DeadSimpleCalendar

Package provides a CalendarView which can be used to display simple calendar in your App.

You'd have to pass getEventsNumber, getEventsNumberInMonth and perform functions which will be used to:

• getEventsNumbers(Date?) - will be called for each date cell for currently displaying month
• getEventsNumberInMonth(month: Int, year: Int) - will be called for each month/year selection when year mode is selected. month is starting from 0, so you might need to + 1, if you compare to month number obtained from Calendar.current.component().
• perform(Date) - will be called on tap of date cell
• monthChanged(Int) - will be changed when month is scrolled (i.e. changed)

Calendar gets events only for selected month - so if your view model depends on month, use monthChanged to update data

Usage

import DeadSimpleCalendar

// makeMockData() creates random number of events through provided year -> 2021
// number of events for day will change highlighting of cell
let currentYear = DeadSimpleCalendar.getYearFromDate(Date())
let mockEvents = DeadSimpleCalendar.makeMockData(year: currentYear)

struct YourDeadSimpleCalendarView: View {
    // selected date (when user taps on date)
    @State private var selectedDate: Date = Date()
    
    // selected month index (0 -> Jan, 11 -> Dec)
    @State private var selectedMonth: Int = 0
    
    // number of events recorded for selected date
    @State private var eventsForDate: Int = 0
    
    var body: some View {
        let currentYear = DeadSimpleCalendar.getYearFromDate(Date())
        VStack{
            CalendarView(
                getEventsNumber: { date in
                    guard date != nil else { return 0 }

                    if let item = mockEvents[date!] {
                        return item
                    }
                    
                    return 0
                },
                getEventsNumberInMonth: { month_idx, selected_year in
                    
                    var eventsNum = 0
                    
                    mockEvents.forEach { d, events in
                        var month_num = Calendar.current.component(.month, from: d)
                        var year_num = Calendar.current.component(.year, from: d)
                        
                        if  month_num == month_idx + 1 && year_num == selected_year {
                            eventsNum += events
                        }
                    }
                    
                    return eventsNum
                },
                perform: { d in
                    selectedDate = d
                },
                monthChanged: { month in
                    // can be used to update viewModel to query data for selected month
                    selectedMonth = month
                },
                configuration: DeadSimpleCalendarConfiguration(yearRange: (currentYear - 5)...(currentYear + 5))
            )//.border(Color.black)

            VStack(spacing: 5){
                Text("Selected month index: \(selectedMonth)")
                Text("Selected date: \(selectedDate)")
            }.padding()
            Spacer()
        }
    }
}

struct YourDeadSimpleCalendarView_Previews: PreviewProvider {
    static var previews: some View {
        YourDeadSimpleCalendarView()
    }
}

Configuration

You can pass different configruration(DeadSimpleCalendarConfiguration) to CalendarView. For now it supports only yearRange for "year" selection picker. In future I'm thinking to manage style through this struct as well.
