Swift 3.0:

func showPickerInActionSheet() {

    let title = ""
    let message = "\n\n\n\n\n\n\n\n\n\n";
    let alert = UIAlertController(title: title, message: message, preferredStyle: UIAlertControllerStyle.actionSheet);
    alert.isModalInPopover = true;


    //Create a frame (placeholder/wrapper) for the picker and then create the picker
    let pickerFrame = CGRect(x: 17, y: 52, width: 270, height: 100)
    let picker: UIPickerView = UIPickerView(frame: pickerFrame)


    //set the pickers datasource and delegate
    picker.delegate   = self
    picker.dataSource = self

    //Add the picker to the alert controller
    alert.view.addSubview(picker)

    //Create the toolbar view - the view witch will hold our 2 buttons
    let toolFrame = CGRect(x: 17, y: 5, width: 270, height: 45)
    let toolView: UIView = UIView(frame: toolFrame)


    //add buttons to the view
    let buttonCancelFrame = CGRect(x: 0, y: 7, width: 100, height: 30) //size & position of the button as placed on the toolView

    //Create the cancel button & set its title
    let buttonCancel: UIButton = UIButton(frame: buttonCancelFrame);
    buttonCancel.setTitle("Cancel", for: .normal)
    buttonCancel.setTitleColor(UIColor.blue, for: .normal)
    toolView.addSubview(buttonCancel); //add it to the toolView

    //Add the target - target, function to call, the event witch will trigger the function call
    buttonCancel.addTarget(self, action: Selector("cancelSelection:"), for: UIControlEvents.touchDown);


    //add buttons to the view

    let buttonOkFrame = CGRect(x: 170, y: 7, width: 100, height: 30)//size & position of the button as placed on the toolView

    //Create the Select button & set the title
    let buttonOk: UIButton = UIButton(frame: buttonOkFrame);
    buttonOk.setTitle("Select", for: UIControlState.normal);
    buttonOk.setTitleColor(UIColor.blue, for: UIControlState.normal);
    toolView.addSubview(buttonOk); //add to the subview

    buttonOk.addTarget(self, action: #selector(HomeViewController.saveDelayTime), for: UIControlEvents.touchDown);

    //add the toolbar to the alert controller
    alert.view.addSubview(toolView);

    self.present(alert, animated: true, completion: nil);
}

func saveProfile(sender: UIButton){
    // Your code when select button is tapped

}

func saveUser(sender: UIButton){
    // Your code when select button is tapped
}

func cancelSelection(sender: UIButton){
    self.dismiss(animated: true, completion: nil)

    // We dismiss the alert. Here you can add your additional code to execute when cancel is pressed
}

// returns number of rows in each component..
func numberOfComponents(in pickerView: UIPickerView) -> Int{
    return 1
}

func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
    return 60
}

// Return the title of each row in your picker ... In my case that will be the profile name or the username string
func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
    return "\(row)"

}

func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
    selectedTime = row
}

func saveDelayTime() {
    self.dismiss(animated: true, completion: nil)
    UserDefaults.standard.set(selectedTime, forKey: "DelayTimeKey")
    let _ = UserDefaults.standard.synchronize()
}
