create a function that implements bubble sort in swift

main.swift
func bubbleSort(_ array: inout [Int]) {
    guard array.count > 1 else { return }

    for i in 0..<array.count {
        var swapped = false
        for j in 1..<array.count-i {
            if array[j] < array[j-1] {
                array.swapAt(j, j-1)
                swapped = true
            }
        }
        if !swapped { return }
    }
}
