What is?

Scripts to automatically generate iOS icons and launch images in the correct sizes. Also contains optimal asset catalogs with reused images for identical sizes.

Tested with Xcode 9 and iOS 6-11.

No dependencies.

Usage

Default-Input.png and Icon-Input.png contain the initial graphics for the launch image and icons respectively.

From Terminal run:

./CreateiOSLaunchImages.sh

and

./CreateiOSIcons.sh

and

./CreateiOSToolbarNavigationIcons.sh

to create all necessary size variants.

Optional

Remove variants that are not needed (e.g. iPad Portrait) from the catalogs to optimize app size.
