How and Why to Use Protocols and Delegates in Swift

In this short episode we take a closer look at why we used a protocol and delegate in part 3 of Building Instagram Stories from Scratch (which you can watch here: https://youtu.be/NbHYLNNQdhg )

This is one of the most important concepts in iOS programming, but it’s not that complicated once you see why and how to use protocols and delegates.

The code for this and all episodes can be found here on github: https://github.com/brightmediums/HowT... This project is in the folder titled "Why You Should Use a Delegate and Protocol".

Building Instagram Stories - Part 3 - And a Juggling Accident!

,

In this third part, we continue building Instagram Stories-like functionality from the ground up. Today, we are building a custom sticker picker as a modal view controller with a transparent, blurred background and a grid of emojis.

We will be using XCode 9, Swift 4 and iOS 11 for this tutorial. You will need to have XCode installed, so open App Store on your mac or hackintosh and start the download!

The code for this and all episodes can be found here on GitHub.

Start with the code for "Instagram Stories - Part 2 - Rotation and Resizing" if you want to follow along. Otherwise download the "After" code from "Part 3"
