Craig Federighi on how Apple helps developers make the most of the iPhone Duo [Video]
Apple software chief Craig Federighi discussed how developers can utilize the new hinge mechanism in the iPhone Duo through a dedicated API. The API allows developers to access the device's pose and hinge angle with high accuracy to create adaptive user experiences. Federighi emphasized that Apple's high-level frameworks and agentic coding tools help automate the adaptation of existing apps to this new form factor.
- ▪Apple provides an API that allows developers to read the iPhone Duo's hinge angle with an accuracy of approximately five degrees.
- ▪The API communicates the device's pose, such as book, on-table, or tent mode, to enable consistent app behavior without requiring raw degree data.
- ▪Apple uses the hinge angle internally for features like the outer screen defocusing into a preview of the inner display as the phone opens.
- ▪High-level frameworks like UIKit and SwiftUI automatically adapt many apps to the new device capabilities, reducing the manual work required for developers.
- ▪Apple supports agentic coding tools that can help developers adapt existing applications to the iPhone Duo almost automatically.
