In SwiftUI, views are the fundamental building blocks of user interfaces. They are defined using a declarative syntax, which means you describe what you want the UI to look like, and SwiftUI takes care of rendering it. SwiftUI views are value types, typically defined using structs, and they are compositional and state-driven.
When initializing a SwiftUI view, you often use a view builder, which allows you to construct the content of the view using a trailing closure syntax. This is particularly useful for creating complex UI hierarchies in a concise and readable manner. For example, you can use a List initializer with a collection parameter to create a ForEach view, which generates views for each element in a collection.
For more detailed information on SwiftUI view initialization, you can refer to the SwiftUI essentials session, which covers the fundamentals of views and their declarative nature.
