    Fix iOS Project Swift Errors
In order to build the iOS app in the latest XCode, you need to convert the project to Swift 3.0. After you do this, when you try to run or archive the project, you will get a bunch of errors. This section explains how to fix them.
IMPORTANT NOTE: Fix all the RED errors. There will also be yellow triangles and the option to "update to recommended settings". Do NOT fix these things and do NOT update to recommended settings.
Info from Apple on what has changed in Swift: http://adcdownload.apple.com/Developer_Tools/Xcode_8_beta_6/Release_Notes_for_Xcode_8_beta_6.pdf ("New in Xcode 8 beta 6 - Swift Compiler" section on page 8)
"NSURL" is not implicitly convertible to "URL"
