How can I run my performance tests more than ten times?

Question

By default Xcodes performance tests are run ten times and my result is the average of those ten tests. The problem is the averaged result varies considerably each time I run it

Answer 1

I typically expand the Standard Deviation value to include the range I'd accept.

One obvious workaround for you is to perform the operation 5 times within the measure block you are executing. (You'll want to change the expected time.)

    measure {
        for _ in [1...5] {
            // ...
        }
    }
