Tjeerd in 't Veen talks about how to use enums in Swift. He explains that they are actually optionals and that they themselves can also be optionals. He gives practical examples on how they can be leverages in real world scenarios and can even be used to replace inheritance or objects or protocols. This talk was recorded on July 18th, 2018 during the monthly CocoaHeadsNL meetup, this time at the office of Schiphol in ANWB in The Hague.
