It works when one device is only a publisher and the other is only a subscriber. However, when both devices act as both publisher and subscriber simultaneously—which Apple’s documentation (https://developer.apple.com/documentation/wifiaware/adopting-wi-fi-aware#Declare-services) indicates is valid—the connection never establishes. After timing out, both NetworkListener and NetworkBrowser transition to the failed state. This appears to be a race condition in Network framework.
Task.detached {
try await NetworkListener(
for: .wifiAware(
.connecting(
to: .myService,
from: .allPairedDevices,
datapath: .defaults
)
),
using: .parameters {
Coder(
sending: ...,
receiving: ...,
using: NetworkJSONCoder()
) {
TCP()
}
}
).run { connection in
await self.add(connection: connection)
}
}
Task.detached {
try await NetworkBrowser(
for: .wifiAware(
.connecting(
to: .allPairedDevices,
from: .myService
)
),
using: .tcp
).run { endpoints in
for endpoint in endpoints {
await self.connect(to: endpoint)
}
}
}
