View - thing with the Struct

  • this is a data structure that behaves like a view.
  • view keyword is a behavioral element.
struct ContentView: View{
	var body: some view {
		Text("Hello Samith").padding(20)

in here the text is a function and also adding padding is calling an another functions. so function always returns something. in here text is returning a text view. if we add padding modifier it will return a view that have a padding around it. whats really happening is SwiftUI taking the text view and return it with the modifier view that we have added.

swiftUI is in the functional programming paradigm. so functions are the kings in swiftUI.

  • when working with the swiftUI think all the concepts as Lego set and Lego bricks.
