iOS Swift - Lists and Data Display

Given this code snippet inside a UITableViewDelegate method, what happens when the user swipes the cell?

let deleteAction = UIContextualAction(style: .destructive, title: "Delete") { _, _, completionHandler in
    print("Deleted")
    completionHandler(true)
}
let configuration = UISwipeActionsConfiguration(actions: [deleteAction])
return configuration

AA red "Delete" button appears; tapping it prints "Deleted" and closes swipe

BThe cell immediately deletes without user interaction

CNothing happens because completionHandler is not called

DThe swipe gesture is disabled

Step-by-Step Solution

Solution:

Step 1: Analyze swipe action setup
A destructive style button labeled "Delete" is created with a handler that prints and calls completionHandler(true).
Step 2: Understand user interaction
Swiping reveals the button; tapping it triggers the handler, printing "Deleted" and ending the swipe.
Final Answer:
A red "Delete" button appears; tapping it prints "Deleted" and closes swipe -> Option A
Quick Check:
Swipe button tap triggers handler = A red "Delete" button appears; tapping it prints "Deleted" and closes swipe [OK]

Quick Trick: Completion handler true ends swipe and triggers action [OK]

Common Mistakes:

Thinking swipe deletes immediately without tap
Forgetting to call completionHandler(true)
Assuming swipe gesture disables without code
