This is an iOS app designed to work with Led badge of my design. I wanted it to be remotely controlled (RGB led for the win). I started my work with some intro to SwiftUI, a new declarative toolkit for creating UI. Compared with UIKit it was much easier for me to create a custom UI like the led icon. Refreshing of the view is done automatically and designing the animations is a pleasure. MVVM pattern also worked with me better than MVC, it was easier to separate data from UI, and everything went together more logically. The app was splitted into two views - main one to control led individually and second one that leats you load the favourite colors to the badge with one click. What is still to do is a bluetooth handling.
