MultiDatePicker in SwiftUI

A MultiDatePicker in SwiftUI allows users to select multiple dates, which can be extremely useful for applications such as event planners, task schedulers, or any scenario where date range selection is necessary. In this tutorial, we’ll walk through creating a unique example of a MultiDatePicker that helps users select dates for a vacation planning app.

Using MultiDatePicker – Simple Vacation Tracker example

In this tutorial, we will explore how to leverage MultiDatePicker to build a user-friendly vacation tracker app. This app will not only help users plan their holidays but also visualize them in a compelling way.

Begin by setting up your SwiftUI view’s structure:

import SwiftUI

struct VacationTrackerView: View {
    @State private var selectedDates: Set<DateComponents> = []

    var body: some View {
        NavigationView {
            VStack {
                multiDatePicker
                selectedDatesList
            }
            .navigationTitle("Vacation Tracker")
            .padding()
        }
    }

    private var multiDatePicker: some View {
        MultiDatePicker(
            "Plan Your Vacations",
            selection: $selectedDates,
            displayedComponents: [.date] // Show only the date component
        )
        .frame(height: 300)
    }

    private var selectedDatesList: some View {
        List(selectedDates.sorted(by: { $0.date! < $1.date! }), id: \.self) { date in
            Text("\(date.date!, formatter: itemFormatter)")
        }
    }
}

// Helper to format the date
private let itemFormatter: DateFormatter = {
    let formatter = DateFormatter()
    formatter.dateStyle = .long
    return formatter
}()

This SwiftUI tutorial introduces you to the MultiDatePicker component, a valuable addition for any developer looking to streamline date selection in their apps. By building a vacation tracker, you learn to integrate multiple date selections with other UI elements, enhancing both functionality and aesthetics.
