Swift 4.0 brought many great new features, including multi-line strings, better keypaths, and lots of improved dictionary functionality. But it also gave us Codable for the first time: by far the easiest, safest way to convert Swift objects into JSON and XML.
However, Codable had one particular annoyance that hit most users: if your JSON used snake_case for its key names and your Swift code used camelCase for its property names, Codable wouldn’t be able to convert between the two – you needed to create your own CodingKeys mapping to explain how the two matched up.
Apple’s newest API, ARKit, makes the exciting world of Augmented Reality available to every iOS developer, but where do you get started? Come with us on an Augmented Reality journey to build an AR solar system and learn how to make your first ARKit application.
