CocoaPods

What is CocoaPods

CocoaPods is a dependency manager for Swift and Objective-C Cocoa projects. It has over 45 thousand libraries and is used in over 3 million apps. CocoaPods can help you scale your projects elegantly.

• Install
• Get Started
• Create a Pod

CocoaPods is built with Ruby and is installable with the default Ruby available on OS X. 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.

# Xcode 8 + 9
$ sudo gem install cocoapods

We also have a Mac app for CocoaPods. It only gets major releases ATM though.
