SwiftUI Components & Extension that saves iOSDev time.
### UIKit is **EVENT-Driven** framework - We could reference each view in the hierarchy, update its appearance when the view is loaded or as a reaction on an event.
### SwiftUI is **Declarative, State Driven** framework - We cannot reference any view in the hierarchy, neither can we directly mutate a view as a reaction to an event. 
Instead, we mutate the state bound to the view. Delegates, target-actions, responder chain, KVO .. replaced with Closures & bindings.

iOS Code Review Checklist

Avoid Type Inference
Prefer using Higher Order Functions
Write DRY code (Don’t Repeat Yourself)
Make sure that there are no force unwraps
Make sure that there are no retain cycles
Check if any deprecated API is being used
Check if any hardcoded checks (generally strings) can be changed to enum.
Prefer enum, switch over if else.

Colorslide tutorial

Welcome to the Colorslide game tutorial. It will take you through the process of adding a simple GUI flow to an existing multi level mobile game. It is assumed that you know your way around the editor. If you don't, please check out our manuals and beginner tutorials.

The starting point for this tutorial is this project. It contains everything you need:

A simple but fully playable game where the player slides colored bricks on a tiled board until every brick's color matches the tile they sit on.
4 example levels are included. They are of various difficulty. Each level is built in its own collection.
Assets are included so you can build any number of levels, using the built in tile editor.
After having finished the tutorial, you will have accomplished the following:
