Swift add all elements from array together

I have an array of numbers and I want to iterate through all of the elements in that array and add together all of the integers. Here is the function I have so far:

func addTogether(array:Array<Int>, divide:Int) -> Int
{
    var a = 0

    while a < array.count
    {

    }

    return 0
}

I know that I'm probably going to have to do this inside of the while loop. Can anyone give me some guidance as to where to go from here? Thanks!

No loop needed. Use reduce, like this:

let sum = array.reduce(0,+)
