how to get number of maximum element in array in swift

Question

How to solve it? I should get 2 in this case.

var r = [1, 3, 5]
r.max() // gives 5

ps: new quality standarts when posting - is something crazy...

This is how I would go about doing it:

let array = [1, 3, 5]

if let (maxIndex, maxValue) = array.enumerated().max(by: { $0.element < $1.element }) {
    print("The max element is \(maxValue) at index \(maxIndex)")
}
else {
    print("The array is empty, and has no max element or index.")
}
