This is awesome!
Could you adjust the indentation to match the existing source file please? (2 SPACEs) Makes the diff easier to read and makes the code fit in with the rest of the project.

I added code and commented out a faulty assertion to handle a mysterious crash that resulted from disconnecting devices from a macOS client. I had several crash reports that share this backtrace, and I finally reproduced it while connected to Xcode and found that buffer_size == 0 and done == true when a device disconnects. We get into this block of code where assert(buffer_size == sizeof(ref_upacket.size)), and the macOS client crashes. This assertion doesn't seem necessary. If there's no data and no error and GCD says we're done, then this is really just a no-op, and we should just return from the block rather than crash.
