你要创建一个UIimageview的控件imageView（控件名称），然后用imageView.image= newImage需要把UIimageview的控件加载到视图上

let imageView = UIImageView(frame: CGRect(x: 20, y: 100, width: 100, height: 100))

        let imageUrl = NSURL.init(string: "http://course.gdou.com/gxk/html/hw/1.jpg")
        let myData = NSData.init(contentsOf: imageUrl! as URL)
        let myImae = UIImage.init(data: myData! as Data)
        imageView.image = myImae
        self.view.addSubview(imageView)
