I am proposing that my attempt to wrap a compiled library was doomed to failure.
I am guessing that when Swift finds the "header.h" file referring to a lot of functions it cannot see in the available source code it determines the header file is wrong... and no correspondence will be entered into. There may be a better error message for this but I'll let others decide.
Give something over 100 views I feel comfortable that there is no newby gotcha on my part, and therefore no easy fix. So thank you for looking.
I do have access to the source (after all I am complaining the server from source), bit it is a formidable exercise splitting out what is needed. Luckily this has been done already:
decision-labs / libpq.framework,
It's a bit old but the fundamentals haven't changed. So my immediate problem has a solution.
The more general problem of taking an arbitrary binary library where source is not a available is discussed here:
Recipe
recipe and how-to for code signing
I haven't worked through these solutions since I'm heading for the source code route, but someone else may benefit.
