This tiny script can save you a great deal of time creating icons for your iOS app. Just run the script in your console and it will automatically create icons in all resolutions that you can use in your Xcode iOS project.
You can place the script into your /usr/bin to run it like make_icons.swift; otherwise specify full/relative path to script e.g. ./make_icons.swift. You can also freely remove .swift extension.
Usage:
make_icons.swift <icon_name(s)>
where icon_name is relative or full path to the file
This script looks for @3x.png files in the directory you're running it from, and makes @2x and @1x versions automatically.
You can place the script into your /usr/bin to run it like scale_artworks.swift; otherwise specify full/relative path to script e.g. ./scale_artworks.swift. You can also freely remove .swift extension.
Usage:
In terminal, cd to folder with artworks and run scale_artworks.swift or copy the script to the folder and run ./scale_artworks.swift
