How to install CocoaPods?

CocoaPods is the dependency manager for Objective-C projects. It has thousands of libraries and can help you scale your projects elegantly. It is built with Ruby and is installable with the default Ruby available on OS X. To check ruby version installed on your system, run the following command in Terminal:

$ ruby -v

You’d better update the ruby to latest version using the command:

curl -sSL https://get.rvm.io | bash -s stable --ruby

To install a ruby built application, the RubyGems software also called “gem” can be used

$ sudo gem install cocoapods

You’re almost done and now can sit back relax and see the successful command execution similar to the following:

And when new version is available, it is notified in terminal upon executing the command ($ pod install) as (CocoaPods 0.34.2 is available) so same install command can be used to update it.

$ sudo gem install cocoapods

Now that you know how to install cocoapods, you would like to use iOS Libraries via cocoapods.
