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

Question

I mistakenly typed something like this in Swift:

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

and it compiles ... but I don't know what that might represent ...

Any ideas? Can anyone explain the semantic meaning of this?

Thank you, happy encoding for everyone,

This is 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
