Re-arrange NSArray/MSMutableArray in random order

Question

I\'m using NSArray/NSMutable array to store different objects. Once all the objects are added, I want to re-arrange them in random order. How can I do it?

Answer 1

Swift 4

let count = self.arrayOfData.count
for (index, _) in self.arrayOfData.enumerated()
{
  let nTempElement = count - index
  let swapIndexwith = (Int(arc4random()) % nTempElement) + index
  arrayOfData.swapAt(index, swapIndexwith)
}
