I regularly need to generate the Assets.xcassets folder which contains an AppIcon.appiconset folder with a Contents.json and multiple (png) image files. Those files are App icons for iOS.

I'm currently using the Asset Catalog Creator, which has the major downside that I need to run it on iOS. I'm looking for something that runs on .

I imagine a command line utility that takes a PNG image as input and produces the output. The background should either be configurable or white. If the input image does not have a 1:1 aspect ratio, the image is centered.
