How to get CPU time used by a function in Swift

Question

I want to get the CPU time used by a function in Swift. In C we could do this by clock() function. I read this answer but it measures the real time. Any suggestions?

Swift has `clock()`. Just import `Darwin` (or `Foundation` or `UIKit` which all import `Darwin` eventually). — Rob Napier, Oct 15 '15 at 13:37

You can use the clock() function from C:

import Foundation
var t = clock()

myLongRunningFunction()

t = clock() - t

print("The function takes \(t) ticks, which is \(Double(t) / Double(CLOCKS_PER_SEC)) seconds of CPU time")
