collectionView.cellForItem(at: indexPath) as? YourCell {
}

To select cell without didSelect method then you can use Tap Gesture to detect cell. Check below method to add gesture to cell and detect gesture.

//Add below code to collectionview cell return method

if let gestures = cell. contentView.gestureRecognizers {
            gestures.forEach({ (tap) in
                if tap .isKind(of: UITapGestureRecognizer.self) == true {
                    cell.contentView.removeGestureRecognizer(tap)
                }
            })
        }
let tapRec = UITapGestureRecognizer.init(target: self, action: #selector(didTap(sender:)))
cell.contentView.isUserInteractionEnabled = true
cell.contentView.addGestureRecognizer(tapRec)

//Create method to detect gesture recognizer

func didTap(sender: UIGestureRecognizer)
{
    let cell = sender.view?.superview as! yourCell
}

Hope it will work.

Inside your CollectionView delegate call 

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath) 
    print(" Row : \(indexPath.row)")

    return cell
}
