How can you create an iCloud Calender for an iOS app to use with swift? -

i've seen many people search user's calendars , grab first 1 that's writable , start throwing events on there. don't practice; prefer respect users little more.

so how can make own calendar app use events creates?

i came following function, assuming app allowed access users calendars:

let eventstore = ekeventstore()  func checkcalendar() -> ekcalendar {     var retcal: ekcalendar?      let calendars = eventstore.calendarsforentitytype(ekentitytypeevent) as! [ekcalendar] // grab every calendar user has     var exists: bool = false     calendar in calendars { // search these calendars         if calendar.title == "any string" {             exists = true             retcal = calendar         }     }      var err : nserror?     if !exists {         let newcalendar = ekcalendar(forentitytype:ekentitytypeevent, eventstore:eventstore)         newcalendar.title="any string"         newcalendar.source = eventstore.defaultcalendarfornewevents.source         eventstore.savecalendar(newcalendar, commit:true, error:&err)         retcal = newcalendar     }      return retcal!  } 

this function looks calendar name of "any string". of course, can like. if doesn't exist, create it. returns calendar, can assign calendar variable , work please.
