Difficulties converting to Swift 3
<p>After converting from Swift 2 to Swift 3 (even after converting edit-> convert -> to current swift syntax) I am getting lots of errors.   Especially: </p>

<p><a href="https://i.stack.imgur.com/f3D9L.png" rel="noreferrer"><img src="https://i.stack.imgur.com/f3D9L.png" alt="this"></a></p>

<p>I am shown total 90 errors for my project which was working fine in Swift 2 before i downloaded this beta Xcode 8.0 and converted to Swift 3</p>

<p>Is this a conversion mistake I am making?</p>
