what did most interesting in that wwdc? for developers

At WWDC 2025, several exciting announcements were made that are particularly interesting for developers:

Apple Intelligence: This was a major highlight, introducing a personal intelligence system that integrates powerful generative models into iOS, iPadOS, and macOS. This system enhances capabilities for understanding and generating language and images, with a strong emphasis on privacy.
Foundation Models Framework: Developers can now use Apple's models to get responses in plain text or structured Swift Data, which can be integrated into apps for enhanced functionality.
Liquid Glass Design: A new design material called Liquid Glass was introduced, allowing developers to reimagine app aesthetics with a more fluid and intuitive user interface.
Xcode Enhancements: Xcode received updates with more generative intelligence, including predictive code completion and Swift Assist, which allows developers to interact with code using natural language.
Swift and SwiftUI Improvements: There were updates to Swift that make it easier to write safe and efficient code, and new APIs in SwiftUI to help build modern user interfaces across all Apple platforms.
VisionOS and RealityKit: Enhancements in VisionOS and RealityKit were also highlighted, providing new opportunities for developing spatial computing apps and games.

These innovations provide developers with powerful new tools and frameworks to create more intelligent, efficient, and visually appealing applications across Apple's ecosystem.
