Sushi is a lightweight HTTP networking library with JSON decoding built in - written in Swift.

Installation

Cocoapods

In your your Podfile file add the following...

pod 'Sushi' '~> 1.2.0'

Carthage

Support for carthage will be added in a future release

Guide/Documentation

Sushi was designed around one particular objective - JSON decoding.

Step 1: Modeling your data

In this example, UserModel is the data model we expect to receive after creating and sending a request. All models should conform to the Codable protocol.

struct UserModel: Codable {
    let userId: Int
    let id: Int
    let title: String
    let completed: Bool
}

Step 2: Create an Endpoint

An Endpoint is a representation of a network endpoint that contains information such as:

Model - Data type represented from a request response. httpMethod - HTTP Method: GET, POST (others coming soon) url - A String with information to open a request

import Sushi

struct UserEndpoint: Endpoint {
    typealias Model = UserModel

    var httpMethod: HTTPMethod = .GET
    var urlRequest: String = "https://jsonplaceholder.typicode.com/todos/1"
}

Step 3: Calling a request

Finally, we create an instance of Sushi and UserEndpoint. Then create the request with the information provided from endpoint.

Sushi handles the request asynchronously, once the request has been completed either the success or failure callbacks will be called.

import Sushi

var endpoint = UserEndpoint()
var sushi: Sushi = Sushi()

sushi.request(endpoint: endpoint, success: { (data) in
    print("\(data)") // Data conforms to UserModel and Swift can now confidently infer properties from it
    
    print("\(data.userId))      // userId: 0
    print("\(data.id))          // id: 1234
    print("\(data.title))       // title: "Title received"
    print("\(data.completed))   // completed: false
})
