I'm not at all familiar with the Apple development ecosystem, but since Swift has been open-source, why not run the swift version on all platforms? There are vast differences in the implementations of C++ and Swift, even if both are compiled to native machine code. That aside, given the hype behind Apple devices, I'm sure there have been loads of benchmarks published already. What I would personally be more interested in, would be to see how the A9X fares against Intel's Core M's, which have a similar power envelope.

A version which shows the iPad performance crushing the Macs, not because of CPU performance but because of some kind of Swift performance regression on desktop, would not have been interesting
