CodePilot for Xcode 9

[antmd]

Hi,

I rewrote parts of CodePilot so it works with Xcode 9. It's available here: https://github.com/antmd/CodePilot/blob/master/README.md

It still needs some work to get all of the symbol functionality back to the original, but I haven't much time. It should be quite easy, now the approach for Xcode 9 is clear in the new code.

My main use case is the new 'switcher' function I added.

Do you think I should attempt a pull request, or rename the repo to something else (but still provide a link to this version)?

Best Regards
