Chapter 27
Building an Image Carousel

The carousel is a common UI pattern found in most mobile and web applications. It is also referred to as an image slider or rotator. Regardless of its name, the carousel is intended to display a set of data within a finite screen space. For instance, an image carousel may showcase a single image from its collection, accompanied by a navigation control that suggests additional content. Users can swipe the screen to navigate through the image set, as is the case with Instagram's presentation of multiple images. Similar carousels can also be found in many other iOS apps, such as Apple's Music and App Store.

This chapter will teach you how to build an image carousel entirely in SwiftUI. There are several methods to implement a carousel, such as integrating with the UIKit component UIPageViewController to create it. However, we will explore an alternative approach and construct the carousel entirely in SwiftUI.

Let's get started.
