.modifier(YourCustomModifier()) to apply complex styling in one line, making your views cleaner and more maintainable.Custom ViewModifiers encapsulate complex styling logic into reusable components. This approach creates a consistent design system where card styling is centralized and can be easily modified across the entire app.
struct CardStyle: ViewModifier {
let isElevated: Bool
func body(content: Content) -> some View {
content
.padding(16)
.background(Color(.systemBackground))
.cornerRadius(12)
.shadow(
color: isElevated ? .black.opacity(0.1) : .clear,
radius: isElevated ? 8 : 0,
y: isElevated ? 4 : 0
)
.overlay(
RoundedRectangle(cornerRadius: 12)
.stroke(Color(.separator), lineWidth: 0.5)
)
}
}
extension View {
func cardStyle(elevated: Bool = true) -> some View {
modifier(CardStyle(isElevated: elevated))
}
}
// Usage
VStack {
Text("Card Content")
.cardStyle()
Text("Flat Card")
.cardStyle(elevated: false)
}By composing multiple modifiers into a single custom modifier, you ensure visual consistency, reduce code duplication, and make design changes scalable. When you need to update card styling, you only modify one place instead of hunting down scattered styling code throughout your app.
