Layout

The layout system in SwiftUI determines how views size and position themselves on the screen. Instead of manually setting dimensions, SwiftUI uses a structured process where parent and child views collaborate to define their sizes and placements. This approach makes layouts flexible and adaptable to different content and screen sizes.

In this chapter, we cover the core principles of SwiftUI’s layout system, including how views calculate their size and position, the behavior of built-in containers like stacks and grids, and how to create custom layouts using the Layout protocol. These concepts form the foundation for building responsive and structured user interfaces.
