CI/CD with Xcode Cloud in iOS Swift - UI Render Trace

Component - CI/CD with Xcode Cloud

This UI component shows the main screen of Xcode Cloud's CI/CD pipeline setup. It helps developers automate building, testing, and delivering iOS apps. The screen displays the pipeline status, build logs, and buttons to start or stop builds.
