CocoaPods is built with Ruby and is installable with the default Ruby available on macOS. We recommend you use the default ruby. Using the default Ruby install can require you to use sudo when installing gems. Further installation instructions are in the guides. $ sudo gem install cocoapods

Search for pods (above). Then list the dependencies in a text file named Podfile in your Xcode project directory: platform :ios, '8.0' use_frameworks! target 'MyApp' do pod 'AFNetworking', '~> 2.6' pod 'ORStackView', '~> 3.0' pod 'SwiftyJSON', '~> 2.3' end Tip: CocoaPods provides a pod init command to create a Podfile with smart defaults. You should use it. Now you can install the dependencies in your project: $ pod install Make sure to always open the Xcode workspace instead of the project file when building your project: $ open App.xcworkspace Now you can import your dependencies e.g.: #import <Reachability/Reachability.h>
