＃＃ 你好，世界

只有我们必须将方法print("Hello World") （从库UIKit）添加到类ViewController的函数viewDidLoad()中：

```斯威夫特 导入UIKit

class ViewController：UIViewController {

override func viewDidLoad() { 
    super.viewDidLoad() 
    // Do any additional setup after loading the view, typically from a nib. 
 
    print("Hello World") 
 
 } 

} ```

##输出： ```

你好，世界 ```
