Swift Beta performance: sorting arrays

I was implementing an algorithm in Swift Beta and noticed that the performance was very poor. After digging deeper I realized that one of the bottlenecks was something as simple as sorting arrays. The relevant part is here: let n = 1000000 var x = [Int](repeating: 0, count: n) for i in 0..<n { x[i] = random() } // start clock here let y = sort(x) // stop clock here In C++, a similar operation take
