Indeed, significant progress has been made in recent years to break open the developer workflow, from alternative IDEs like AppCode to build tools like CocoaPods, xctool and nomad.

Xcode has had a plugin architecture going back to when Interface Builder was its own separate app. However, this system was relatively obscure, undocumented, and not widely used by third parties. Despite this, developers like Delisa Mason and Marin Usalj have done incredible work creating a stable and vibrant ecosystem of third-party Xcode extensions.
