Usage

Import the module

import AvailabilityCalendar

Declare properties for manager

let disabledDates = [Date().addingTimeInterval(86400 * 3),
                     Date().addingTimeInterval(86400 * 5),
                     Date().addingTimeInterval(86400 * 10)] // Not available dates - for example 3, 5, 10 days ahead
let minimumDate = Date() // Minimum today
let maximumDate = Date().addingTimeInterval(86400 * 365) // Year ahead
let selectedDate = Date() // Optional, can be nil
let uiColorSheme = AppStyle.shared.color // App color

Create manager instance

let manager = CalendarManager(minimumDate: minimumDate,
                              maximumDate: maximumDate,
                              disabledDates: disabledDates,
                              selectedDate: selectedDate,
                              uiColorSheme: uiColorSheme)
// Properties for View
let titleText = "Calendar"
let rightButtonText = "Deselect all"
let doneButtonText = "Done"

SwiftUI integraion example

struct ContentView: View {
    var body: some View {
        return CalendarView(titleText: titleText,
                            rightButtonText: rightButtonText,
                            doneButtonText: doneButtonText,
                            manager: manager,
                            dateSelected: { dateSelected in
                if let dateSelected = dateSelected {
                    print(dateSelected)
                }
                else {
                    print("No selected date")
                }
            })
    }
}

UIKit integration example

Import SwiftUI for using UIHostingController

import SwiftUI

Create SwiftUI View

let swiftUIView = CalendarView(titleText: titleText,
                               rightButtonText: rightButtonText,
                               doneButtonText: doneButtonText,
                               manager: manager,
                               dateSelected: { dateSelected in
        self.dismiss(animated: true)
        if let dateSelected = dateSelected {
           print(dateSelected)
        }
        else {
           print("No selected date")
        }
})
// Create UIViewController
let calendarViewController = UIHostingController(rootView: swiftUIView)
self.present(calendarViewController, animated: true)
