title: Absolute value function abs() unavailable in Swift 3.0. Use abs(_:) free function?
body: <p>I am converting a Swift iOS project to Swift 3.0 using Xcode 8 Beta 4. The absolute value function shows to be unavailable. Here is a code sample...  </p>
  
  <pre><code>let myInt = -3
  let myAbsoluteInt = abs(myInt)
  </code></pre>
  
  <p>The second line results in an error stating: <code>'abs' is unavailable: Please use the 'abs(_:)' free function</code>.</p>
  
  <p>Ideas?</p>
