Apple's new Foundation Models framework in iOS 26 enables developers to integrate on-device AI capabilities directly into their apps using Swift. The framework provides access to the same language models powering Apple Intelligence, ensuring privacy by processing everything locally without internet connectivity. Developers can build features like content generation, question answering, and conversational assistants using the SystemLanguageModel class. The tutorial demonstrates creating an "Ask Me Anything" app that showcases both complete and streaming response generation, session management for context preservation, and proper UI handling during model processing.
