App: IconFly

To create a modern iPhone and iPad application, you need to provide icons in 14 different sizes. For a modern macOS application, you must provide icons in 10 different sizes. It can be rather tedious and time-consuming to create those files manually. But with IconFly, it takes a few seconds. Just import an image, and IconFly will take care of the rest so you can save your time for more important things. IconFly will create all sizes of app icons for you automatically. 

You can use the QuickIcon to create icons without preview or click Generate to see how your icons look in different sizes before exporting. You can easily replace an icon of any size if you have a specially designed image for that size.

Appiconset
IconFly supports Appiconset for:
• macOS 11
• iOS 14 with all-new iPhone 12 mini, iPhone 12, iPhone 12 Pro, iPhone 12 Pro Max, and iPad Pro

IconFly also supports Appiconset for the previous versions starting from macOS 10.8, iOS 7, and watchOS 1.

You can save the Appiconset generated by IconFly directly to the Assets Catalog inside your project, and it's ready to use with no additional steps. It contains all the necessary icon dimensions and a properly formatted JSON file.
