Using asset catalog "Folder with Namespace" in Swift

I want to access to a small number of Markdown text files. It looks like the asset catalog feature "Folder with Namespace" might do well, as I could store these small files in a folder that the asset catalog contains. How would I go about getting the string contents of a particular file if I know its name?
