⚠️ Experimental Stuff ⚠️

With SwiftUI & the new UICollectionView layout APIs being all the rage within the iOS community, I didn't know which to pick first. So I went ahead and implemented both in the same app.

This is an experimental project to see how some of the newly announced iOS 13 features works. A big part of the project is made up of UICollectionView Compositional Layout and SwiftUI elements. There is also a dash of Combine framework. I decided to mix and match UIKit & SwiftUI components to see how apps could integrate.

Used UICollectionViewCompositionalLayout to create 3 layouts without nesting UICollectionViews and all working on the same data type, it's truly is amazing.

I created three different cells, which are SwiftUI components hosted onto UIKit using UIHostingController, which basically takes a SwiftUI View and produces a UIViewController. I've used autolayout as the glue, and used Combine framework to pass data between these two worlds.

Each of the horizontal rows are unique layouts.

Nothing! This was a weekend experiment to see what the new iOS13 APIs had to offer.

• Paul Hudson's SwiftUI By Example
• WWDC [215: Advances in Collection View Layout] (https://developer.apple.com/videos/play/wwdc19/215/) & 220: Advances in UI Data Sources
• Inspired by [Brian Voong's course] (https://www.letsbuildthatapp.com/course/AppStore-JSON-APIs) where he built the app store using the old APIs and got me thinking.
