I retrieve events from my calendar using Apple's EventKit

Now I have a list of my events with details. I'd like to choose a particular event and change my (and only my) attendance status (i.e from Maybe to Accept).

I can't see an obvious option for that. I can read:

• "EventKit cannot add participants to an event nor change participant information." EkParticipant
• "Attendees is read-only property" Attendees

Is there a way to do that?

I noticed the other approach with using EkEventEditViewController. I'd like to avoid that if possible.

PS. I saw these, but I thought they're kinda outdated:

• How to accept/decline EKEvent invitation?
• EKEvent accept event invtation
• Adding EKParticipants to an EKEvent in EventKit

I need to search an iOS device calendar for calendar events that contain a given text in the event notes. Apple describes this procedure for a date filter, where the filter conditions are defined in an NSPredicate instance - as in the following example (from https://developer.apple.com/documentation/eventkit/retrieving_events_and_reminders#overview) and many others I could find.

I have the following AppDelegate class, I want to determine when userPreferences.backgroundIsTransparent changes state, must call a function inside AppDelegate.

I took a look here: https://stackoverflow.com/a/58431723/8024296

But I'm failing to figure out how I can use it in my case.

How can I do?

AppDelegate:

I'm having the following problem can you tell me where I'm wrong?

I'm trying to build a calendar app for iOS using KVKCalendar but it's not originally build for Swift UI so I'm kind of struggling to achieve what I want to do.

My goal is changing calendar type (such as daily, weekly, monthly) by a segment controller, exactly like this example (which is already provided in git repository). sampleUI

So far, I managed to display daily style calendar view as default. But I don't know how I can change its calendar type from ContentView.swift

Does anyone know about this type of ViewController ↔ Swift UI thing?

My ContentView.swift is like this

I want to implement platform specific code for my Flutter app on iOS. I want to implement EventKit from native iOS. but now I am confused how to implement protocol delegate pattern in the app delegate when using Platform Channel in Flutter.

in native iOS, my code will be like this

• vyper Version (output of vyper --version): 0.2.8+commit.069936f
• OS: osx
• Python Version (output of python --version): Python 2.7.16
• Environment (output of pip freeze):

[Update: I submitted an official Apple Developer feedback request for an update to the EventKit API and documentation]

[Update: I contacted Apple Support and they said to read the docs...so I think Matt is correct, It is simply not available.]

According to Apple Docs, the EKReminder is a subclass of EKCalendarItem. It has the following (lot) of properties:

As a reminder:

• priority: Int - The reminder's priority.
• startDateComponents: DateComponents? - The start date of the task.
• dueDateComponents: DateComponents? - The date by which the reminder should be completed.
• isCompleted: Bool - A Boolean value determining whether or not the reminder is marked completed.
• completionDate: Date? The date on which the reminder was completed.

As a calendar item:

• title: String! -The title for the calendar item.
• location: String? - The location associated with the calendar item.
• creationDate: Date? - The date that this calendar item was created.
• lastModifiedDate: Date? - The date that the calendar item was last modified.
• timeZone: TimeZone? - The time zone for the calendar item.
• url: URL?
• hasNotes: Bool - A Boolean value that indicates whether the calendar item has notes.
• notes: String? - The notes associated with the calendar item.
• hasAttendees: Bool - A Boolean value that indicates whether the calendar item has attendees.
• attendees: [EKParticipant]? -The attendees associated with the calendar item, as an array of EKParticipant objects.

I can print any one of these items from reminders in my app.

However, if I create a reminder that is "assigned to a person", I cannot get that information. I know it must be stored somewhere.

If you "print" a reminder, you get something like this:

In Apple's EventKit each Calendar can have a user-definable color, which can also be accessed on the EKCalendar instance as EKCalendar.color. How can that color be accessed from a single event (not a calendar)? Is there any back-reference from an EKEvent instance to the EKCalendar the event belongs to?

As an example, I have a list of calendars and fetch events by start and end date. In the resulting array of events it seems any information answering a question "from which calendar a single event is" got lost.
