    The only thing u need is to create a Timer

      func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
        let text = searchText.trimmingCharacters(in: .whitespacesAndNewlines)
    
    // Create a Timer in this or parent class.
        debounceTimer.invalidate() // just in case this button is tapped multiple times
    
    
        // start the timer
        debounceTimer = Timer.scheduledTimer(timeInterval: 0.8, target: self, selector: #selector(self.startSearch(_:)), userInfo: text, repeats: false)
    }
    
    func startSearch(_ timer: Timer) {
        if let searchText = timer.userInfo as? String {
            print("Searching: \(searchText)")
    
            // make your service call here ...
        }
    }
