objc2swift

objc2swift is an experimental project aiming to create an Objective-C -> Swift converter (or at least something that would help a human being convert codes by hand).

The software is based on ANTLR the magnificent parser generator.

Quick Start

Build the project, run the jar with an input Obj-C source file.

$ gradle build
$ java -jar build/libs/objc2swift-1.0.jar sample/sample.h

With the input Obj-C code:

@interface A : NSObject

@end

you'll get the Swift code as below:

class A : NSObject {

}

Features

converts @interface Hoge to class Hoge {}
... that's all for now!

Developer's Guide

1. Project Setup

Import Project from gradle build file:

Create new Run Configuration as below:

2. Project Structure

coming soon...

3. Printing the Parse Tree

With the -t option, the parse tree of the input source will be printed. You can use this to find the name and the containing text for each node.

$ java -jar build/libs/objc2swift-1.0.jar sample/sample.h -t

input:

@interface A : NSObject

@end

output:

/* Hello Swift, Goodbye Obj-C.
 * converted by 'objc2swift' https://github.com/yahoojapan/objc2swift
 *
 * source: sample/sample.h
 * source-tree:
 *  translation_unit: '@interface' - '@end'
 *    external_declaration: '@interface' - '@end'
 *      class_interface: '@interface' - '@end'
 *        class_name: 'A'
 *        superclass_name: 'NSObject'
 */

class A : NSObject {

}
