Have you gotten sick of creating the different iOS icon sized images in Photoshop or some other image editing application. Use this command line utility to create all of your icon assests.
npm i -g jimp-appicon
appicon -s MyAppIcon.png
If you do not specify a source, Appicon will will default to a file named 'Appicon.png' in the same directory this command is run. Appicon will save a directory called 'Icons' into the directory where this command is run.
Once you are done, simply copy the 'Appicon.appiconset' directory into the 'Assets.xcassets' directory in your iOS xcode project.
