According to apples documentation:

NSCalendarsUsageDescription (String - iOS) This key lets you describe the reason your app accesses the user’s calendars. When the system prompts the user to allow access, this string is displayed as part of the alert.

it then goes on to explain how to implement it:

Important: To protect user privacy, an iOS app linked on or after iOS 10.0, and which accesses the user’s calendars, must statically declare the intent to do so. Include the NSCalendarsUsageDescription key in your app’s Info.plist file and provide a purpose string for this key. If your app attempts to access the user’s calendars without a corresponding purpose string, your app exits.

Basically just insert this into you info.plist file

 NSCalendarsUsageDescription
purpose for using calendar
