DynamicJSON is a dynamically typed JSON parser built upon the new @dynamicMemberLookup feature introduced by Chris Lattner in Swift 4.2. This allows us to access arbitrary object members which are resolved at runtime, allowing Swift to be as flexible as JavaScript when it comes to JSON.

Before

if let jsonObject = try? JSONSerialization.jsonObject(with: data, options: []) as? [String: Any],
   let user = jsonObject["user"] as? [String: Any],
   let username = user["username"] as? String {
	// ...
}

After

let username = JSON(data).user.username.string

Installation

• CocoaPods:

pod 'DynamicJSON', '~> 2.0.2'

(if you run into problems, pod repo update and try again)

• Carthage:

github "saoudrizwan/DynamicJSON"

• Or drag and drop DynamicJSON.swift into your project.

And import DynamicJSON in the files you'd like to use it.

Usage

1. Initialize
