How to create your own CocoaPods framework

Hello Everyone,

I hope you are well aware with CocoaPods and how to use this inside your XCode projects. If you are not well aware, follow my previous blog about how to use CocoaPods.

Now it is time to learn to build your own Pod framework.

Setup – What you need?

  • git account.
  • Make sure git is installed in your Mac machine. Because we will do all git commands from terminal only. (using source tree or any other application for git commands is not recommended)
  • Make sure your system is updated and you have latest Ruby Gems installed.
    $ sudo gem update --system
  • Install CocoaPods if you don’t have Pods installed in your Mac machine.
    $ sudo gem install cocoapods

Create your Pod framework

  1. Open terminal and redirect to desired folder where you want to put your Pod Framework.
  2. Create your framework with the command pod lib create. Here I am giving my Pod framework name ‘MZFacebookManager’.
  • $ pod lib create MZFacebookManager
This will ask you some series of questions. You can answer based on your choice. Like for my case I have given answers like this:
  1. What language do you want to use? [ ObjC / Swift ]
     - ObjC
  2. Would you like to include a demo application with your library? [ Yes / No ]
     - Yes
  3. Which testing frameworks will you use? [ Specta / Kiwi / None ]
     - None
  4. Would you like to do view based testing? [ Yes / No ]
     - No
  5. What is your class prefix?
     - MZ

Once you are done it will create the folder for MZFacebookManager. Inside this you can see structure like:

.podspec file at the root is important file. This will contains your Pod version, dependencies, git url etc with some other Pod descriptions. You can edit the details, version and also define dependencies if your Framework is using any other third party Framework. Like in my case, my Framework is using ‘FBSDKLoginKit‘ and ‘FBSDKCoreKit‘.

Once you are done with editing of podspec file you need to validate this file. You can do this with Pod lib lint command.

$ pod lib lint

Now open github website and create a new repository for MZFacebookManager (give your Framework name).

Screen Shot 2017-04-06 at 1.45.58 PMOnce it is created, go back to terminal again and push your code (You can also ignore this Push if you don’t want to push a default code on your git).

But if you want to push, just make sure once again your .podspec file is defined the correct url of git repository.

s.source = { :git => 'https://github.com/muzammil-triffort/MZFacebookManager.git', :tag => s.version.to_s }

Push your code on git: 

$ git push

This will push the default code of your Framework. Now open XCode again and add your Framework files.

  • Delete ReplaceMe file
  • Add your ObjC or Swift files (based on the project type you have chosen at the start)
  • Like i have added three files inside development i.e. MZFacebookManager.h, MZFacebookLoginManager.h and .m files. These files will show when you install the Pod Framework.

Once all files added and there is no error in your code. Update the version of your Framework by updating this inside .podspec file (0.1.1) and run lib lint command again to make sure everything is correct.

$ pod lib lint

When validation success, now first push the code on git by giving a tag.

$ git tag 0.1.1

$ git push origin 0.1.1

Push your Pods Spec

$ pod trunk push MZFacebookManager.podspec 
At first time you will get the error message to resgister your session:
[!] You need to register a session first. 
$pod trunk register muzammil@triffort.com 'Muzammil' --description='Testing'

Replace my email id and name with yours. This will send a verification link on your mail. Once you verified, you can continue with terminal.

$ pod trunk push MZFacebookManager.podspec 
If all goes well Pod spec successfully update on git and you can see it is showing the description and other Pod details on home page of your git repository.
You can also add –verbose in lib lint and trunk push command to see the detail result (in case of error).
If you open your github repository, you can see screen like this:

 Summary
# Create Library
pod lib create LibraryName
# Verify podspec
pod lib lint
# Push the podspec
pod trunk push LibraryName.podspec

Yeah! You are done with your first Pod Framework. It’s time to have some nice coffee.
