Error of where Type 'Timer' has no member 'scheduledTimer' in my code:

In the code below, I receive the error - Type 'Timer' has no member 'scheduledTimer' - which I thought was an import issue but seems to be constant despite the results. How can I remove this error from the following code?

import UIKit
import Foundation

class TimerInterfaceViewController: UIViewController {

override func viewDidLoad() {
        super.viewDidLoad()
        
        
        
        // scheduling a timer in repeat mode after each 2 seconds.
        let timer = Timer.scheduledTimer(timeInterval: 2,
                                         target: self,
                                         selector: #selector(handleTimerExecution),
                                         userInfo: nil,
                                         repeats: true) -> "Type 'Timer' has no member 'scheduledTimer'"
    }

    @objc private func handleTimerExecution() {
        print("timer executed...")
   

     }
}

}

The answer was ensuring that there is no other class called "Timer"!
