How to delete files from Firebase Storage and Table View

I'm creating a Customer Management app for iOS. I'm using Firebase Firestore and Storage. There is a part of my app when the user can attach document to each customer. I upload and then download the file in local folder to be able to display the file name in a TableView and open with QLPreviewController.

I save the path and name of uploaded file in Firestore.

This is my code where I want to delete the file with swipe. This work only if i try to delete the first file in table view but if try to delete the third file for example it will delete the first.

I have try this but it doesn't work for me:
