I am new to ios development. I am planning to use public database of cloudkit to store user's data.
I want to set security roles such that only creator of the record can access it. No other user (even authenticated) can access (not read/write) the record. Suppose, I deploy the application and users are using it and creating records.
Now In future, while giving update to this application, if I want to change the security roles, and give authenticated users, the permission to read the records created by other users.
Is this possible? and If Yes then the records which are created earlier (before the updated version ) can now be accessed (read )by authenticated users?
Thanks in advance,
Krishna
