Make an Xcode app icon on your Mac

Xcode keeps your app icon in the asset catalog, as an AppIcon set. Forrrge makes the icon from a description and exports a ready AppIcon set to drop in, or every PNG size.

What Xcode needs

Apple's guide to configuring your app icon splits it by platform:

iOS, iPadOS, watchOS and tvOS can generate every icon variation from a single 1024×1024 image. That's the default for new apps.
macOS needs an image for each size. This is where exporting every size at once saves the work of making and placing them one by one.
Layered icons for every platform and appearance are made in Apple's Icon Composer.

Export from Forrrge

Once you have an icon you like, Forrrge exports it three ways:

A ready AppIcon set to drop into Xcode.
A 1024 PNG to hand to Icon Composer, or to use as the single size Xcode generates from.
Every PNG size, when you want the files themselves.

You can also drag a render straight to Xcode, Figma, or Finder, and batch export from the gallery.

Making the icon

Describe it. Start with a mascot, metaphor, object, or mood. You can add a reference image too.
Pick a style. Sixteen render styles, from Glass and Clay to Flat, Pixel, and Watercolor, with lighting, palette, and texture to tune.
Compare. Renders stream in as they generate, and every one saves to the gallery with the recipe that made it.
Clean it up. Remove the background in one click, on your Mac, then export.

Already have an icon?

Forrrge makes icons; it isn't a resizer for artwork you already have. For iOS and iPadOS, Xcode can generate the sizes from one 1024×1024 image on its own (Single Size in the asset catalog's attributes).

What you need

Forrrge from the Mac App Store: $2.99 once, no subscription. The same purchase covers iPad, which exports a PNG through the share sheet; Xcode icon packs stay on the Mac for now.
An image-model API key from Google, OpenAI, or Hugging Face. One is enough to start, and renders bill to that provider. How the keys work.
