2. New Controls API: iOS has become more customizable with the introduction of a new Controls API. This allows developers to create controls that can toggle settings, execute actions, or deep link to specific experiences. These controls can be added to the control center or assigned to the action button on the iPhone 15 Pro (Platforms State of the Union).

3. UIKit Enhancements: The UIKit has seen improvements in transitions and animations, tab bars, and a new document launch experience. These features enhance the integration of UIKit and SwiftUI in apps (What’s new in UIKit).

4. Gaming Advancements: With the advancements in Metal and Apple silicon, iOS devices like the iPhone 15 Pro can now support console-class gaming experiences, offering a unified gaming platform with scalable hardware architecture (Platforms State of the Union).
