Then access control (b) write, action:
------------------------------------------ ------ initializer --------------------------------------------------
1. If no parameter like a public class initialization in another module to invoke the compiler generated default, must provide a public display, no arguments initializer
Because the default initializer public class is internal level
2. The structure has private \ fileprivate storage instance property, then his "member initializer" is also a private \ fileprivate level
Otherwise the default is internal
3.required saying their class initialization must have the same level of access? ? ? ? ? (To be supplemented)
---------------------------------------- access enumeration, protocol settings - -------------------------------------------
1. Enumeration
// not set the access level for each individual case, each case automatically receive the access level enum
The first // Here is wrong
2. Protocol
The protocol defined in claim individual access level can not be set to automatically receive access level outside, the same enumeration
