SOLVED: Sort by Date but not Time

I think this has to be a simple fix, but I can't find it.

I want to sort information by date and by type. But the type sort isn't working. I move elements from type to type and they stay in the same order. I think this is because the time element of the date is keeping them in the same order because when I move the dates, they resort. But if they're all on the same date, they remain in the same order no matter what type I give them.

Is there a way to write a Sort array and tell it to ignore the time component of the timestamp the way you can omit time when formatting how a date is displayed?

MODEL

@Model
class Meal: Identifiable {
    let id = UUID()
    var title: String = ""
    var type: String = ""
    var date: Date = Date()

    init(title: String, type: String, date: Date) {
        self.title = title
        self.type = type
        self.date = date
    }
}

SORT

@Query(sort: [SortDescriptor(\Meal.date), SortDescriptor(\Meal.type)]) private var meals: [Meal]

DISPLAY

            HStack{
                    Label(meal.title, systemImage: "cup.and.saucer")
                Spacer()
                HStack{
                    Text(meal.date.formatted( Date.FormatStyle()
                        .weekday(.abbreviated)
                    ))
                    Text(meal.date.formatted( Date.FormatStyle()
                        .day(.twoDigits)
                        .month(.abbreviated)
                    ))
                }
            }

Do you need the Time? If no then add this to your project

extension Date {
    var startOfDay: Date {
        Calendar.current.startOfDay(for: self)
    }
}

then in your class do

var date = Date.now.startOfDay

However if you require the time not to be 00:00 (startOfDay) however would like to ignore it in sort then do it

@Query(sort: [SortDescriptor(\Meal.date.startOfDay), SortDescriptor(\Meal.type)]) private var meals: [Meal]

See if that will do the trick!

I don't need time at all. Thanks!
