First up, terminology: I’m going to use the term accessory to refer to the hardware you’re trying to talk to (because device is already ‘taken’ by your iOS device).

Next, the best way forward here very much depends on the features of your accessory. For example:

If your accessory includes a mini web server, you should talk to it via
```
URLSession
```
.
If your accessory speaks a custom protocol over TCP, you should use
```
Stream
```
(or
```
NWConnection
```
, if you’re OK with an iOS 12 beta dependency).
If your accessory speaks a custom protocol over UDP, I’d recommend that you use
```
NWConnection
```
even though it requires iOS 12 beta, because the alternative, BSD Sockets, is distinctly un-fun to use from Swift.
If your accessory implements Bonjour technologies [1], you can use
```
NetServiceBrowser
```
to find the accessory on the network.
