I for one feels like the ternary operator still has a future with Swift.
If the discussion with ternary will go on though, I would like to weigh in a suggestion:
let a | x == y = a
| otherwise = b
let b | colour.Red = 0xff0000
| colour.Green = 0x00ff00
| colour.Blue = 0x0000ff
| otherwise = 0x000000
My rule of thumb for a style like this is that if you can read it as if it was English (read | (bar) as "when", | otherwise (bar otherwise) as "otherwise" and = as "is" or "be"), you're probably doing something right.
