创建没有警报的 EKEvent

Question

I'm creating an EKEvent attached to a custom calendar. Whenever I create the EKEvent an alarm is set for the time of the event, however, I would like this event to not have an alarm on creation.

I've tried setting the event's alarms property to...

event.alarms = nil

as well as...

event.alarms = []

I've also tried setting the alarm to a distant future data, but this just adds another alarm to the event...

event.alarms = [Date.distantFuture]

I've done all this before saving the event, but it has given me no results, the alarm fires no matter what I do. :(

Here is the code I'm using to create the calendar:

let calendar = EKCalendar(for: .event, eventStore: store)
var source = store.sources.filter{ $0.sourceType == .calDAV && $0.title == "iCloud" }.first
if source == nil {
    source = store.sources.filter{ $0.sourceType == .local }.first
}
calendar!.title = "Some Title"
calendar!.cgColor = ColorKey.orange.color().cgColor
calendar!.source = source!

do {
    try store.saveCalendar(calendar!, commit: true)
} catch {
    //error handling here...
}

And this is the code that I'm using to create the event:

let event = EKEvent(eventStore: store)
event.title = "Some title"
event.notes = "Some notes"
event.startDate = dateToFire
event.endDate = dateToFire.addingTimeInterval(TimeInSeconds.hour.rawValue)
event.isAllDay = false
event.calendar = calendar
do {
    try store.save(event, span: EKSpan.futureEvents)
} catch {
    //error handling here...
}

Is this a bug on the OS or am I missing something? Thanks!

There are default alert settings in Apple's Calendar app. Launch Calendar, then go to Preferences, Alerts. There are three settings there (Events, All Day Events, Birthdays). Set them to "None." (I'm using macOS 10.14, Calendar 11.0.)
