Download JSON data from an online location into your iOS apps. You’ll work a sample list of contacts with email addresses, phone numbers, names, and other relevant information. You’ll then see how to format the data properly and list it in a TableView to be more user-friendly to read for display in your app.
Working with JSON in iOS is one of the most useful pieces of knowledge for a developer. It’s used on a daily basis in a wide variety of apps. Displaying online data in an app is an essential part of the iOS ecosystem. Learn how to download text from a server and then format the data properly with Codable in Swift. Using custom cells, you’ll build a TableView then place everything in an adaptable AutoLayout. Finally, you’ll populate the TableView with the formatted JSON data represented by an array of custom items. By the end of this video, you’ll be able to incorporate JSON data into your apps in a user-friendly and easily accessible manner.
What You Will Learn
Format JSON data properly with Codable in Swift
Build a TableView with custom cells
Place data in adaptable AutoLayout
Who This Video Is For
iOS developers with advanced skills in Xcode and Swift who want to incorporate JSON data displayed properly in their apps.
Get working with JSON in Xcode in this video that shows you how to download JSON data from an online location into your iOS apps.

Hello, I’m going to show you how to create simple contacts app for iOS. That will list a few contacts with names, phones, and other information for random people. At the start of the project, I will show you how to create the basic iOS project and setting up the files needed to format the downloaded JSON data properly. Here we will use decodable framework from Apress standard libraries.
Then we will download the JSON data from the server. To test that with properly formatted JSON files, we will bring the downloaded result in the debug area of the project as a text. Later in the app, we will remove this part, and we will display all the data in the TableView.
After successfully downloading the data, we will use AutoLayout in the storyboards to add our TableView to the screen. Then we will add the TableView cell in the TableView itself so it can design it for our contacts. I will show you how to connect the design of the cell in the table with their Swift files.
Here will create default TableView methods and prepare our TableView cell for the adjacent data. We should properly connect all JSON elements with their elements in the TableView cell. Here we can finally remove the all debug printing of the JSON data and display it in the proper format in our TableView. Finally, I will show you how to add additional entries in your JSON file and display them in the app itself.
