I dunno about #1 or #2, but for #3 look into the “Custom…” family of
protocols, especially ‘CustomStringConvertible’, which is the one that
defines ‘description’ and ‘debugDescription’ as having more-or-less
their Obj-C meanings. IIRC, CustomStringConvertible is also the one
that allows your custom type to participate in string interpolation:
“\(variableOfYourType)”, which would connect you with what I assume
you mean by “printing".
The standard protocols are all documented in the Swift Standard
Library document for Swift 2. It’s worth browsing the list to see if
there’s other stuff that might be helpful. Any of the “…Convertible”
protocols might open up possibilities for streamlining your invocation
syntaxes.
Will give it a crack, thanks. (Just discovered the amazing answer to #1,
so am off to play with that first.;)
