Thanks for this video! I had been searching how to parse JSON successfully from a GET request for a while.

Great tutorial, very helpful! I appreciate how you focused on the topic and did not ramble off on tangential issues (as many tutorials do).

Hi Brian, Do you have the source code for this project? I cant seem to figure out what I'm getting wrong

You can use Postman to make requests with any type of parameters and get cool printed JSON in response. Also use QuickType to convert JSON text to swift codable model

Can you please make a video where you can show us how to do API calls like get post delete upload in iOS.
Love your channel

Hey Brian, thx a lot! Adapted the request method it into my own project and it worked right away :)

[elenekotu]

Bad idea to show your app key with all these trolls on internet 😂 nice video!

[linusb]

This is a great tutorial! I am struggling to understand the escaping completion handler of the request function. Can you offer any feedback to explain the high level logic of that code?

[JohnKitching]

Great work Brian. Can you talk us through the steps to get to your starting point please? I've tried a few ways but never get a tableviewcontroller in the swift file. I'm using Xcode 11

Thank you very much for a great video! So useful and easy to understand! Could you please explain why you did not use [weak self] when updating tableView in didSet?
