Usable Example Calendar View

[!WARNING] To avoid interfering with the Observable reload mechanism in SwiftUI, let the application control reloads using @State, @StateObject, or Observer directly.

import SwiftUI
import CalendarView

struct ContentView: View {
    @State var isShowHeader = false
    @State var isShowDateOut = false
    @State var firstWeekDate = 1
    @State var viewMode = CalendarViewMode.year
    @State private var selectedDate = Date()
    @State var listSelectedDate = [Date]()

    var body: some View {
        VStack {
            CalendarView(
                date: selectedDate
                , dateView: { date in
                    VStack {
                        Text(date.dayName)
                            .font(.footnote)
                            .fontWeight(.semibold)
                            .foregroundColor(
                                Calendar.current.isDateInWeekend(date) ? .red : .black
                            )
                    }
                    .frame(maxWidth: .infinity)
                    .frame(height: 30)
                    .background(listSelectedDate.contains(date) ? .cyan : .clear)
                }, headerView: { date in
                    VStack {
                        Text(date.weekDayShortName)
                            .font(.footnote)
                            .fontWeight(.bold)
                            .foregroundColor(
                                Calendar.current.isDateInWeekend(date) ? .red : .black
                            )
                    }
                }, dateOutView: { date in
                    Text(DateFormatter.day.string(from: date))
                        .font(.footnote)
                        .foregroundColor(.gray)
                },
                onSelectedDate: onSelectedDate
            )

Customizing the Interface

You can customize the calendar's interface using properties like accentColor, selectedDateColor, and disabledDateColor:

            .enableHeader(isShowHeader)
            .enableDateOut(isShowDateOut)
            .firstWeekDay(firstWeekDate)
            .calendarLocale(Locale(identifier: "vi"))
            .enablePinnedView(.sectionHeaders)
            .setViewMode(viewMode)
            .rowsSpacing(0)
            .columnSpacing(0)
            .backgroundCalendar(.visible(20, .gray.opacity(0.3)))
            .onDraggingEnded { direction, mode in
                if direction == .forward {
                    selectedDate = Calendar.current.date(
                        byAdding: mode == .week ? .weekOfYear : .month,
                        value: 1,
                        to: selectedDate
                    ) ?? selectedDate
                }
            }

Migration Guide

Migrating from v1.x to v2.0

SwiftDate Dependency Removed

The SwiftDate dependency has been removed. Use native Calendar and Date APIs instead:

// Before (SwiftDate)
import SwiftDate
selectedDate = selectedDate.nextWeekday(.friday)

// After (native)
let nextFriday = Calendar.current.nextDate(
    after: selectedDate,
    matching: DateComponents(weekday: 6),
    matchingPolicy: .nextTime
)
selectedDate = nextFriday ?? selectedDate

Renamed APIs

The following APIs have been renamed. Deprecated aliases are provided for backward compatibility:
