How to use EKEventEditViewController in SwiftUI
My finished solution to bridging this view controller for creating new events and editing existing ones to SwiftUI.
Published: Aug. 4, 2020 Sponsored See booksI have made another notable progress porting my EKEventKit Example app to SwiftUI with bridging the EKEventEditViewController. This ready-made controller will let you create new event and save it as well and also edit existing events that you can pass in.
This time I could draw inspiration from using EKCalendarChooser in SwiftUI from my previous post.
Complete code
Below is fully working code to use EKEventEditViewController in your SwiftUI.
import SwiftUI
import EventKitUI
struct EventEditView: UIViewControllerRepresentable {
func makeCoordinator() -> Coordinator {
return Coordinator(self)
}
@Environment(\.presentationMode) var presentationMode
let eventStore: EKEventStore
let event: EKEvent?
func makeUIViewController(context: UIViewControllerRepresentableContext<EventEditView>) -> EKEventEditViewController {
let eventEditViewController = EKEventEditViewController()
eventEditViewController.eventStore = eventStore
if let event = event {
eventEditViewController.event = event // when set to nil the controller would not display anything
}
eventEditViewController.editViewDelegate = context.coordinator
return eventEditViewController
}
func updateUIViewController(_ uiViewController: EKEventEditViewController, context: UIViewControllerRepresentableContext<EventEditView>) {
}
class Coordinator: NSObject, EKEventEditViewDelegate {
let parent: EventEditView
init(_ parent: EventEditView) {
self.parent = parent
}
func eventEditViewController(_ controller: EKEventEditViewController, didCompleteWith action: EKEventEditViewAction) {
parent.presentationMode.wrappedValue.dismiss()
if action != .canceled {
NotificationCenter.default.post(name: .eventsDidChange, object: nil) // custom notification to reload UI when events changed
}
}
}
}
Example usage
This can then be used with sheet modifier:
EventEditView(eventStore: self.eventsRepository.eventStore, event: self.selectedEvent)
You can pass nil as event to create new one using the EKEventEditViewController.

Uses: Xcode 12 & Swift 5.3
