a declarative framework to compose the layout and behavior of multiplatform apps

Features

• Declarative syntax 선언형 문법

  기존의 명령형과 무엇이 다른거지🤔

  "명령형은 코끼리를 냉장고에 넣기 위해서 냉장고 문을 열고 코끼리를 들고 냉장고에 넣고 냉장고 문을 닫는다. 선언형은 코끼리에 냉장고를 넣을거야."

  명령형에 비해 편리하지만 내부적으로 개발자가 컨트롤하지 못하는 부분은 더 많아지는 건가?

• Compositional API

• Powerful layout system

• Views reflect app data

• Automatic accessibility support

SwiftUI automatically includes the animations when pushing and popping from the navigation stack.

@State

You’ll store changes to the scrum in a Data property. You’ll define the property using the @State wrapper because you need to mutate the property from within the view.

SwiftUI observes @State properties and automatically redraws the view’s body when the property changes. This behavior ensures the UI stays up to date as the user manipulates the onscreen controls.
