Hi,

I’m a newbie to SWIFT and XCODE.

So far I was lucky to get some examples running with Vapor and PerfectSwift.

One annoying problem sucks, but I’m sure I get some help here, cause it looks like a basic problem 🙂

Every Swift source which needs Postgres fails with the following compile error ?!

Any hint is welcome!
