iOS icon generator

Generate all the app icons needed with a single command.

Usage

./ios-icon-generator [IMAGE]

The source image should ideally be square and larger than 180x180, as the current largest icon size is 180x180 (for the iPhone 6 Plus).

The script will create an AppIcon.appiconset/ directory with all the necessary files and metadata needed by Xcode.

Filenames and sizes come from Apple's documentation.

Optimization

The icons will be losslessly compressed via ImageOptim (CLI), if available on your machine. The easiest way to install it is with:

npm install -g imageoptim-cli
