Swift 3 Versions not available in Cocoapods.

[Marxon13]

Currently pod trunk push and pod spec lint are failing. Working on a fix, there is no clear solution that I can find. I tried overriding the SWIFT_VERSION config property, but that is not working. As soon as a solution is found, I'll update Cocoapods.

Are you using Xcode 8 beta alongside other Xcodes?

I have faced the same problem with multiple Xcode. It seems like cocoapod can't figure build tools.

For now:

pod 'M13Checkbox' , :git => 'https://github.com/Marxon13/M13Checkbox.git'

@Marxon13 I can see that the code is updated, pod spec has been updated and I still get the 2.1.2 from cocoapods. are you sure you have pushed the latest to the pod trunk?

Same. ^

Turns out, it needed a swift-version file in the repo, along with having swiftenv installed.
