SwiftUI ⟩ view ⟩ environment

A view's environment provides access to the view's environment values.

A view inherits its environment from its container view：

• subject to explicit changes from an environment(_:_:) view modifier,

• or by implicit changes from one of the many modifiers that operate on environment values.

As a result, you can configure a entire hierarchy of views by modifying the environment of the group’s container.

// read values from environment
@Environment(\.colorScheme) var colorScheme: ColorScheme
