Dec 30, 2020 · Question or problem in the Swift programming language: It’s now easier with Swift 4 to encode / decode to and from JSON or Properties list. But I can’t find how to encode to Data using Codable, without using Objective-C methods initWithCoder and encodeWithCoder. Considering this simple class: struct Question: Codable { var title: String var […] Codable provides the best way to map those JSON payloads to your Swift models. Thanks to automatic code synthesis from the compiler, tasks that used to take hours of engineering and hundreds of lines of boilerplate can now be done in a few moments — often with little to no additional code.
The Codable protocol is Apple's contribution to a standardised approach to encoding and decoding data. If you've been a Swift developer for a while, you might recall that, before Apple introduced Codable in Swift 4, you had to perform data mapping from and to external representations either manually or by importing third-party libraries.Swift and iOS software engineering blog, Swift compiled is maintained by Alex Brown releases weekly articles and tutorials on iOS and Swift programming.
