Xcode Plugin that Refactors Swift & Objective-C

Refactorator Xcode Plugin

Refactorator is an Xcode plugin for refactoring Swift & now Objective-C 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.

Stop Press: Refactorator no longer uses SourceKit directly, rather it accesses the SQLite database Xcode compiles using SourceKit. This makes it both faster as it no longer needs to re-index the sources of your project but also means all targets of a project are included in refactoring including code written in Objectve-C.

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 if need be.

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 coloured 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 data from 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. Invaluable in underdstanding the index database was DB Browser for SQLite and the SQLite Swift code was helped along by reference to the excellent SQLite.swift.
