How to make REST API calls & parse JSON with Swift 2.0

** NOTE: Code has changed dramatically from Swift 2.0 to 3.1. The video no longer matches the example code in GitHub, but the concepts are similar. **

Pulling a random stat out of thin air, I'd say 90% of web APIs are REST APIs. Don't quote me on the percent, like I said, I made it up. The point is, there's alot of data behind REST APIs and we need to know how to connect our iOS apps to get that data. In this tutorial, we're going to write Swift code to perform a GET and a POST request.

Really good man. Explained everything in broad strokes while other youtubers use 20 minutes :D Subscribed!

You sir have earned yourself a sub! I'm new to Swift, and by new I mean about 3 weeks new. I've been doing PHP development for years, and have been killing myself to make sense of accessing a REST API I've written. Your tutorial honestly just explained in 5 minutes what I've been trying to research and figure out for 72 hours. Great job!

Really nice tutorial! I prefer smaller steps in tutorials but this worked just fine :D There is not a lot of swift 2.0 material on the web at the moment so 2 thumbs up for that! :)

Hello all, it's always good to understand the core syntax and concepts before using libraries like Alamofire. I used libraries and encounter lots of issues when upgrading to Swift 2.3, 3. So now I'm using core codes like in this video. THanks!

It works like a charm! It helps me a lot. Thank you!

Great video! If the session is happening on another thread, why do I see a lot of other people using GCD? They usually do dispatch_async(queue, 0) { // some code }.

Why are they doing that if it's already on a secondary thread? Thank you!

Thanks for your wonderful explanation, I have a question how can we make a custom class for http communication using swift 2, And use methods of this custom class as and when required in an app by passing arguments to the methods.

[TheFhdude]

the idea of learning native languages like swift scares the shit out of me when I see the likes of codes at 2:10 and compare it with react native rest api fetch, :-)

[phillvaloyi]

I had a question, would your tutorial to post also work with UIImage and text from textfields to a mysql database if I made some tweaks to it?
