An implementation of the Swift Service Discovery API using DNS-based Service Discovery (DNS-SD), also known as Bonjour, Zeroconf or Avahi.
Uses the dns_sd library, which on macOS/Windows is provided by Bonjour and on Linux requires the Avahi compatibility layer. On Ubuntu, the following package can be used:
sudo apt install libavahi-compat-libdnssd-devThe library draws inspiration from

The following documentation on the dns_sd library was also incredibly helpful:
- Apple's documentation archive, describing the low-level DNS-SD API
- DNS Service Discovery on Windows, providing an example-oriented overview of the library and an explanation of how the callbacks are driven
