Icon Set Creator lets you quickly create icon assets for your apps: Just drag your high-resolution artwork (preferably, a PNG file at 1024x1024) into the app's window, chose the target platform, select a directory for exporting the results, and you're set. The currently supported formats are iOS, macOS, watchOS, and iMessage Apps.
Ideally, you would want to have your designer fine-tune each icon size by hand, for best visual results in terms of detail, pixel alignment, etc.
But if you just want to quickly fill all the "buckets" in the AppIcon entry of your asset catalog, this simple tool can help you.
What's new in version 1.1.10: (September 2018)
- Added support for iMessage sticker apps.
Fixed some unreadable labels in the new macOS Mojave's "dark mode".

An app that should have been inside Xcode
Thank you, thank you, thank you! I first made my own icon sets manually using Preview or another image editor. Tedious! Then I created a script to do it for me in Apple’s Automator. That was time consuming too and clunky, but saved me some time later. This program is better and easier to use than my script. And I noticed that it generates a json file too. Cool! It would be nice if this App could generate some custom sizes too (for web pages), but that’s ok. It is a real time saver for building an app in Xcode!
I use it all the time
Thanks for keeping the app up to date, Nicolas. I use it constantly. Very well done. I wish it defaulted to iOS icons instead of macOS icons, or at least remembered my last-used setting, but otherwise, this app is perfect.
Add this to your toolset
I use this app for every relese. I'm a fan of its simplicity but it's lacking a few small things…
Recently tried it with a Message extension and it doesn't seem to have a way to handle the non-square icons correctly yet. It also doesn't attempt to name duplicate folders if you need saving icon sets to the same folder. I'd love to contact you directly dev friend but you haven't listed an email anywhere via your "App Support" link ;)
Coffee bought instantly.
With Family Sharing set up, up to six family members can use this app.
