This is probably the application that many programmers have been waiting for, CodeSwitch is the first Objective-C to Swift code converter for Mac OS X.
CodeSwitch will convert all of your Objective-C code into Swift code instantly. Simply copy-and-paste any Objective-C code into this program, and it will translate it to Swift in milliseconds.
So those legacy programs won't need a complete rewrite!
The latest post on the Swift blog highlights a new feature in Xcode 7.1, the ability to embed file, image, and color literals into your playground’s code.
For instance, there’s no need to type “myImage.jpg” in the editor – just drag your image from the Finder and the actual image will appear in-line with your code.
Useful if you tend to name images, image1, image 2 etc ;-)
