ios – Populating a SwiftUI Picker with Calendars

I’m attempting to populate a SwiftIO picker with a listing of calendars.

So far as I can inform, the method ought to be one thing like this:

• Declare an array of calendars:
• Populate the array within the view’s onAppear methodology
• Populate the picker from the array.

I can’t get something to work with out some basic error. My code goes one thing like this:

Create the variable on the prime degree:

let eventStore : EKEventStore = EKEventStore()
let sources = eventStore.sources

var calendars: [EKCalendar] = []

Within the .onAppear() methodology populate the variable:

for supply in sources {
    calendars = calendars + supply.calendars(for: .occasion).sorted{ $0.title < $1.title }
}

Populate the picker:

struct ContentView: View {
    @Binding var calendar: EKCalendar!
    
    var physique: some View {
        VStack {
            Picker("Choose a calendar", choice: $calendar) {
                
//              ForEach(calendars) { calendar in
//                  Textual content("hahaha")
//                  Textual content(calendar.title)
//              }
            }
            .pickerStyle(.menu)
        }
    }
}

The commented out code above doesn’t work. How can I populate the picker?
