pod gen allows you to keep your Podfile and podspecs as the single source of truth for pods under development. By generating throw-away workspaces capable of building, running, and testing a pod, you can focus on library development without worrying about other code or managing an Xcode project. pod gen works particularly well for monorepo projects, since it is capable of using your existing settings when generating the workspace, making each gen'ed project truly a small slice of the larger application.
