I’m using Apple’s new Network framework to send my data (I believe they are working with the IETF on that), so no more BSD socket API. My TCP reader/writer is around 100 lines (have not implemented UDP). Packet analyzer is larger of course.</div><div class=""><br class=""></div><div class="">One Swift pain point is generating arbitrary packets. In C you can just send a struct out a network interface. But Swift does not guarantee the layout of native-Swift Structs, particularly Structs with arrays. Swift also does not have arrays of predefined sizes.</div><div class=""><br class=""></div><div class="">For simple structs with no arrays/strings, it works to create the Struct natively in Swift and spit it out the network interface (at least for Swift 4.2).. But whenever I have a struct with an array or String, I have to define the struct in C and import it into Swift. This makes it “difficult” to layout the packet in Swift, although I’m now past that challenge.</div><div class=""><br class=""></div><div class="">I remember looking at the Netrek source code back in 1991. I was impressed, but the C was mostly beyond my abilities. I looked at it again recently. It's still beyond my abilities. Swift just works better with the way my brain is wired.
