QUIC

struct · iOS 26.0+ · SDK 27.1

struct QUIC

The system definition of the QUIC protocol. Conforms to MultiplexProtocol, exposing configuration for a multiplexing instance of QUIC, which in turn exposes the ability to handle multiple streams of data over QUIC.

init · iOS 26.0+

init

TypeScript

static init(alpn: Array<string>): QUIC

Swift declaration

init(alpn: [String])

Create a QUIC protocol for use in a protocol stack. The application layer protocol negotiation (ALPN) tokens describe the application protocol in use above QUIC. - Parameter alpn: An array of application layer protocol tokens to use for negotiation during the QUIC handshake.
