Apple introduced a new Foundation Models framework and a Core AI framework to give developers more control over on-device AI. The update adds image input support, meaning apps can now process images and text together. Developers can also use server-side model execution and custom skills to better integrate AI capabilities into their software.

Xcode is receiving a major overhaul to support agentic coding workflows. The coding assistant now handles app localization and interacts directly with simulated devices. Craig Federighi claims these changes make Xcode the best environment for building apps. Developers can also resize and interact with app previews more easily during the design process.

Expanded App Intents support allows third-party apps like Line to integrate more deeply with Siri. Users can now ask Siri to perform specific actions within these apps on their behalf. This shift moves Apple toward a more open ecosystem where AI agents handle tasks across different applications rather than relying on single-app interfaces.

These tools collectively streamline how developers build AI-driven features. By combining on-device processing with server-side flexibility, Apple is reducing the friction for creating complex agentic behaviors. This update transforms Xcode into a hub for AI-assisted development and deeper system integration.
