Should we use absolute or calendar Date when scheduling background tasks? I would guess it doesn't matter how we construct Date but I wanted to double check since WWDC videos show both ways. I've experienced some instances where background tasks ran much later than expected, and while this is not surprising since iOS has many factors to consider when they allot background execution time, the times of execution seemed to line up with the hours change between Absolute and Calendar time. Or And I understand there is no guarantee that the system will run the background task exactly or even near the date requested. Thanks!

I want to get the attendees list of the calendar's event, and I dont know how to do it in Swift 3. I also want to get the email address of any event's attendee to contact them through my app. Does anyone can help me?Thanks.

OS: macOS Ventura App: Apple Calendar With the most recent Ventura version (and Apple Calendar) we are experiencing an issue with events that are initially added to the user's calendar (containing a predefined UID) and since then updated with the same UID. On the second event add/update, the event is not updated. Once the initial event has been added to Apple Calendar, we exported the calendar feed and noticed that the specific event had gotten an additional UID applied to the .ics file which we suspect is the cause of the issue. Steps: Download this .ics file and add it to Apple Calendar https://phpphp.dk/apple1.ics This .ics file contains an initial headline. The SEQUENCE field is set to 0 and the UID is predefined to hellouid. Download this .ics file and add it to Apple Calendar: https://phpphp.dk/apple2.ics This .ics file contains a different headline. The SEQUENCE field is set to 1 and the UID is set to hellouid. Expected behavior: The event

Hi All, I want to build a web application to automatically track calendar invitation status. After searching the forum I already figured out that there is no official apple api to access the calendar data of the user (without asking the user to enter his apple credentials). Luckily there is even a public accessible http endpoint to get the needed information: https://www.icloud.com/calendar/eventreply/?t=&p=p31&cc=DE This link is included in the email being sent out to the invited people. Navigating to the link shows the invitation status of all people invited to this event. Exactly what I need. Is it okay to use this endpoint for my purpose? Thanks in advance. Best, Jan

I created a function to add my course events to the calendar app using EventKit. After learning the swift concurrency, I want to update my code to make the progress much faster, namely using the detached task or TaskGroup to add these events. Synchronize code without detached task or task group: func export_test() { Task.detached { for i in 0...15 { print(Task (i): Start) let courseEvent = EKEvent(eventStore: eventStore) courseEvent.title = TEST courseEvent.location = TEST LOC courseEvent.startDate = .now courseEvent.endDate = .now.addingTimeInterval(3600) courseEvent.calendar = eventStore.defaultCalendarForNewEvents courseEvent.addRecurrenceRule(EKRecurrenceRule(recurrenceWith: .daily, interval: 1, end: nil)) do { try eventStore.save(courseEvent, span: .futureEvents) } catch { print(error.localizedDescription) } print(Task (i): Finished) } } } Doing the same thing using the TaskGroup : func export_test() { Task.detached { await withTaskGroup(of: Void.self) { group in for i in 0...15 { group.addTask

Basically I need a view with a calendar that will show data attributes from the item. I've tried two different approaches both have their listed problems. There must be a better way to do something like this. Surely it's not ideal to create a new item every time a date is opened or constantly check if something is there, but I don't know any other way. Actual View: import SwiftUI import CoreData struct ContentView: View { @Environment(.managedObjectContext) var managedObjContext @Environment(.calendar) var calenda @Environment(.dismiss) var dismiss @FetchRequest(sortDescriptors: [], predicate: NSPredicate(format: timestamp == %@, Date.now as CVarArg)) var items: FetchedResults @State private var date = Date.now var body: some View { NavigationView{ VStack{ DatePicker(Calendar, selection: $date, in: Date.now...,displayedComponents: [.date]) .datePickerStyle(.graphical) .onAppear(perform: { if (items.isEmpty){ PersistenceController().addItem(date: date, context: managedObjContext) } }
