How to setup xcode11 entitlement to read/write an plist from excel groupcontainer

I need to edit a plist file from MS Excel on MacOS

Is the plist inside Excel ?

This plist is inside the group container.

group container of who ?

Hi Claude,

nope, the plist is inside the group container used by Excel.

I can open the file if I use the open panel in code, because I have that entitlement set ( file access typ : userselected file access ).

Does this answer (no) to your question ?

I guess this is about something different but a link in there can be usable. I will check this out. Thank you.

My main questions is how I do add an file reference, in this case the plist, in the entitlement.

I did found out I did have to create a

'com.apple.security.temporary-exception.files.home-relative-path.read-write'

key with the relative path in the projects entitlement file inside the project and now it works so far.
