An extension to decode nested model of any depth with a keyPath.
It means you can do these:
let decoder = JSONDecoder()
let post1 = try decoder.decode(Post.self, from: data, keyPath: "post")
let post2 = try decoder.decode(Post.self, from: data, keyPath: "nested.post")
let post3 = try decoder.decode(Post.self, from: data, keyPath: "nested.post.embedded_post")with this JSON data:
{
"post": {
"title": "Hello",
"detail": "My post, hello!",
"likes": 20
},
"nested": {
"post": {
"title": "What is this",
"detail": "The nest seems to work",
"likes": 14,
"embedded_post": {
"title": "Embedded Post",
"detail": "Embedded post also work",
"likes": 100
}
}
}
}and the Post model:
struct Post: Decodable {
let title: String
let detail: String
let likes: Int
}Just drag NestedDecodable.swift to your project.
