问题
I give up, I can't figure it out. I'm new to mac, and this is driving me insane.
The steps outlined here are not sufficient: https://developer.apple.com/library/mac/recipes/xcode_help-image_catalog-1.0/chapters/AddingIconSets2.html
The result: the blocky "exec" icon.
What else do I need to do? The .xcassets files I created have been added to the "Copy Bundle Resources" build phase. However, the executable isn't any larger.
I also created an .icns file, and I was never able to get that to work either. I think these are deprecated?
