High Resolution Icon Composer

Question

Icon composer was removed in Xcode 4.4 and Apple now wants us to use

iconutil -c icns

to generate high resolution icons for Mac apps. In general, I design a single icon at 1024 pixels.

Whereas I could drag and drop that image into every box in the Icon Composer previously, I will now have to manually create icons of each size.

Does anyone know of any third party app or command line tools which will generate all of the icons and icns from a 1024 px file?

Answer 1

There's about a million $0.99 apps on the app store, but you can also use the apple command line tool sips

I wrote up a small script ages ago that might give you a start.

Answer 2

You can actually still download Icon Composer.

Go to https://developer.apple.com/downloads/index.action and search for "Graphics Tools", you'll see several Graphics Tools for Xcode disk images. Grab the latest one, and you should find Icon Composer inside of it.
