Today I bought "Server Side Swift with Vapor" from Ray Wenderlich to get me off the ground from a programming perspective. While I have a programming degree (long, long, long ago at Glasgow University), I don't have experience of developing in Swift 4.x - kind of a downer when I'm trying to build an app & service based upon it!
I'll post some musings as I work my way through the book, however as they say it's time to roll up my sleeves and start coding - stay tuned :)
