JSON

This library helps you dealing with NSJSONSerialization. It has simple methods to convert NSData into a JSON object and to get a JSON object from a file.

JSON Object from NSData

If converting the NSData to JSON fails, you'll get a ParsingError.Failed error.

guard let url = URL(string: "http://httpbin.org/get") else { return }
let request = URLRequest(url: url)
URLSession.shared.dataTask(with: request) { data, _, error in
    do {
        let json = try data?.toJSON() as? [String : Any]
        print(json)
    } catch {
        // Handle error
    }

    expectation.fulfill()
}.resume()

  }, 
  "origin": "000.00.000.000", 
  "url": "http://httpbin.org/get"
}
*/

JSON Object from file

If parsing the JSON fails, you'll get a ParsingError.Failed error. If the file is not found you'll get a ParsingError.NotFound error.

For files in the main bundle:

import JSON

var users: Any?
do {
    users = try JSON.from("users.json")
} catch {
    // Handle error
}

For files in in other bundles (for example Tests file bundle):

import JSON

var users: Any?
do {
    users = try JSON.from("users.json", bundle: Bundle(for: Tests.self))
} catch {
    // Handle error
}

Installation

JSON is available through CocoaPods. To install it, simply add the following line to your Podfile:
