SwiftUI is a powerful UI framework introduced by Apple that allows developers to build user interfaces across all Apple platforms using a declarative syntax. It is designed to be a multiplier on your efforts, meaning once you have a user interface built using SwiftUI for one platform, you have an excellent start for building native apps on others. SwiftUI's capabilities extend beyond views to the entire app definition, which is built on the same principles that views follow. An app is a declarative structure defined by scenes, and SwiftUI enables you to compose scenes together, especially on multi-windowed platforms like macOS.
SwiftUI views are value types defined using structs, which are descriptions of what the current state of the UI should be. This declarative approach allows SwiftUI to automatically keep your UI up to date as your view state changes over time, eliminating boilerplate and update bugs. SwiftUI also supports interoperability with other frameworks, allowing you to use UIKit and AppKit views within your SwiftUI view hierarchy.
For more detailed information on SwiftUI, you can refer to the session SwiftUI essentials (00:04:30) from WWDC 2024, which covers the fundamentals of views and how SwiftUI enables building apps across all platforms.
