In the WWDC 2025 session titled "Filter and tunnel network traffic with NetworkExtension," several new features and updates were introduced for the Network Extension framework. Here are some of the highlights:
-
URL Filtering: A new URL filtering API was introduced, allowing developers to create content filters that make accurate filtering decisions based on the full URL. This is done without revealing the URL contents to the app, ensuring privacy. The filtering process involves an on-device pre-filter and an off-device database server for URL lookups, with all exchanges protected to preserve privacy.
-
Any Hotspot Helper Extension API: This new API in iOS 26 allows apps to configure Wi-Fi settings and interact with Wi-Fi hotspots.
-
Local Push API: This API is designed for apps used on networks without access to the Apple Push Notification service, such as cruise ships or hospitals, enabling features like text messaging and voiceover IP calls.
-
VPN Enhancements: The session discussed improvements in managing VPN tunnels, including options for split and full tunnel VPNs, and the ability to enforce routing requirements to ensure VPN routes take precedence.
-
Security and Privacy: The Network Extension framework continues to focus on security and privacy, with features like encrypted DNS protocols and secure remote access options.
