# Generate app icons and xcassets file from a single image
# Ben Clayton, Calvium Ltd. 
# --------------------------------------------------------
# To use this, place script in `appname` folder inside your project (i.e. the folder that Xcode generates for you containing your source code, it's named after whatever you called the app). 
# Create folder there called `RawImages`. 
# Source icon should 1024x1024 and be called appIcon.png. If the icon changes, you can just run this again to regenerate everything.
# This script assumes that you have the default setup of an Images.xcassets file containing the AppIcon.appiconset.
