Default Looks Are Fine

SwiftUI gives every button a sensible default style for the platform. But you can reshape its look in seconds with a single modifier. 🎨

The buttonStyle Modifier

Apply a built-in look with the buttonStyle modifier. It changes the whole appearance without you touching the label or action.

Button("Save") { save() }
    .buttonStyle(.bordered)

Bordered for Soft Buttons

The .bordered style draws a soft, tinted capsule around your label. It is great for secondary actions that should look calm.

Button("Cancel") { dismiss() }
    .buttonStyle(.bordered)

Prominent for the Main Action

Use .borderedProminent to make the primary action pop with a filled background. Reserve it for the one button that matters most.

Button("Continue") { next() }
    .buttonStyle(.borderedProminent)

Tinting a Button

Set the accent color of a styled button with the tint modifier. It changes the fill or border to match your brand.

Button("Delete") { remove() }
    .buttonStyle(.borderedProminent)
    .tint(.red)

Controlling Size

The controlSize modifier scales a button between mini, small, regular, and large, so it fits the importance of the action.

Button("Go") { go() }
    .buttonStyle(.bordered)
    .controlSize(.large)

Rounding the Corners

Want a different shape? Pair a style with buttonBorderShape to switch between capsule, rounded rectangle, and more.

Button("Join") { join() }
    .buttonStyle(.bordered)
    .buttonBorderShape(.capsule)

Styling the Label Yourself

For full control, style the label view directly with padding, background, and color, just like any other SwiftUI view.

Button("Buy") { buy() }
    .padding()
    .background(.blue)
    .foregroundStyle(.white)

Order of Modifiers

Modifier order matters. Padding before background gives roomy color; background before padding leaves an outer margin instead.

Plain and Borderless

For a text-only look with no chrome, reach for the .plain style. It strips decoration so only your label shows.

Button("Skip") { skip() }
    .buttonStyle(.plain)

Keep It Consistent

Pick a few styles and reuse them across your app. Consistency helps people instantly know what is tappable and what is primary.

Quick Check

Time to test your styling instincts.

Recap

Great job! Use buttonStyle for built-in looks, tint and controlSize to refine them, or style the label directly for full control. 🎨
