SwiftUI Picker: The Date Selection Guide

The SwiftUI Picker serves as a versatile tool that allows users to effortlessly choose dates and times. In this tutorial, we will guide you through the process of selecting a future date using the SwiftUI Picker. To get started, ensure you have Xcode 11 and macOS Catalina installed, which can be obtained from the Apple developer portal.

Exploring SwiftUI Picker

• Creating a Date Formatter. To begin, we’ll create a date formatter designed to display dates in a long format, such as “1 Jan 2020.”;
•  Managing the Selected Date. We will also declare a state property to represent the selected date within the date picker. This step is crucial to ensure the accurate capture and display of the selected date.

Let’s dive into the code to see how it’s done:

struct ContentView: View {
    
    // 1.
    var dateFormatter: DateFormatter {
        let formatter = DateFormatter()
        formatter.dateStyle = .long
        return formatter
    }

    // 2.
    @State private var selectedDate = Date()
    
   
    var body: some View {
        VStack {
            Text("Select a future date").font(.largeTitle)
            
            // 3.
            DatePicker(selection: $selectedDate, in: Date()..., displayedComponents: .date) {
                Text("")
            }.padding(30)
            
            // 4.
            Text("Selected Date is \(selectedDate, formatter: dateFormatter)")
                .font(.title)
        }
    }
}

•  We create a date formatter specifying the long date format;
• A state property is declared to represent the selected date within the date picker;
• The date picker is displayed, allowing only future dates to be selected;
• The selected date from the picker view is displayed below the picker.

Now, let’s proceed and explore how to effectively use the SwiftUI Picker.

Utilizing the SwiftUI Picker
