Any plans to support this library on SwiftUI?

[bryankeller]

Hi @sethi-ishmeet - this is something that's definitely on our radar. My understanding is that support could be added by wrapping it with UIViewRepresentable. I'll be exploring this in the coming weeks!

Hi @bryankeller I've tried wrapping it into a UIViewRepresentable without any success.. Any updates on how we can make this library working with swiftui ?

[PwBwolf]

This worked for me

import SwiftUI
import HorizonCalendar

struct HorrizonView: UIViewRepresentable {

func makeUIView(context: Context) -> CalendarView {
    let calendarView = CalendarView(initialContent: makeContent())
    return calendarView
}

func updateUIView(_ uiView: CalendarView, context: UIViewRepresentableContext<HorrizonView>) {}

private func makeContent() -> CalendarViewContent {
    let calendar = Calendar(identifier: .gregorian)
    let startDate = calendar.date(from: DateComponents(year: 2020, month: 01, day: 01))!
    let endDate = calendar.date(from: DateComponents(year: 2021, month: 12, day: 31))!
    return CalendarViewContent(
      calendar: calendar,
      visibleDateRange: startDate...endDate,
      monthsLayout: .vertical(options: VerticalMonthsLayoutOptions()))
}

}

Make sure you call struct in the swiftUI view you wish to display it.

 struct DatePickerView: View {
@State private var beginingDate = Date()
@State private var endDate = Date()
var body: some View {
    VStack {
        HStack {
            Text(beginingDate, style: .date)
            Image("arrpwshape.zigzag.right.fill")
            Text(endDate, style: .date)
        }
        HorrizonView()

        Button("Save", action: {
            print("Saving dates")
            print($beginingDate)
        })
    }
}

}

@sethi-ishmeet @PwBwolf if you're still actively using this, a pull request to add this SwiftUI support is welcome since it sounds like you've figured out how to do it 🙂 !

Hi, I have an issue with final class DayRangeIndicatorView: UIView { .. init(indicatorColor: UIColor) { self.indicatorColor = indicatorColor supre.init(frame: frame) // 'self' used in property access 'frame' before 'super.init' call backgroundColor = .clear } }

I write the error message as a comment. Why is this happening?[

use super.init(frame: .zero)

Please add SwiftUI support in it.

            print($beginingDate)
        })
    }
}

}

How can I make the month like January,2020 instead of 2020 M01

[bryankeller]

@YaseenMallick25 your calendar instance doesn't have a locale set. Try using Calendar.current, or add a locale to let calendar = Calendar(identifier: .gregorian).

[YaseenMallick25]

@PwBwolf I used this but still not working . import SwiftUI import HorizonCalendar

struct CalendarViewController: UIViewRepresentable {

func makeUIView(context: Context) -> CalendarView { let calendarView = CalendarView(initialContent: makeContent()) return calendarView }

func updateUIView(_ uiView: CalendarView, context: UIViewRepresentableContext) {}

private func makeContent() -> CalendarViewContent { let calendar = Calendar(identifier: .gregorian) let startDate = calendar.date(from: DateComponents(year: 2020, month: 01, day: 01))! let endDate = calendar.date(from: DateComponents(year: 2021, month: 12, day: 31))! return CalendarViewContent( calendar: calendar, visibleDateRange: startDate...endDate, monthsLayout: .vertical(options: VerticalMonthsLayoutOptions())) }

}

struct CalendarView_Previews: PreviewProvider { static var previews: some View { CalendarViewController() .preferredColorScheme(.dark) } }

[YaseenMallick25]

calendar.locale = Locale(identifier: "en_us") or calendar.locale = Locale.current adding this fixes the problem.

Just wanted to let anyone know who is looking, inorder to use closures like the daySelectionHandler you need to pass the closure into the UIRepresentable and set it up in the makeUIView() function afterwords dont forget to update your calendar in the updateUIView() function

var selectedDay: Day?
    var onSelect: (Day?) -> Void
    func makeUIView(context: Context) -> CalendarView {
        let calendarView = CalendarView(initialContent: self.makeContent())
        calendarView.daySelectionHandler = onSelect
        return calendarView
    }

    func updateUIView(_ uiView: CalendarView, context: UIViewRepresentableContext<CalendarDisplayView>) {
        uiView.setContent(self.makeContent())
    }

    private func makeContent() -> CalendarViewContent {
        let calendar = Calendar.current
        let selectedDay = self.selectedDay
        var dateComponent = DateComponents()

        dateComponent.year = 1
        let futureDate = Calendar.current.date(byAdding: dateComponent, to: self.startDate)!
        return CalendarViewContent(
            calendar: calendar,
            visibleDateRange: self.startDate...futureDate,
            monthsLayout: .horizontal(options: HorizontalMonthsLayoutOptions()))
            .withDayItemModelProvider { day in
                var invariantViewProperties = DayLabel.InvariantViewProperties(
                    font: UIFont.systemFont(ofSize: 18),
                    textColor: .darkGray,
                    backgroundColor: .clear)

                if day == selectedDay {
                    invariantViewProperties.textColor = .white
                    invariantViewProperties.backgroundColor = .blue
                    print("selected")
                }

                return CalendarItemModel<DayLabel>(
                    invariantViewProperties: invariantViewProperties,
                    viewModel: .init(day: day))
            }
    }

What is a DayLable here? with InvariantViewProperties?

What is a DayLable here? with InvariantViewProperties?

DayLable and InvariantViewProperties are the UI of the calendar library for each day of said calendar. InvariantViewProperties allow you to set textColor, backgroundColor and other properties. In my project I used it to modify selected days from their default coloring to an orange color, and for how to decide the selected days I have a date range picker that the client uses and then the calendar reflects it using the new colors.

Thanks! If I got you right i can specify DayLabel by myself for a particular day? and it is not a Horizon Calendar library type.

Ah sorry about the misunderstanding, it is a Horizon Calender Type not a built in native library calendar type.

[AntonVoropaiev]

Thank you so much!

[davidfitz314]

Thank you so much!

No problem, After instantiating the Horizon Calendar, I believe if your using XCode you should be able to cmd click on the Horizon Calendar Day Label or Invariant View Properties to see more of the declared params. Sometimes that's an easier method then looking through the doc online.
