📊 #SWIFTUI makes it easy to create beautiful UIs in no time, but it is just as easy to end up with a giant view that mixes view code and business logic.

🍏 Fortunately, Apple gave us some tools to keep the bloat in check and write maintainable and #reusable code.

🎬 In this #talk, I am going to show you how to:
refactor an existing SwiftUI view to make it more maintainable
turn it into a reusable SwiftUI component
add event handling
make the view configurable
add it to the Xcode component library
turn it into a shareable component that can be consumed via Swift Package Manager
and distribute it via GitHub and the Swift Package Index
