Good for simple tasks, lacking in features to be great

The app works “ok” for the most part but it could be so much more there’s no way I can give it a good rating in its current shape. For one, it should be relatively easy given the amount of information it has already to generate XCAssets and properly package up each asset into its own asset container. Would save ton of time from having to manually drag all those individual files into their resolution container in Xcode and having to manually name the image assets.

Two, the application icon export is missing Apple Watch support and some other resolutions. For example there were no 20x20 app icon; which is a bummer. The app “Asset Catalog Creator” is should be reviewed by this app developer to get some inspiration as to what it can achieve.

Three, the app should have some kind of indicator whether there are newer assets that have not been exported yet, maybe add some badge on the export button or something.

Really nice!

I really love the fact that I can ask for the high-res asset(s) and get them converted automatically into all the supported formats instantly. However, if there is a downside, it's performance, if you have 20+ asset into a prepo file, the program get super slow to scroll (which makes finding assets super cumbersome). I look forward to the next iteration of the program, hopefully, there will be performance improvements and more thought put into large projects.
