This is the sort of thing a good stream API should be able to handle efficiently, i.e. methods to read/write various binary data types like integers. Or alternatively, an API to encode/decode those types into an ArraySlice (like Go’s encoding/binary package.) 

Hopefully these can be added to the Swift standard library. In the interim, something like that Go package could be implemented with some small C functions callable from Swift.
