If you mean the new UIKit API for managing controller lifecycle as part of SwiftUI adoption, the relevant update is in What’s new in UIKit (WWDC25).
UIKit is adding newer architectural support to make SwiftUI and UIKit coexist more seamlessly, including:
- SwiftUI scenes in UIKit apps via a new delegate protocol
- Better support for incremental SwiftUI adoption
- APIs that help UIKit apps participate in scene-based lifecycle more naturally
If you’re asking specifically about a controller lifecycle API, the context points more to lifecycle-related improvements in UIKit transitions and callbacks in Enhance your UI animations and transitions (WWDC24), where UIKit view controller lifecycle and appearance callbacks are discussed during transitions.
So the short answer is:
- For SwiftUI adoption in UIKit apps: new scene/delegate APIs in What’s new in UIKit
- For controller lifecycle behavior: UIKit view controller lifecycle and callbacks in Enhance your UI animations and transitions
If you want, I can narrow it down to the exact API name or the most likely session chapter.
