And Swift's Codable protocol was designed to provide a powerful and useful mechanism to convert JSON data into Swift structs. Well, JSON is arguably the most common data format that we use to exchange data on the web. In this post, I want to take a look at Swift's Codable protocol. But that's way beyond what I want to cover in this post. Objects in Javascript are very comparable to dictionaries in Swift, except they aren't strongly typed and they have a couple of extra features. Javascript doesn't have strong typing, so a JSON object in Javascript is really just a JavaScript Object. There are two different fashions for merging: merge modifies the original JSON, whereas merged works non-destructively on a copy.When you're working with Javascript, this JSON data can be easily decoded into a Javascript object. In a case where two fields in a JSON have different types, the value will get always overwritten. In case of both values being a both JSON-values are getting merged the same way the encapsulating JSON is merged.In case of both values being a the values form the array found in the other JSON getting appended to the original JSON's array value.If both JSONs contain a value for the same key, mostly this value gets overwritten in the original JSON, but there are two cases where it provides some special treatment: Merging a JSON into another JSON adds all non existing values to the original JSON which are only present in the other JSON. It is possible to merge one JSON into another JSON. object, // use user.object instead of just user "apikey " : "supersecretapitoken " With other JSON objects let user: JSON =
