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

Here is bubble sort implemented in swift 4.0.2

var array = [15,11,20,14,12,13,17,16,18,19]
var sortedArray = Array(array)
var sortedAboveIndex = array.count 

for i in 0 ..< sortedAboveIndex-1 {

  for j in 0 ..< sortedAboveIndex-i-1 {

      if (sortedArray[j] > sortedArray[j+1]) {

          sortedArray.swapAt(j, j+1)        
      }
  }

}

print(sortedArray)
