keyboard does not dismiss after async task in swift

Question

I’m doing a searching task using UItextField and I tap search button it should begin async task fo calling web api and also dismiss the keyboard. But keyboard remains there. Here is the code

func textFieldShouldReturn(_ textField: UITextField) -> Bool {

   attemptPost { (success) in
       DispatchQueue.main.async {
        spinner.stopAnimation(self)
        btnOk.isEnabled = true
        btnCancel.isEnabled = true
    }

     // after this keyboard should dismiss but does not do so
      return true
}

func attemptPost(_ completion:@escaping (Bool)->()) {
    // some code
}

I want keyboard to dismiss once we tap search button and async task should also start.

You must resign the first responder.

func textFieldShouldReturn(_ textField: UITextField) -> Bool {

   attemptPost { (success) in
       DispatchQueue.main.async {
        spinner.stopAnimation(self)
        btnOk.isEnabled = true
        btnCancel.isEnabled = true
    }

   textField.resignFirstResponder()
      return true
}
