    Conversion Process from Objective-C syntax to Swift
The most important first step is to run Apple's "Convert to Modern Objective-C Syntax" refactoring, so that you're using array/dictionary literals and bracket-accesses; these will then be usable in Swift. Note also that I'm a beginner in Swift, so my apologies for any mistakes or incompleteness here.
