protocol WAService : CustomStringConvertible, Decodable, Encodable, Hashable, Identifiable, Sendable

A protocol that defines a service that a device can publish or subscribe to. A service represents a specific function or use case that's performed over Wi-Fi Aware. Services are specific functionality and protocols that your app can publish or subscribe to on other devices. Services are identified by a service name string that follows the rules in [RFC 6763](https://datatracker.ietf.org/doc/html/rfc6763#section-4.1.2) and [RFC 6335](https://datatracker.ietf.org/doc/html/rfc6335#section-5.1). For a service name of `example-service`, the full service name encoded in the `Info.plist` and sent over the air is either `_example-service._tcp` if using the TCP protocol or `_example-service._udp` if using any other protocol. You must register your app with a unique name in the [IANA service name registry](https://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xml) to avoid conflicts with other apps and devices. If you have an invalid service name in the `Info.plist`, your app crashes.
