Anything I should be aware of on WWDC25 if I'm currently working on a project targeting iOS16?

If you're currently working on a project targeting iOS 16, there are several updates from WWDC25 that you should be aware of:

Design Updates: Apple introduced a new design system called Liquid Glass, which offers a more fluid and expressive experience across apps and platforms. This could be an opportunity to refresh and modernize your app's design to align with the new aesthetics.
Apple Intelligence: There are new features related to Apple Intelligence, which allow apps to leverage on-device large language models for enhanced functionality, even offline. This could be beneficial if you're looking to integrate more intelligent features into your app.
Xcode 26: The latest version of Xcode includes new tools and optimizations to help you be more efficient in writing and debugging code. It also supports the new design system and provides tools for testing and distributing your app.
Swift and SwiftUI Enhancements: There are updates to Swift and SwiftUI that improve performance and capabilities. If your app uses these frameworks, you might want to explore the new APIs and features to enhance your app's functionality.
UIKit Improvements: UIKit has been updated with new features for modern patterns and deeper SwiftUI interoperability. This includes built-in support for Swift observable objects and automatic observation tracking, which could simplify your code and improve performance.
SceneKit to RealityKit Transition: If your project involves 3D graphics, note that SceneKit is deprecated, and Apple recommends transitioning to RealityKit for new possibilities in apps and games.
Concurrency in Swift: Swift 6.2 introduces improvements for writing concurrent code, making it safer and easier to manage. This could be particularly useful if your app involves complex data processing.
