In the Play store it is possible to see what permissions are required and data is collected.
I don't know anything about the ways Apple developers interface with the app store to submit or update or index their apps ... is it through xcode ?
I wonder if there is some function in that toolchain that actually does what I am proposing ...
When permission is requested and you've forgotten to declare that your app asks for it, the permission will be immediately denied without prompting the user.
