Sheet and modal UIKit and SwiftUI [duplicate] - ios

Question

I have been trying to use EKEventEditViewController with SwiftUI. I tried to follow some suggestions from dev forums as to how to go about adding it with the help of a UIViewControllerRepresentable wrapper with a Coordinator. I am adding the code below.
The EKEventEditViewController is presented correctly but the problem I'm facing is that only some of the fields are editable. I'm attaching a gif showing the interactions.
Has anyone faced this issue ?
Here is the code:
import Foundation
import SwiftUI
import EventKitUI
let eventStore = EKEventStore()
struct NewEventGenerator: UIViewControllerRepresentable {
typealias UIViewControllerType = EKEventEditViewController
#Binding var isShowing: Bool
var theEvent = EKEvent.init(eventStore: eventStore)
func makeUIViewController(context: UIViewControllerRepresentableContext<NewEventGenerator>) -> EKEventEditViewController {
let controller = EKEventEditViewController()
controller.event = theEvent
controller.eventStore = eventStore
controller.editViewDelegate = context.coordinator
return controller
}
func updateUIViewController(_ uiViewController: NewEventGenerator.UIViewControllerType, context: UIViewControllerRepresentableContext<NewEventGenerator>) {
uiViewController.view.backgroundColor = .red
}
func makeCoordinator() -> Coordinator {
return Coordinator(isShowing: $isShowing)
}
class Coordinator : NSObject, UINavigationControllerDelegate, EKEventEditViewDelegate {
#Binding var isVisible: Bool
init(isShowing: Binding<Bool>) {
_isVisible = isShowing
}
func eventEditViewController(_ controller: EKEventEditViewController, didCompleteWith action: EKEventEditViewAction) {
switch action {
case .canceled:
isVisible = false
case .saved:
do {
try controller.eventStore.save(controller.event!, span: .thisEvent, commit: true)
}
catch {
print("Event couldn't be created")
}
isVisible = false
case .deleted:
isVisible = false
#unknown default:
isVisible = false
}
}
}}

Works fine with Xcode 12 / iOS 14. Literally copy-pasted your code added requestAccess & descriptions in Info.plist.
Full tested module, for the case if something might be helpful.
import SwiftUI
import EventKitUI
let eventStore = EKEventStore()
struct NewEventGenerator: UIViewControllerRepresentable {
typealias UIViewControllerType = EKEventEditViewController
#Binding var isShowing: Bool
var theEvent: EKEvent
init(isShowing: Binding<Bool>) {
eventStore.requestAccess(to: .event) { allow, error in
print("Result: \(allow) or [\(error.debugDescription)]")
}
theEvent = EKEvent.init(eventStore: eventStore)
_isShowing = isShowing
}
func makeUIViewController(context: UIViewControllerRepresentableContext<NewEventGenerator>) -> EKEventEditViewController {
let controller = EKEventEditViewController()
controller.event = theEvent
controller.eventStore = eventStore
controller.editViewDelegate = context.coordinator
return controller
}
func updateUIViewController(_ uiViewController: NewEventGenerator.UIViewControllerType, context: UIViewControllerRepresentableContext<NewEventGenerator>) {
uiViewController.view.backgroundColor = .red
}
func makeCoordinator() -> Coordinator {
return Coordinator(isShowing: $isShowing)
}
class Coordinator : NSObject, UINavigationControllerDelegate, EKEventEditViewDelegate {
#Binding var isVisible: Bool
init(isShowing: Binding<Bool>) {
_isVisible = isShowing
}
func eventEditViewController(_ controller: EKEventEditViewController, didCompleteWith action: EKEventEditViewAction) {
switch action {
case .canceled:
isVisible = false
case .saved:
do {
try controller.eventStore.save(controller.event!, span: .thisEvent, commit: true)
}
catch {
print("Event couldn't be created")
}
isVisible = false
case .deleted:
isVisible = false
#unknown default:
isVisible = false
}
}
}}
struct TestEventKitViewInSheet: View { // just created in ContentView body
#State private var showIt = false
var body: some View {
Button("Events") { showIt = true }
.sheet(isPresented: $showIt) {
NewEventGenerator(isShowing: $showIt)
}
}
}
