defaultCalendarForNewEvents failed

Question

When I try to call [newEventStore defaultCalendarForNewEvents], it returns an error message says:

[707:907] defaultCalendarForNewEvents failed: Error Domain         


        

Answer 1

Swift form

(based on @yunas answer)

_estore = EKEventStore()
_estore.reset()

_estore.requestAccessToEntityType(EKEntityTypeEvent) { (granted, error) in
    if granted {
        println("allowed")
        /* ... */
    } else {
        println("not allowed")
    }           
}

It will open "Access" pop-up
