URLSession: JSON GET & POST Requests | Swift 3, Xcode 8

Kilo Loco explains how to make GET and POST network requests using URLSession and handle JSON data in Swift.

Today we go over URLSession and how to make JSON GET and POST requests. This is a step by step tutorial that will explain what is happening in each line of code so you can grasp the full concept of how URLSession works and how to explore different APIs. Networking is a major part of iOS development and is almost always required for iOS developer jobs. The more you understand how to create your own networking requests, as opposed to using third party frameworks like Alamofire, the more efficient and lightweight your code can be. By the end of this tutorial, you will know how to send a GET and POST request with a JSON body, know how to convert data bytes into legible JSON, and become aware of some common bugs that show up when using URLSession. The finished project will be posted up on github which you can find the link here: github.com/Kilo-Loco/URLSessionJSONRequests If you have any questions or comments about the tutorial, or want to suggest a video to make, feel free to leave a comment below, or reach out to me on Twitter: twitter.com/kilo_loco If you found this tutorial helpful, make sure to subscribe to the channel for more great tutorials.
