Add an error/warning for old CocoaPods versions

[tjvantoll]

@fealebenpae helped me through an issue with CocoaPods, where the problem ended up being that I was using an older version of CocoaPods.

Is it possible (and a good idea) to have tns doctor and/or tns plugin add show an error when the user is using an older version of CocoaPods? For now I think we'd want to require 0.38.x+.

Let me know what you think. And thanks.

Hi @tjvantoll
I like the idea and it sounds reasonable. I'm wondering what is the best way to check the version of CocoaPods? If I try gem which cocoapods I receive something like:
/Library/Ruby/Gems/2.0.0/gems/cocoapods-0.35.0/lib/cocoapods/rb - is the 0.35.0 the version that we have to verify? Do you have any idea for another command that will give is the version of the cocoapods?

What about pod --version?

What about pod --version?

👍 That's what I've been using.

Ok, thanks, I've added it to 1.4.0 milestone.
