Why CI/CD?

CI/CD (Continuous Integration/Continuous Delivery) streamlines software development by automating the integration, testing, and delivery processes, ensuring faster, more reliable, and efficient deployment of software updates. It enhances collaboration, accelerates time-to-market, and minimizes errors through automated testing and continuous feedback loops.

Jenkins Logo

Jenkins is an open-source CI/CD tool that helps automate tasks in terms of integration and deployment. Jenkins will be able to build → test → deploy the iOS application.

Jenkins ensures a reliable development pipeline by building the iOS application only when the associated test cases have successfully passed, maintaining the integrity and quality of the codebase.

Before getting into action, let’s understand GitHub and webhooks.

Configuring GitHub

Go to GitHub Repository and click on Settings


Click on Webhooks


Click on Add webhook

Add Webhook

Refer webhook sites such as hookdeck or webhook.site). At the end of the URL, add /github-webhook/. In the ‘Content type’, select application/json.

You can select the individual events. I selected Pull Requests/Pushes. Make sure that the ‘Active’ option is checked and click on ‘Add webhook’.



Installing Jenkins

Download the latest stable build from the official website. I have installed it using the HomeBrew package manager.

Once the installation is done, navigate to http://localhost:8080/, your Jenkins local address.

Configuring Jenkins for iOS

To unwrap the password, use the following on the terminal

    sudo cat /Users/YOUR_USER_NAME/.jenkins/secrets/initialAdminPassword

Unlock Jenkins

I have selected the ‘Install suggested plugins’ option in the next window.

Manage Jenkins

Select Manage Jenkins and then click Plugins in the options.

Manage Jenkins

Click on Available Plugins, select Xcode Integration and install it.

Xcode Integration

Creating a Jenkins Job

Jenkins Job

On Jenkins Dashboard, select New Item. Select Freestyle Project and provide a name to create a job.

Integrating Version Control

Click on the Source Management

Select Git and Add your Repository URL.

Source Code Management

Click on the Build Triggers to trigger the events. We can select the ‘GitHub hook trigger for GITScm Polling’ to check the webhook events.

Build Triggers

Now, our GitHub repository is integrated with the Jenkins project.

With GitHub and Jenkins integration, we can trigger the Jenkins job to run with every commit.

Xcode Integration Plugin with Jenkins

Go to Build Steps → Add Build step → Xcode

Build Steps

In General build settings, update the necessary fields.

General Build Settings - Xcode

Check the Pack application, build and sign .ipa

Advanced Build Settings

If you need to enter values for advanced build settings in Xcode, you can do so by filling out the fields related to the workspace.

Advanced Build Settings

Move to Jenkins Dashboard > Manage Jenkins > System

This will help to configure the Xcode Builder. Add Team Name and Development Team ID.

Xcode Builder

Add Keychain and fill out valid values for Keychain Name and Keychain password.

Note: The keychain path is already present.


Apply the changes and save.

Use this link to fetch the member ID.

Post Build Actions

Post-build Actions

Under Post-build actions, select Set GitHub commit status (universal). Under the What: section, set Status result: to One of default messages and statuses.

After saving this, run the build

Triggering Jenkins GitHub Integration with Pushes

Now we are set with the GitHub Integration, Jenkins and Xcode along with Webhook.

Let’s try the push from GitHub and check the results in the webhook requests.

This article introduces Jenkins and explains its integration with GitHub and the Xcode plugins.

I will cover how to automatically create Jenkins jobs for pull requests or push commits in GitHub in my upcoming article.
