Cocoapods is a dependency manager for Swift and Objective-C Cocoa projects that allows developers to specify libraries and frameworks for their Xcode projects. It has over 10,000 pre-built libraries available and allows specifying library versions to avoid breaking changes. Cocoapods is installed via Ruby and generates a Podfile to define project dependencies which are then installed to a generated Xcode workspace. Common commands include pod init, pod install, pod update and pod search.

2. WHAT IS COCOAPODS
 According to Cocoapods.org:
 The dependency manager for Swift and Objective-C Cocoa projects
 Over ten thousand libraries and can help you scale your projects elegantly
 Built with Ruby and is installable with the default Ruby available on OS X
 Built for XCode
 You can specify a specific version of a library so that breaking
changes don’t break you

3. COCOAPODS COMPARED TO
 Gradle build scripts - .gradle files auto generated in Android
Studio. You don’t have to know much about Gradle to use it since
Android Studio does the heavy lifting for you.
 Maven – Great for Java projects, especially large scale cross
team projects.
 Cocoapods – De facto standard for iOS. Well supported
community,

4. SETTING UP COCOAPODS
 You will need Git set up
 You will need Xcode command line tools set up
 No need to brew it, just:
 sudo gem install cocoapods
 pod setup (one time set up)
 Create an Xcode project and change into the project root directory
(where your ProjectName.xcodeproj file is placed)

5. SETTING UP COCOAPODS
 From the project root directory:
 You can issue a pod init and a default podfile will be created. Or
 touch podfile
 open –e podfile
 Add some dependencies:
 pod 'AFNetworking', '0.9.1’
 Save the podfile
 pod install

6. SETTING UP COCOAPODS
 Open the workspace – not the project

7. POD COMMANDS
 pod help – get a detailed list of pod commands
 pod init - generate a Podfile for the current directory.
 pod install - install project dependencies to Podfile.lock versions
 pod search <search term> - search for an existing pod to use
 pod update - update outdated project dependencies and create
new Podfile.lock

8. PRE-BUILT PODS
 Large list of pre-built pods available from cocoapods.org
 Search capability and example code
 Can also use the pod search <search term> as previously
mentioned
