Refactorator is an Xcode plugin for refactoring Swift code. It will rename public or internal vars, functions, enums etc. For private and local entities use Xcode's existing "Edit All in Scope" functionality. It uses SourceKit, an XPC service distributed with Xcode to parse your project's Swift sources to find symbol references.
Where a symbol is defined in a framework Refactorator will parses across targets to the framework if you start in the referring module. Similarly for overrides, start by selecting the overriding method.
To use, download the source for this project and build to install the plugin then restart Xcode. Not used a Plugin before? Use Alcatraz Package Manager to install it. Select a symbol in a Swift source and use "Right-click/Refactor/Swift !" to list places in the target that declare or refer to that symbol. Enter a new value for the identifier in the bottom textfield and press the "Preview" button to view the changes that would be made. Press the "Save" button to save these changes to disk. Use the "Undo" button to revert the changes.
As a by-product of the analysis performed for refactoring, if you have Graphviz installed, you can view an approximate visualisation of the classes in your project and their interrelationships using the "Edit/Refactor/Visualise !" menu item. Initialiser calls are colored green, ivar references blue, and method calls red:
Refactorator was originally suggested as being feasible by @Daniel1of1 shortly after Swift came out building on the work by @jpsim on SourceKitten. The last piece of the puzzle was the Open Sourcing of the SourceKit API by Apple as a part of Swift. Source files are parsed using the same XPC calls that Xcode uses when it indexes a project and implemented in a daemon process so as not to affect the stability of Xcode.
