How can I save a Date in AppStorage within Swift?

Using Swift

I ended up using a set/get:

    @AppStorage("storedStartTime") var storedStartTime = Date.now.timeIntervalSinceReferenceDate
    var startTime: Date {
        set {storedStartTime = newValue.timeIntervalSinceReferenceDate}
        get {return Date(timeIntervalSinceReferenceDate: storedStartTime)}
    }
