How do I edit an Info.plist file? I want to edit three lines of file



Whenever I try to edit it this comes up



I already gave myself permission to Read &amp; Write (I'm 21muffinp)



The same thing still comes up, saying I do not have perimission.
You need read/write permissions to the containing folder as well as the plist itself for Xcode to modify the file in place.

A workaround for this if you are unable to change the permissions of the containing folder is to copy the file out, edit it, then copy it back over the top of the existing file. Alternatively, you can use a different property list editor such as the CLI ‘defaults’.
