To write a UIKit app with Swift, you can start by leveraging the new features and improvements introduced in the latest iOS SDK. At WWDC 2024, Apple highlighted several enhancements in UIKit, particularly in the session titled "What’s new in UIKit." Here are some key points to consider:

  1. Adopt New UIKit Features: Utilize the improvements in transitions, animations, tab bars, and the new document launch experience. These enhancements can help streamline your app's user interface and make it more engaging.

  2. Integrate SwiftUI: UIKit now offers more integrations with SwiftUI, allowing you to combine the strengths of both frameworks. This can be particularly useful if you want to take advantage of SwiftUI's declarative syntax while maintaining UIKit's imperative approach.

  3. Explore New APIs: The session also introduced new APIs and general enhancements that can be adopted to improve your app's functionality and user experience.

For a more detailed overview of these features, you can refer to the session What’s new in UIKit (00:00:07).

Additionally, if you're interested in how UIKit and SwiftUI can work together, the session "Platforms State of the Union" discusses the interoperability between these frameworks, highlighting how gesture recognition and animations have been factored out to allow seamless integration. You can explore this further in the Platforms State of the Union (00:38:32).

By combining these insights, you can effectively write a UIKit app using Swift, taking advantage of the latest tools and frameworks provided by Apple.
