swift：谈谈swift几种常见属性的区别

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        //实例属性
        let p = Person()
      
        //存储属性
        print(p.age)

        //懒加载属性
        print(p.name)

        //类属性
        print(Person.height)

        //计算属性
        print(p.getAge)

        //全局属性
        print(commonProperty)
    }
}
//全局属性
var commonProperty = {()->String in
    print("Common Property1")
    return "Common Property"
    }()

class Person{
    //类属性
    static var height = {()->Int in
        print("Static Properties")
        return 170
    }()
    //存储属性
    var age = {()->Int in
        print("Store properties")
        return 26
    }()
    //计算属性
    var getAge:Int{
        get{
            print("Computed Properties")
            return age
        }
    }
  //懒加载属性
    lazy var name = {()->String in
        print("Lazy Properties")
        return "Lazy liyang"
    }()
    //构造方法
    init(){
        print("init")
    }
}
