This Xcode Source Code Extension will generate a Swift initializer based on the lines you've selected. Handy if you made a struct public and now you have to provide the initializer implementation yourself.

Select the lines with the attributes that should be included in the initializer. See below; > is the start of the selection and < is the end of the selection.

struct MyStruct { > public var a: String public var b: Int< }

Run the extension's "Generate Swift Initializer". Voila! The code above is modified to:

struct MyStruct { public var a: String public var b: Int public init(a: String, b: Int) { self.a = a self.b = b } }

1. On OS X 10.11 El Capitan, run the following command and restart your Mac:

    sudo /usr/libexec/xpccachectl 

2. Open SwiftInitializerGenerator.xcodeproj

3. Enable target signing for both the Application and the Source Code Extension using your own developer ID

4. Product > Archive

5. Right click archive > Show in Finder

6. Right click archive > Show Package Contents

7. Drag Swift Initializer Generator.app to your Applications folder

8. Run Swift Initializer Generator.app and exit again.

9. Go to System Preferences -> Extensions -> Xcode Source Editor and enable the extension

10. The menu-item should now be available from Xcode's Editor menu.

It will only parse attributes defined like (open|public|fileprivate|private|internal) [weak] (var|let) NAME: TYPE.
