What is a good example to differentiate between fileprivate and private in Swift3

Question

This article has been helpful in understanding the new access specifiers in Swift 3. It also gives some examples of different usages of fileprivate

Answer 1

filePrivate - access controll level is within the file.

case 1: If we create extension with in same class file and try to access fileprivate function or fileprivate property in its extension - access allowed
case 2: If we create a extension of class in new file - And now try to access fileprivate function or fileprivate property - access not allowed

private - access control level is with in lexical scope

case 1: If property or function is declared as private in class - then scope is by default the class. case 2: if private instance is declared with in function body - then scope of instance is limited to function body.
