Networking & Connectivity

14 frameworks

The Networking & Connectivity frameworks provide the APIs your app uses to send and receive data across networks and to discover and communicate with nearby devices. They span modern transport-level connections over TCP, UDP, and TLS; peer-to-peer links over Wi-Fi and Bluetooth; and inspection and configuration of network paths, reachability, and interfaces. Higher-level frameworks add system extensions such as VPNs and content filters, device-to-device messaging, and discovery of local services and peers.
