iOS: onDiscoveryStartFailed

[robert-virkus]

Hi, is there anything I need to set up on iOS for being able to start scanning?

My code:

nsd.enableLogging(nsd.LogTopic.calls);
nsd.enableLogging(nsd.LogTopic.errors);
nsd.startDiscovery('_ds-prov._tcp').then((discovery) {
// ...
});

log output:

[MethodChannelNsdPlatform] [2022-04-25 16:50:18.712895] [calls] Call: startDiscovery {handle: d4dd15f0-6bf0-4e4f-9ba3-bf789c808402, service.type: _ds-prov._tcp}
[MethodChannelNsdPlatform] [2022-04-25 16:50:18.731574] [calls] Callback: onDiscoveryStartFailed {handle: d4dd15f0-6bf0-4e4f-9ba3-bf789c808402}

The same code works fine on Android, on iOS I receive the above log output: onDiscoveryStartFailed.

Many thanks in advance and thanks for your cool nsd library!

I was missing the following settings in my Info.plist file:

<key>NSLocalNetworkUsageDescription</key>
<string>To discover network devices via mDNS</string>
<key>NSBonjourServices</key>
<array>
	<string>_ds-prov._tcp</string>
</array>

It would be useful to mention this in your readme (not with this specific service type, of course).

Thanks again for your library!

Yes, you're absolutely right, I'll add this to the README.

I've updated the documentation and put the permission chapter in a more prominent place. Also, I added the permissions to the iOS version of the example app. Tests are green and the new version is out (1.5.0) so I'm closing this. Thank you for your contribution 🙂
