Apple platforms have multiple Bonjour APIs. The one I generally recommend is Network framework.

Having said that, your requirements don’t seem to match a typical Bonjour use case. Your post suggests that you’re building a Bonjour diagnostic product rather than a typical Bonjour product. For example, most Bonjour products want to advertise and browse for a specific service type but it sounds like you want to browse for all service types.

If so, I have two suggestions for you:

You’re probably better off working with the low-level <dns_sd.h> API. A good place to start with the API is the DNSSDObjects sample code.
Browsing for all service types requires the multicast entitlement, per FAQ-3 of the Local Network Privacy FAQ
