Workflows in Xcode Cloud define the steps for building, testing, and distributing your app. For your convenience, you can establish more than one workflow for different branches or stages of your development process.
- Create a New Workflow: In the Xcode Cloud settings, click “Create Workflow.”
- Select Trigger: Choose when the workflow should run. Common triggers include:
- Push to Branch: Runs the workflow whenever code is pushed to a specific branch.
- Pull Request: In the event of an opened and updated pull request, you can run the workflow.
- Configure Actions: Define the actions that will be performed. Typical actions include:
- Build: Compile your app.
- Test: Run unit tests, UI tests, and other automated tests.
- Analyze: Perform static code analysis to identify potential issues.
- Archive: Create an archive of your app for distribution.
- Distribute: Distribute your app to testers or submit it to the App Store.
-
Define Build Settings
In this step you are required to highlight the build settings for your workflows, which includes the scheme to build, the configuration (Debug/Release), and any custom build arguments. Being a developer, you must select the correct signing and provisioning profiles.
-
Configure Test Settings
Set up your test targets and clearly identify the devices and configurations on which you wish to run your tests. Xcode Cloud will then do its job by letting you test on a wide range of simulated devices and configurations, which is imperative for comprehensive test coverage.
-
Set Up Distribution
Configure the distribution settings for your app. You can distribute the app to testers via TestFlight or submit it directly to the App Store. But before everything else, make sure that the necessary credentials and profiles are in place and set up for distribution.
Monitoring and Managing Workflows
Once set up the workflows, Xcode Cloud will automatically trigger them based on your chosen configuration. You can monitor the status and results of your workflows in Xcode or the Xcode Cloud web dashboard.
Viewing Workflow Results
- Build Logs: This includes elaborate logs of the entire build process inclusive of errors or warnings.
- Test Results: Results of your automated tests, including pass/fail status and detailed logs.
- Distribution Status: Status of your app distribution, including any issues encountered during submission.
Managing Workflow Configurations
- Editing Workflows: Update your workflows to adjust triggers, actions, and settings as your project evolves.
- Viewing History: Access the history of workflow runs to review past builds, tests, and distributions.
Best Practices for Using Xcode Cloud
- Modularize Your Workflows: Create separate workflows for different stages (e.g., build, test, deploy) to simplify management and troubleshooting.
- Optimize Build Times: Use caching and parallelization to speed up build times.
- Comprehensive Testing: Ensure you have thorough test coverage to catch issues early in the development process.
- Monitor Resource Usage: Keep an eye on your Xcode Cloud usage to avoid unexpected costs.
