It compiles in Swift... but what is it?

I mistakenly typed something like this in Swift:

var a = [Int, Int, Int]()

and it compiles... but I have no clue what this can represent...

Any ideas? Can someone explain the semantic meaning of it?

Thanks, happy coding to all,

It's an array of tuples of type (Int, Int, Int) Consider the following:

var a = [Int, Int, Int]()
a.append(12, 1134, 124)
var first = a.first!
first.0 //= 12
first.1 //= 1134
first.2 //= 124
