UserInterface

UserInterface (UI)

(UI) refers to the way that an app looks and how it presents itself to the user. It includes all of the visual elements of the app, such as buttons, labels, text fields, and other controls, as well as the layout and arrangement of those elements on the screen.

The UI of an iOS app is created using UIKit, a framework provided by Apple that includes a wide range of pre-built UI elements and layout tools. Developers can use UIKit to create a wide variety of user interfaces, from simple, static layouts to more complex, interactive interfaces.

UIKit provides a number of tools for creating and managing the UI of an iOS app

• View

• View controllers

• UI Controles

• Auto Layout

• Animations

there are two ways can create UI components in Xcode

StoryBoard
Storyboards are a visual tool for designing the user interface of an iOS app. They allow you to see the layout and flow of your app's screens in a single place, and create connections between them using segues. Storyboards are a good choice for prototyping and quickly iterating on the design of an app, as they provide a fast and intuitive way to see the changes you make.

Code
you can create complex layouts and animations that may be difficult to achieve with a storyboard. It also allows you to reuse components of your user interface in different parts of your app, by creating custom views and view controllers. However, manual code can be more time-consuming to write and maintain, as you'll need to manually manage the layout and behaviour of your user interface elements.

the choice between using a storyboard and manual code will depend on the specific needs of your app and your personal development style. Some developers prefer the visual and rapid prototyping capabilities of storyboards, while others prefer the flexibility and control of manual code.
