What is the difference between a view layout, a website layout, and a needs layout?

In the context of iOS development, layouting refers to three levels of abstraction:

1. View Layout: Defines how user interface elements (such as buttons, labels, images) are arranged and interact with each other on the screen. Implemented using Auto Layout, Stack Views, Grids, Programmatic Layout.

2. Site Flow / Navigation Flow: Describes the sequence of screens and transitions between them in the app. Shows how the user moves between different parts of the app. Visualized with Storyboards, Navigation Controllers, Tab Bar Controllers, SwiftUI Navigation Views.

3. User Needs / Job Stories: Located at the highest level of abstraction and focuses on usage scenarios and user needs. Defines what tasks the user can solve with the app and how the app should function to meet these needs. Implemented through User Stories, Job Stories, Use Cases, low-fidelity prototypes (wireframes).
