I have this:
var alphabet = ["a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"]
println("You should know your \(alphabet)'s")
How do I access a, b, c?
I've tried \(alphabet[0...3])'s and \(alphabet['0', '1', '2'])'s and \(alphabet[0,1,2)'s to no avail.
What am I missing?
You were on the right track with alphabet[0..2], but what you were missing is the join function which concatenates strings using a separator:
let alphabet = ["a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"]
let section = alphabet[0...2]
let s = join(", ", section) // Separator goes in the ""
println(s) // a, b, c
Also, there is no reason to use var for the alphabet so use let
join function isn't mentioned in the array tuts/docs that I've come across, and I've looked at a number of them. I really appreciate it.
