Word传感器在Xcode编辑器中不起作用

Question

当我强行写“Any UI”时，我面临编译错误。

这是我的代码：

import UIKit

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        var mybutton  =  UILabel()
        // Do any additional setup after loading the view, typically from a nib.
    }

}
