maxArray Function problem! ASAP!!

I need to solve this problem! can anyone help?

Use for-in statement to complete the maxArray function that receives integer array and returns the maximum number. 

func maxArray (numbers:[Int]) -> Int {

}

let arrayToMax = [43, 56, 12, 23, 87, 27, 98]
let maxNum = maxArray(arrayToMax)

Here you go:

func maxArray (numbers:[Int]) -> Int {
    var max = 0

    for n in numbers {
        if n > max {
            max = n
        }
    }
    return max
}

let arrayToMax = [43, 56, 12, 23, 87, 27, 98]
let maxNum = maxArray(arrayToMax)

can I skip stating

let arrayToMax = [43, 56, 12, 23, 87, 27, 98] let maxNum = maxArray(arrayToMax)

these codes?

There I fixed my answer.

No you need those for the function to work. Meaning it needs to evaluate from somewhere, in this case is using the array.

            <p>struct Queue {
    var queueArray:[String] = []
    mutating func enqueue (element:String) {
        (-----------------------------)
    }
    mutating func dequeue() -> String {
        (-------------------------------)
        (-------------------------------)
        return returnValue
    }


var newQueue = Queue()
newQueue.enqueue("Leonard")
newQueue.enqueue("Sheldon")

newQueue.enqueue("Penny")
newQueue.enqueue("Howard")
newQueue.enqueue("Rajesh")
let firstOne = newQueue.dequeue()</p>
            ```


I don't know what should go on the blank line to make codes work
