what is swift ui ?

SwiftUI is Apple's declarative user interface framework used to build apps across all of Apple's platforms. It is designed to be easy to learn and packed with advanced features, enabling developers to create apps with less code and better code. SwiftUI allows you to focus on describing the UI you want, and it takes care of details like dark mode, dynamic type, and tracking changes in your model. This approach lets you share more of your code across more devices.

SwiftUI integrates seamlessly with the underlying OS and other frameworks, providing interoperability with UIKit and AppKit. This means you can use SwiftUI alongside existing views and view controllers from these frameworks, allowing for incremental adoption in existing apps.

Some key features of SwiftUI include:

• Declarative syntax for building user interfaces.
• Seamless integration with other Apple frameworks.
• Advanced customization options using modifiers and protocols.
• Support for animations, custom containers, mesh gradients, and scrolling customizations.
• Interoperability with UIKit and AppKit, enabling the use of gesture recognizers and animations across frameworks.

SwiftUI is used extensively within Apple for both new apps and new features in existing apps. It is also a key framework for building apps on new platforms like visionOS.
