From the developer:
Iconomy helps you create icons for various target devices. You simply drag your high-resolution icon into the app, select your output device, and everything else is taken care of automatically. All necessary retina versions will be created. You can even batch-resize or tint your icons directly in the app, without altering the original.
You can directly export into an existing Asset Catalog file or drag your icons into Xcode.
