SwiftUI Custom Modifiers

SwiftUI Custom Modifiers

Create reusable styling and behavior by defining your own ViewModifier types or extension helpers.

Build a reusable ViewModifier

Encapsulate styling in a custom modifier and expose it via a View extension for reuse.

struct CardStyle: ViewModifier {
  func body(content: Content) -> some View {

  .cornerRadius(8)

}

extension View {
  func card() -> some View { modifier(CardStyle()) }
}

  var body: some View { Text("Hello").card() }
