Build Kotlin default initialisers from Swift extension with default generics

[shial4]

I have a use case where I'm using the extension of a type supplying default types for generics
https://github.com/shial4/SwiftUIComponents/blob/main/Sources/SwiftUIComponents/Components/Calendar/CalendarView.swift#L129

extension CalendarView where Day == DefaultDayView, Header == DefaultCalendarHeaderView, Weekday == DefaultWeekdaysHeaderView {
    /// Initializes a calendar view with default configurations.
    ///
    /// - Parameters:
    ///   - date: A binding to the selected date.
    ///   - selection: A binding to the selected date range.
    ///   - calendar: The calendar to use for the view.
    ///   - type: The type of calendar view to display.
    ///   - colorSet: The color set to use for the calendar view.
    ///   - contentColorIndicator: A closure that returns the content color for a specific date.
    public init(date: Binding<Date>,
                selection: Binding<ClosedRange<Date>?> = .constant(nil),
                calendar: Calendar = Calendar(identifier: .gregorian),
                type: CalendarType = .monthly,
                colorSet: CalendarColorSet = DefaultCalendarColorSet(),
                contentColorIndicator: @escaping (_ date: Date) -> Color? = {_ in return nil }) {
        self.init(date: date,
                  selection: selection, 
                  calendar: calendar, 
                  type: type,
                  headerView: { date, calendar in
            DefaultCalendarHeaderView(date, 
                                      calendar: calendar, 
                                      type: type, 
                                      colorSet: colorSet)
        }, weekdaysView: { calendar in
            DefaultWeekdaysHeaderView(headerTextColor: colorSet.weekdayHeaderColor, 
                                      calendar: calendar)
        }) { date, calendar, isDateInMonth, isSelected in
            DefaultDayView(date: date,
                           calendar: calendar,
                           isDateInMonth: isDateInMonth,
                           isSelected: isSelected, 
                           colorSet: colorSet,
                           contentColor: contentColorIndicator(date))
        }
    }
}

This allows me for nice use of given view with injecting default generic types in
as it results with use case such as:

struct ContentView: View {
    @State var currentDate = Date()
    @State var selectedDates: ClosedRange<Date>? = nil
    
    let calendar: Calendar = Calendar.current
    
    var body: some View {
        CalendarView(date: $currentDate, selection: $selectedDates, calendar: calendar)
    }
}

It gives freedom to user without worrying if he needs to create it, which he can if he prefers too.

Is there a way we could add support for this?

Kotlin and Swift handle generics very differently, and constructors pose additional challenges. While we'll continue to enhance the transpiler's abilities over time, we don't have any immediate plans to support constructors in extensions with generic specializations.
