Failing to install danger-swift via HomeBrew

Failing to resolve dependencies.
What can I do?
Is this due to my local environment?

Also failed on Bitrise container. It is not my environment's problem, I think.

Weird, nothing's changed on marathon or Danger Swift for the last few days

@orta Does it work fine on your mac? Please tell me if you need more information to investigate.
