RESTful API Experience: Data Management With Alamofire In iOS Project

Alamofire

Hello everyone. We will see Alamofire data management in this article. Let’s begin now.

What is Alamofire?

Alamofire is a Swift-based HTTP networking library for iOS and macOS. It provides an elegant interface on top of Apple’s Foundation networking stack that simplifies a number of common networking tasks.

How to manage Alamofire data?

In this article, you’ll perform basic networking tasks including:

• Requesting data from a third-party RESTful API.
• Sending request parameters.
• Converting the response into JSON.
• Converting the response into a Swift data model via the Codable protocol.

First, let’s create a RESTful API for ourselves. You can use https://www.mockable.io/ site for this. In the following steps, you will see an example of creating an api on this site.

How to create a RESTful API?

Step 1: Click on the “Try Now!” button.

• (You must register on this site.)

Step 2: Click on the “DEFINE A NEW REST MOCK” button.

Nice! We have a Rest Mock.

Let’s customize data and start the service.

Copy this link.

It seems perfect. Let’s create a new project or open your existing project.

We have to install the pod in the project directory. (You can run these commands in terminal.)

cd /Users/yourname/Desktop/testAlamofire
pod init
pod install

We have a podfile. Let’s open this file, add necessary codes and run ‘pod install’ code from terminal.

pod "Alamofire" // add in podfile
pod install // run in terminal

It seems perfect. Now, define your objects to the class. (and import Alamofire)

We need to create a model for our Alamofire data. Let’s do it.

Step 1: Create a new Swift file in Project Navigator. Let’s enter a name for this file.

Step 2: Let’s customize this class for our Alamofire data.

• Decodable: A type that can decode itself from an external representation.
• CodingKey: A type that can be used as a key for encoding and decoding.

Let’s add a DataRequest variable to pull data from the link.

Now let’s create a function for request.

Call this function from the fetchDataButtonClicked function. Thus, your data will be updated.

Now try it.

Thank you for reading.
