Like I mentioned, JSON is a commonly used data format that is used for communication between, for example, clients and servers. Swift 2 has introduced a number of important additions that we'll be using in this tutorial, such as error handling and the guard statement. This tutorial requires that you are running at least Xcode 7, which includes version 2 of the Swift programming language.

In this tutorial, I'll be showing you how to work with the JSON data format in the Swift programming language on iOS, tvOS, watchOS, and OS X. Many modern APIs, RESTful web services in particular, support the JSON data format. Let task = session.The JSON data format is widely used across the modern web and it is one of the most common ways to transfer data. Let session = URLSession.init(configuration.

Create another swift file and add the below code.

Here we create a struct which act as model based on which we parse the JSON response.

Create a blank swift file and add the below code in it.

Open up Xcode and create a blank Xcode project.

Here in the response as you can see we get an array of JSON Objects from the server and each object has a text and author key along with their values. This command is known as client URL which can be used to do some networking stuff through terminal here in this case we perform a HTTP GET request and the web server returns a JSON response.

Open up the Mac terminal and run the following command.

We are going to build an iOS app which uses Quotes API ( type.fit/api/quotes) which returns around 1000 quotes from the web server in JSON format. It stores the data in key value pair similar to a Dictionary data structure. It uses human readable text to store and send data. JSON stands for JavaScript Object Notation.It is an open source data interchange format.

Hello everyone in this article we are going to see how to parse a JSON response from Web API in iOS app using Swift Codable Protocol.
