Bubble sorting an array in Swift, compiler error on swap

Question

I wrote a really simple bubble sort for a card game. It takes an array of \"Card\" objects, each of which has a an \"order\" attribute which indicates the value to be sorted

Answer 1

Swift 5: Generic bubble sort method,

func bubbleSort(with array: inout [T]) -> [T] {
    for i in 1.. array[j+1] {
            array.swapAt(j, j+1)
        }
    }
    return array
}

Input:-

var intArray = [8, 3, 5, 10, 4, -1, 17, 3, 18, 10]
var floatArray = [12.231, 12.23, 14.5, 3.4, 67.899, 0.0, -1.234]
var doubleArray = [123.43555, 123.1223332, -121.2212, 23.343434, 1.232434]
var stringArray = ["Ratheesh", "Srini", "Thangu", "Muthu", "Gopi"]

print(bubbleSort(with: &intArray))
print(bubbleSort(with: &floatArray))
print(bubbleSort(with: &doubleArray))
print(bubbleSort(with: &stringArray))

Output:-

[-1, 3, 3, 4, 5, 8, 10, 10, 17, 18]
[-1.234, 0.0, 3.4, 12.23, 12.231, 14.5, 67.899]
[-121.2212, 1.232434, 23.343434, 123.1223332, 123.43555]
["Gopi", "Muthu", "Ratheesh", "Srini", "Thangu"]
