Swift 3 / xcode 8

[truemetal]

It looks like Swift 3 / xcode 8 support is missing
This prevents the pod from being used on the latest environment

Thanks for the feedback. I'm on it. Having some troubles with pods validation right now, though. Don't know if it's an XCode 8-thing or what, hopefully it'll be fixed soon.

@truemetal So, I think I've gotten it to work. But use the swift3 branch when installing the pod, like so:

pod "Keychain", :git => 'https://github.com/pkrll/Keychain.git', :branch => 'swift3'

I'll merge the two branches when Cocoapods releases a stable version that fixes the Xcode 8 bug.

@pkrll thanks!
