How to add an event in the device calendar using swift?
SwiftEkeventEkeventstoreSwift Problem Overview
I would be interested in knowing how to add a calendar event in the device, but using swift. I know there are some examples made in Objective-C, but at the moment nothing in swift. Many thanks.

Solution 1 - Swift
Note: If your app is crashing with This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSCalendarsUsageDescription key with a string value explaining to the user how the app uses this data., you'll need to add NSCalendarsUsageDescription to your info.plist. Can follow the example here.
Swift 5.0 Version
import Foundation
import EventKit
let eventStore : EKEventStore = EKEventStore()
// 'EKEntityTypeReminder' or 'EKEntityTypeEvent'
eventStore.requestAccess(to: .event) { (granted, error) in
if (granted) && (error == nil) {
print("granted \(granted)")
print("error \(error)")
let event:EKEvent = EKEvent(eventStore: eventStore)
event.title = "Test Title"
event.startDate = Date()
event.endDate = Date()
event.notes = "This is a note"
event.calendar = eventStore.defaultCalendarForNewEvents
do {
try eventStore.save(event, span: .thisEvent)
} catch let error as NSError {
print("failed to save event with error : \(error)")
}
print("Saved Event")
}
else{
print("failed to save event with error : \(error) or access not granted")
}
}

Solution 2 - Swift
Swift 3.0 compatible:
func addEventToCalendar(title: String, description: String?, startDate: Date, endDate: Date, completion: ((_ success: Bool, _ error: NSError?) -> Void)? = nil) {
let eventStore = EKEventStore()
eventStore.requestAccess(to: .event, completion: { (granted, error) in
if (granted) && (error == nil) {
let event = EKEvent(eventStore: eventStore)
event.title = title
event.startDate = startDate
event.endDate = endDate
event.notes = description
event.calendar = eventStore.defaultCalendarForNewEvents
do {
try eventStore.save(event, span: .thisEvent)
} catch let e as NSError {
completion?(false, e)
return
}
completion?(true, nil)
} else {
completion?(false, error as NSError?)
}
})
}
And also import EventKit
So you can easily call this method from everywhere:
addEventToCalendar(title: "Girlfriend birthday", description: "Remember or die!", startDate: NSDate(), endDate: NSDate())
If you prefer, you can put this method inside an utiliy class and define it as 'static'.

