Generated an assets.xcassets catalog that loads colors when plugin is applied to a target.
Note: This repo was created because I struggled to let colors be recognised. The problem was I added every individual
assets.xcassets/colorName.colorset/Content.jsonfile to the outputFiles of the build command. This causes duplicated files. Just adding the folder makes SPM load the a asset catalog correctly.
Take a look at the plugin GenerateColorAssets to find out how to do this if you struggle with the same.
This is visible if you build the target Foo and go to the build log.
