Are game applications allowed to have permission to read and write the calendar? Is this permission limited to certain types of applications? Are there any specific requirements for developers when using calendar read/write permissions? If so, what steps should developers follow to utilize this permission?
Calendar permission issue
Thank you for your post. Even thought is in the App Store API but your questions is about the calendar permission? Could you please provide more details about your requirements? Are you referring to the iOS or macOS version of the game app? I recommend starting with EventKit, which provides access to add events to the calendar if that is your objective.

The more information you provide, the more developers in the forums will be able to offer their opinions and insights on the most suitable frameworks and APIs for your game. Additionally, I recommend searching the forums for calendar access in the platform you are considering.
