ButtonStyle & LabelStyle

Build branded, reusable control styles.

ButtonStyle & LabelStyle is a free SwiftUI Academy lesson on CoddyKit — lesson 3 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the SwiftUI Academy learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.

Style Controls, Not Instances

Restyling every button by hand gets tedious. A ButtonStyle defines one branded look you reuse across the whole app. 🎨

The ButtonStyle Protocol

Conform a struct to ButtonStyle and implement makeBody. It receives a configuration and returns the styled button.

struct PrimaryStyle: ButtonStyle {
    func makeBody(configuration: Configuration) -> some View {
        configuration.label
    }
}

The label Inside Configuration

The configuration gives you the buttons label, which is the title or content. You decorate that label with padding and color.

configuration.label
    .padding()
    .background(.blue)

React to isPressed

Configuration also exposes isPressed. Use it to dim or scale the button while a finger is down for tactile feedback.

configuration.label
    .opacity(configuration.isPressed ? 0.6 : 1)

Apply with buttonStyle

Attach your style with the .buttonStyle modifier. Every button it touches adopts the same branded appearance.

Button("Save") { }
    .buttonStyle(PrimaryStyle())

Style a Whole Container

Set .buttonStyle on a stack and every button inside inherits it. One line styles a full group of controls.

Built-in Styles Exist Too

SwiftUI ships ready styles like .bordered and .borderedProminent. Reach for those before writing a custom one.

Button("Go") { }
    .buttonStyle(.borderedProminent)

Now Meet LabelStyle

A Label pairs text with an icon. A LabelStyle controls how that pair is arranged and shown.

Label("Home", systemImage: "house")

Title-Only or Icon-Only

Built-in label styles let you show just the title, just the icon, or both. Switch based on space without changing the call site.

Label("Home", systemImage: "house")
    .labelStyle(.iconOnly)

Custom LabelStyle

Conform to LabelStyle and implement makeBody to rearrange the icon and title yourself, like stacking them vertically.

func makeBody(configuration: Configuration) -> some View {
    VStack { configuration.icon; configuration.title }
}

One Definition, Many Buttons

Custom styles keep look and behavior in one place. Tweak the style and every button or label across the app updates together.

Recap: Reusable Control Looks

Use ButtonStyle and LabelStyle to define branded controls once. React to isPressed, rearrange labels, and apply the look everywhere. 🧠
