How to deal with root level Array? about argo

[tonyd256]

If each one of those objects in the array has a model that conforms to JSONDecodable then it's not hard. You can use mapDecode after you get the JSONValue back from JSONValue.parse

[tonyd256]

That is if you're using Argo 3.x or 4.x ... If you are on master then it will be different.

@tonyd256 How would you do that today? JSONValue isn't available anymore it seems.

Noted this in #17 but I'll drop it in here as well:

JSONValue was renamed JSON at some point (possibly pre-1.0?). The way you'd want to decode an array of objects now is to use the decodeArray helper function:

import Curry // Curry.framework: https://github.com/thoughtbot/Curry
import Argo

struct Foo {
  let id: Int
  let foo: String
}

extension Foo: Decodable {
  static func decode(json: JSON) -> Decoded<Foo> {
    return curry(Foo.init)
      <^> json <| "id"
      <*> json <| "foo"
  }
}

let foos: [Foo]? = decodeArray(json).value
