Setup CocoaPods for Swift project

Cocoa Pods provides a standard way to manage dependent libraries. It only takes a few steps to set it up in a Swift project:

• Assume you've already have a normal Xcode project
• Open terminal window, $ cd to your project directory
• Create a Podfile by runing $ pod init
• Edit the Podfile to add any liberties you want to install within certain target
• Make sure to uncomment use_frameworks if it's a Swift project
• Run $ pod install
• An xcworkspace project should be created, please use it to load your project moving forwards
