Swift 4: JSON With Encoder and Encodable
Rather than pore through all the source code for encoding and decoding, let’s take a different approach and step through a simple example: how does a single
Intinstance wind its way throughJSONEncoderand become JSON data?[…]
To summarize: our Swift values get turned into their Foundation object equivalents by
JSONEncoderand friends, then these objects get JSON-ified byJSONSerialization.[…]
Now what about the reverse, decoding? And how can you write custom encoders and decoders for formats other than JSON, say protocol buffers? Stay tuned for more, or why not dig into the code and see what you find?
