These are notes I’ve taken while watching the video of the corresponding session. They don’t have all the information contained in the video, but I’ve tried to still write the main points for my personal use cases.

This is the second time I’ve installed the first beta on my Mac. I usually wait until beta 5 at least since it is usually way too unstable. The other time I did that was when they unveiled Swift.

SwiftUI and Combine are the future of iOS development. I’ve used a similar paradigm with Flutter for a while and it is a great way to both build UI interfaces and reason about data.

The key takeaway is: UI as a function of state. The UI is immutable and it gets redrawn based on the state. There is a single source of truth for the data.
