Views

Views are the core components of any SwiftUI application. They define the user interface and determine how the app’s content appears onscreen. User interfaces are constructed by organizing views into a hierarchy, starting with high-level containers at the root and extending down to individual elements like text, images, and shapes.

While the concept of a view is common across UI frameworks, SwiftUI takes a unique approach that prioritizes simplicity, lightweight design, and composability. This chapter examines the fundamental principles of SwiftUI views, how they function, and how to effectively compose and customize them to create well-structured and dynamic user interfaces.
