Access IOS extrafilesystem [Library files]

I need to get the directories and files inside the library folder in ios.I have done this in android with external root directory with the help of ionic native file plugin. Anybody has solution for this?
Thanks in advance

Start by comparing the requested iOS library-folder access with the Android external-root approach described in the issue. Determine whether the plugin can expose those iOS directories and files, and define the supported behavior before changing anything; done means the capability and its platform limitations are documented or implemented.
