Moocal is a lightweight SwiftUI calendar library designed to simplify the creation and customization of calendars in your SwiftUI applications. Whether you're building a productivity app, an event planner, or any application that requires calendar functionality, Moocal is your go-to solution. If you want to see an example app using MooCal, see our test app.

Getting Started

Swift Package Manager

1. in XCode go to File -> Add Package Dependencies...

2. In the searchbar paste the github url https://github.com/mazefest/MooCal and select Add Package.

Now you can import MooCal and use the library where ever you like.

Integration

1. Import MooCal

Import MooCal inside of the desired file you are wanting to implement MooCal's features.

import MooCal

2. Setup View

In the view you are wanting to add the scrollable calendar, create a ScrollableCalendarViewViewModel and store it as a variable.

struct ContentView: View {
    var viewModel: ScrollableCalendarViewViewModel
    
    init() {
        self.viewModel = ScrollableCalendarViewViewModel()
    }
    
    var body: some View {

    }
}

Next you will need to initialize the ScrollableCalendarView inside of the var body, it takes in two parameters.

 ScrollableCalendarView(viewModel: ScrollableCalendarViewViewModel, calendarDayView: CalendarDayView)

• viewModel - [ScrollableCalendarViewViewModel] The viewModel we just made above
• calendaryDayView - [CalendarDayView] This determines the view of each individual day inside the calendar

3. Select Calendar Style

In this documentation we are going ot continue on with the Custom calendar day view implementation, but if you are interested in the other offering, checkout the our premade calendar day view implementations below by linking to our wiki.

1. Custom
2. Classic
3. Numbered

4. Implementing Calendar Style (Custom Implementation)

When choosing to use the custom implementation your code will look like the following. The Custom implementation provides a completion handler where you will return the CalendarDay of the view you need to draw, which gives you all you need to create your custom calendar day view, and then you will have to return the View.

var body: some View {
    ScrollableCalendarView(
        viewModel: viewModel,
        calendarDayView: .custom( // <--- HERE
            { calendarDay in
                // Your custom view implementation here
            }
        )
    )
}

Now you will need to provide your custom view to the completion handle. The CalendarDay is going to be vital for doing so. I recommend creating a function that takes in a CalendarDay parameter and returns a view. Forexample:

private func customCalendarDayView(_ calendarDay: CalendarDay) -> some View {
    ZStack {
        RoundedRectangle(cornerRadius: 10.0)
            .foregroundStyle(Color.gray.opacity(0.13))
        Text(calendarDay.descriptor) // The day number. ex: 11
            .bold()
    }
    .aspectRatio(contentMode: .fit)
}

This function will return a rounded rectangle with the numbered day of month centered on top of it.

Next you will need to put this function inside the compltion handler.

var body: some View {
    ScrollableCalendarView(
        viewModel: viewModel,
        calendarDayView: .custom(
            { calendarDay in
                customCalendarDayView(calendarDay) // <-- HERE
            }
        )
    )
}

This will be the result of the above code.
