How Apple's Content Blocker API Enables Advanced Filtering on iOS

Apple's SFContentBlocker framework provides the foundation for content blocking on iOS, but its capabilities are often misunderstood. The framework allows extensions to define blocking rules in JSON format, covering URL filtering, cookie management, and content type restrictions. However, Wonder Blocker goes significantly beyond these basics by integrating its own AI-powered ad blocker engine. While the framework handles deterministic blocking rules efficiently through Safari's native content blocking system, the AI module extends protection by analyzing script behavior in real-time. This hybrid approach gives Wonder Blocker the speed of native content blocking combined with the adaptability of machine learning, providing comprehensive protection that static rules alone cannot achieve.
