CocoaPods

What is CocoaPods
    CocoaPods manages library dependencies for your Xcode projects.

    The dependencies for your projects are specified in a single text file called a Podfile. CocoaPods will resolve dependencies between libraries, fetch the resulting source code, then link it together in an Xcode workspace to build your project.

POD
    command line tool to work with pod files

Installation
    sudo gem install cocoapods

    pod required ruby installation. checko ruby version
        ruby -v

    to maintain pod local repository use
        pod setup
            this will create master repo in user-> name-> .cocoapods -> repos...
            i think this is lile maven repo. we can maintain repo from local rather than downloading same repo.
            this is the main repo path
                https://github.com/CocoaPods/CocoaPods

add pod in to project
    pod init
        to init pod it needs a xcode project. without project no pod init ;)
        this will create a pod file.

open pod file using text editor
    use xcode interminal use this command
        open -a Xcode Podfile

adding required library projects as this
    pod 'JLocationKit', '~> 1.0.3'

downloading lib projects
    pod install

update missing pods
    pod install --repo-update

to run pod project open xcode using App.xcworkspace
    do not open using project file

remove pod from a project
    $ sudo gem install cocoapods-deintegrate cocoapods-clean
    $ pod deintegrate
    $ pod clean

    $ rm Podfile
