Going back to dark ages

After coding in Java for over a decade, half of that with IntelliJ I am now trying to code Objective-C in Xcode. As with learning to use any new IDE this is not a fun exercise and I am constantly comparing Xcode to IntelliJ & so far there is only one winner. I can only find only a few built-in refactorings in Xcode. Does Xcode has anything like plugins? Is there a better tool for refactoring Objective-C?
