SwiftUI provides a versatile and user-friendly way to implement date pickers in your iOS apps. Let's explore the capabilities of SwiftUI's DatePicker by delving into a Swift code example.

Introduction

The DatePicker in SwiftUI allows users to select dates or times, and it comes with various customization options. In the code snippet provided, we have a DatePickerView containing different sections showcasing the DatePicker's features.

Displayed Components

By specifying the displayedComponents, you can choose whether to show the date, time, or both. For instance:

DatePicker("Default", selection: $date)
DatePicker("Date", selection: $date, displayedComponents: .date)
DatePicker("Time", selection: $date, displayedComponents: .hourAndMinute)

These examples display the default, date-only, and time-only pickers, respectively.

Date Range

You can limit the selectable dates by using the in parameter. For example:

DatePicker("Until Today", selection: $date, in: ...Date(), displayedComponents: .date)
DatePicker("From Today", selection: $date, in: Date()..., displayedComponents: .date)

In these instances, the first DatePicker allows selection up to the current date, while the second one only allows dates starting from today.

Styles

The final section showcases different styles available for the DatePicker. SwiftUI provides styles such as .automatic, .compact, .graphical, and .wheel. Here's how you can apply them:

DatePicker("Graphical", selection: $date, in: ...Date(), displayedComponents: .date)
    .datePickerStyle(.graphical)
// ... other styles

Experiment with these styles to find the one that best suits your application's design.

Reference and Repository

For further details and documentation, you can refer to the official SwiftUI documentation on DatePicker.
