title: What is a good example to differentiate between fileprivate and private in Swift3
body: <p>This <a href="https://lists.swift.org/pipermail/swift-evolution/Week-of-Mon-20160328/013664.html" rel="noreferrer">article</a> has been helpful in understanding the new access specifiers in <code>Swift 3</code>.  It also gives some examples of different usages of <code>fileprivate</code> and <code>private</code>. </p>
  
  <p>My question is - isn't using <code>fileprivate</code> on a function that is going to be used only in this file the same as using <code>private</code>?</p>