You need to add "Privacy - Calendars Usage Description" to info.plist. Following code works with latest version of xcode and swift 3.
import EventKit
class EventHelper
{
let appleEventStore = EKEventStore()
var calendars: [EKCalendar]?
func generateEvent() {
let status = EKEventStore.authorizationStatus(for: EKEntityType.event)
switch (status)
{
case EKAuthorizationStatus.notDetermined:
// This happens on first-run
requestAccessToCalendar()
case EKAuthorizationStatus.authorized:
// User has access
print("User has access to calendar")
self.addAppleEvents()
case EKAuthorizationStatus.restricted, EKAuthorizationStatus.denied:
// We need to help them give us permission
noPermission()
}
}
func noPermission()
{
print("User has to change settings...goto settings to view access")
}
func requestAccessToCalendar() {
appleEventStore.requestAccess(to: .event, completion: { (granted, error) in
if (granted) && (error == nil) {
DispatchQueue.main.async {
print("User has access to calendar")
self.addAppleEvents()
}
} else {
DispatchQueue.main.async{
self.noPermission()
}
}
})
}
func addAppleEvents()
{
let event:EKEvent = EKEvent(eventStore: appleEventStore)
event.title = "Test Event"
event.startDate = NSDate() as Date
event.endDate = NSDate() as Date
event.notes = "This is a note"
event.calendar = appleEventStore.defaultCalendarForNewEvents
do {
try appleEventStore.save(event, span: .thisEvent)
print("events added with dates:")
} catch let e as NSError {
print(e.description)
return
}
print("Saved Event")
}
}
Solution 4 - Swift
I was able to adjust this and eliminate the compiler error mentioned in the comments to the answers above (and a few others), as follows:
var eventStore : EKEventStore = EKEventStore()
// 'EKEntityTypeReminder' or 'EKEntityTypeEvent'
eventStore.requestAccessToEntityType(EKEntityType.Event, completion: {
(granted, error) in
if (granted) && (error == nil) {
print("granted \(granted)")
print("error \(error)")
var event:EKEvent = EKEvent(eventStore: eventStore)
event.title = "Test Title"
event.startDate = NSDate()
event.endDate = NSDate()
event.notes = "This is a note"
event.calendar = eventStore.defaultCalendarForNewEvents
eventStore.saveEvent(event, span: EKSpan.ThisEvent, error: nil)
print("Saved Event")
}
})
However, I still get the following error at the bottom regarding "EKSpan.ThisEvent" : Incorrect argument label in call (have ':span:error:', expected ':span:commit:').
I tried changing "error" to "commit," but it gave me a compiler error saying it expected a Bool instead of nil. It seems like a problem having to do with updates in swift syntax.
Edit: I ended up following this tutorial and was able to get it to work.
-
First, ask permission to access the calendar and (if that permission is granted) call a function to add the event.
var savedEventId : String = "" func requestAccessPermission() { let eventStore = EKEventStore() let startDate = NSDate() let endDate = startDate.dateByAddingTimeInterval(60 * 60) // Ends one hour later if (EKEventStore.authorizationStatusForEntityType(.Event) != EKAuthorizationStatus.Authorized) { eventStore.requestAccessToEntityType(.Event, completion: { granted, error in self.createEvent(eventStore, title: "Test Title", startDate: startDate, endDate: endDate) }) } else { createEvent(eventStore, title: "Test Title", startDate: startDate, endDate: endDate) } } -
The function that is called in the above code snippet to add the event:
func createEvent(eventStore: EKEventStore, title: String, startDate: NSDate, endDate: NSDate) { let event = EKEvent(eventStore: eventStore) event.title = title event.startDate = startDate event.endDate = endDate event.calendar = eventStore.defaultCalendarForNewEvents do { try eventStore.saveEvent(event, span: .ThisEvent) savedEventId = event.eventIdentifier } catch { print("Error Saving") } }

This was really slow on iOS 11.2 Xcode 9.2, so I modified Luca Davanzo's answer to use queues (works a lot faster):
func addEventToCalendar(title: String, description: String?, startDate: Date, endDate: Date, completion: ((_ success: Bool, _ error: NSError?) -> Void)? = nil) {
DispatchQueue.global(qos: .background).async { () -> Void in
let eventStore = EKEventStore()
eventStore.requestAccess(to: .event, completion: { (granted, error) in
if (granted) && (error == nil) {
let event = EKEvent(eventStore: eventStore)
event.title = title
event.startDate = startDate
event.endDate = endDate
event.notes = description
event.calendar = eventStore.defaultCalendarForNewEvents
do {
try eventStore.save(event, span: .thisEvent)
} catch let e as NSError {
completion?(false, e)
return
}
completion?(true, nil)
} else {
completion?(false, error as NSError?)
}
})
}
}
Solution 6 - Swift
same with location and alert
func addEventToCalendar(title: String, description: String?, startDate: Date, endDate: Date, location: String?, completion: ((_ success: Bool, _ error: NSError?) -> Void)? = nil) {
DispatchQueue.global(qos: .background).async { () -> Void in
let eventStore = EKEventStore()
eventStore.requestAccess(to: .event, completion: { (granted, error) in
if (granted) && (error == nil) {
let alarm = EKAlarm(relativeOffset: -3600.0)
let event = EKEvent(eventStore: eventStore)
event.title = title
event.startDate = startDate
event.endDate = endDate
event.notes = description
event.alarms = [alarm]
event.location = location
event.calendar = eventStore.defaultCalendarForNewEvents
do {
try eventStore.save(event, span: .thisEvent)
} catch let e as NSError {
completion?(false, e)
print ("\(#file) - \(#function) error: \(e.localizedDescription)")
return
}
completion?(true, nil)
} else {
completion?(false, error as NSError?)
print ("\(#file) - \(#function) error: \(error)")
}
})
}
}
