<string>Looking for local tcp Bonjour service</string>
<key>NSBonjourServices</key>
<array><string>_some-service._tcp</string></array>
The dot "." at the end of "_some-service._tcp" is not required in .plist but is only required when searching for service using
[nsNetServiceBrowser searchForServicesOfType:@"_some-service._tcp." inDomain:@""];
inDomain parameter should empty to search service in all domains including local.
I hope that helps.
