New Array from Index Range Swift

Question

How can I do something like this? Take the first n elements from an array:

newNumbers = numbers[0..n]

Currently getting the following error

Answer 1

One more variant using extension and argument name range

This extension uses Range and ClosedRange

extension Array {

    subscript (range r: Range) -> Array {
        return Array(self[r])
    }


    subscript (range r: ClosedRange) -> Array {
        return Array(self[r])
    }
}

Tests:

func testArraySubscriptRange() {
    //given
    let arr = ["1", "2", "3"]

    //when
    let result = arr[range: 1..
