What does the program print?

SWIFT

let scores = [7, 9, 4]
var position = 0
for (i, _) in scores.enumerated() {
    position = i
}
print(position, scores.count)

2 3

Expecting 3 3: numbering the elements from 1. enumerated() starts at 0, so the last number in an array of three elements is 2.
Expecting 4 3: thinking the tuple holds the element first and the number second. The number comes first, so i gets 0, 1 and 2.

What does the program print if the loop is for (_, x) in scores.enumerated() with position = x?
How would you print each element together with its place counted from 1?
