Given the following JSON and Codable conforming type, fill in the blanks such that decoding is successful without having to define a custom init(from: Decoder)
import UIKit
let json = """
{
"result": {
"title": "My First Blog Post",
"author": "Pasan Premaratne",
"date": "April 16, 2018"
}
}
""".data(using: .utf8)!
struct Post: Codable {
let title: String
let author: String
let date: String
}
let decoder = JSONDecoder()
let post = try decoder.decode([[String: Post]].self, from:json)

Example: decoder.decode([String: Post].self from:json). Notice no comma between parameters? It didn't work for me by adding the comma to separate parameters (which is right).
You'll need to do the same for the rest of the written test.

288 PointsYou have an extra set of bracket: let post = try decoder.decode([[String: Post]].self, from:json)
Should be: let post = try decoder.decode([String: Post].self, from:json), but this still give you a dictionary and not a type Post.
