Our app provides a calendar that integrates with the default calendar app. Specifically, we use iOS EventKit to perform CRUD operations on calendar data.
Recently, we have received reports from users that all of their events have disappeared. However, after reviewing our implementation and logs, we have not been able to identify the cause. Some users have also reported that all data in their default calendar app has disappeared as well.
Does anyone have any idea what might be causing this?
To delete an event within our app, users must press the delete button and then confirm the deletion in a dialog. Additionally, it is not possible to delete more than two events at once.
We've seen many people in the community discussing a bug where calendar events disappear after updating to iOS 18. If you have any information about when or why this happens, we'd appreciate it if you could share your insights.
