Resources for my Swift×NW talk.
As app developers we have to deal with the challenges of stateful code every day. State machines are a powerful technique for managing state — but they’re underused in Mac and iOS development, in part because they can be awkward to implement in Objective-C. Swift changes that. Swift’s smart enums make implementing state machines quick, easy, and fun. In this talk we’ll look at how you can make your apps easier to write, debug, and evolve using state machines in Swift. Along the way, we’ll explore the power of enums, including associated values, methods, and properties.
