Initializers in native arrays in swift

Question

I am just getting started with swift and I know we have a default array initialiser in swift and the syntax goes like this:

    let myArray = [Int](count:3 , repeatedValue:2)//int types [2,2,2]

But when I remove [Int] from the statement,it initialises the array with values (3,2).

    let myArray = (count:3 , repeatedValue:2)//[3,2]

Can anyone explain this behaviour?

In the second example, you're getting a tuple, not an Array. If you don't want to specify [Int], you still need to specify Array, like this:

let myArray = Array(count: 3, repeatedValue: 2)

Learn more about tuples in the Swift book.
