CocoaPods Deploy is a plugin which tries to mimic the behaviour of bundlers --deployment mode.
The goal is to download and install the specific dependency versions from the Podfile.lock without having to pull down the full CocoaPods specs repo.
$ gem install cocoapods-deploy
$ pod deploy
This will look at the dependencies in your Podfile.lock and will install them up to 85% faster than pod install. If you don't have a Podfile.lock then you will still need to run pod install and pod update first.
