Keep Going with Apps: Build on the fundamentals you learned in Get Started with Apps. Learn to use SwiftUI to manage your app state and automatically update your app UI based on state changes; learn how to navigate between different views in an app and share data across those views; learn more about how to manage view layout using padding, spacers, and alignment.
