Assumptions: 

The instructions are pretty straightforward. I am not making any assumptions.

Test Cases:

[1, 2, 3, 4] - if it works with one it should work with all of them.

Implementation:

I will write a for loop that contains a switch statement with multiple cases. Each case will be an index. For each case I will
take the index out, multiply all of the integers left in the array and append the the new array into an empty array I will have
made at the start of the function.

//Seeing as the instructions wanted me to return the product of all the integers in the array EXCEPT the one at that index, you'll see that I cheated a bit.
//Also, my implementation changed quite from what it was at first.
func getProduct2 (for intArray: [Int]) -> [Int] {
    var product = 1
    var newArray : [Int] = []
    var array = intArray
    while array.count != newArray.count {
        let removedIndex = array.removeFirst()
        for index in array {
            product *= index
        }
        array.append(removedIndex)
        newArray.append(product)
        product = 1
    }
    return newArray
}
getProduct2(for: [3, 2, 3])
