我来了，swift

简介

通过access modifier控制代码的访问权限，用来隐藏一些不必要的实现细节

*Controls*	*Description*
public	declarations are accessible from everywhere
private	declarations are accessible only within the defined class or struct
fileprivate	declarations are accessible only within the current swift file
internal	declarations are accessible only within the defined module (default)

适用于各个类型（class/struct/enum/func/property/initializers/subscripts）
