Shuffle array swift 3
Как я могу преобразовать функцию ниже вswift 3? В настоящее время получаюBinary operator '..<' cannot be applied to operands of type 'Int' and 'Self.IndexDistance' ошибка.
extension MutableCollection where Index == Int {
/// Shuffle the elements of `self` in-place.
mutating func shuffleInPlace() {
// empty and single-element collections don't shuffle
if count < 2 { return }
for i in 0..<count - 1 { //error takes place here
let j = Int(arc4random_uniform(UInt32(count - i))) + i
guard i != j else { continue }
swap(&self[i], &self[j])
}
}
}
