Swift's implementation of arrays is throwing me for a loop again! (Haw, haw.) All I want is to take an array of arbitrary length and get a new array (or an array slice) from it that has the first element removed.
Why is this so hard?
I just want to be able to do something like this:
let suffix = someArray.suffixFrom(1)
But I can't figure out how to do this. It seems the closest method I've found requires knowing the length of the array, which I don't know because it's computed inline and I really really hate having to split such a simple concept up into a bunch of variables and lines.
I have a string split by colons (:) and I just want to create a
containing all the :-delimited components excluding the first one.
So that a string "one:two:three" would return a set containing ["two", "three"]. Since I can create a Set from an array, all I really need is to get the suffix of the array, but I don't know how many components there are because it's inline:
Why does Swift make this so hard?
Before a bunch of you suggest it, I'm well aware I could extend the array class to do this myself, but I'm writing a framework and I don't want to do that, and I also don't want to have to write a bloody utility function to do something so darned simple.
