VPN

Use this skill for Apple-platform VPN work: host app configuration, packet tunnel app extensions, NetworkExtension preferences, TunnelKit integration, OpenVPN/WireGuard provider configs, entitlements, lifecycle debugging, and App Store/release readiness.

Default to iOS 15+ and Swift concurrency examples when the deployment target is unknown. Treat the VPN as two processes: the host app installs and controls a VPN profile; the packet tunnel extension owns protocol connection, packet I/O, network settings, and tunnel teardown.
