You are calling the function with a string parameter, but the function does not take the string parameter. Either the call should be

您正在使用字符串参数调用函数，但该函数不接受字符串参数。要么调用应该是

presentWinningAlert()

without passing any arguments or the function should be modified to

不传递任何参数或函数应修改为

func presentWinningAlert(title: String){
moveCounter = 0
let alert = UIAlertController(title: title, message: "byr", preferredStyle: UIAlertControllerStyle.Alert)
