# buttonStyle(_:) Sets the style for buttons within this view to a button style with a custom appearance and standard interaction behavior. ``` nonisolated func buttonStyle(_ style: S) -> some View where S : ButtonStyle ``` ## Discussion Use this modifier to set a specific style for all button instances within a view: ``` HStack { Button("Sign In", action: signIn) Button("Register", action: register) } .buttonStyle(.bordered) ``` You can also use this modifier to set the style for controls that acquire a button style through composition, like the [`Menu`](/documentation/SwiftUI/Menu) and [`Toggle`](/documentation/SwiftUI/Toggle) views in the following example: ``` VStack { Menu("Terms and Conditions") { Button("Open in Preview", action: openInPreview) Button("Save as PDF", action: saveAsPDF) } Toggle("Remember Password", isOn: $isToggleOn) Toggle("Flag", isOn: $flagged) Button("Sign In", action: signIn) } .menuStyle(.button) .toggleStyle(.button) .buttonStyle(.bordered) ``` The [`menuStyle(_:)`](/documentation/SwiftUI/View/menuStyle(_:)) modifier causes the Terms and Conditions menu to render as a button. Similarly, the [`toggleStyle(_:)`](/documentation/SwiftUI/View/toggleStyle(_:)) modifier causes the two toggles to render as buttons. The button style modifier then causes not only the explicit Sign In [`Button`](/documentation/SwiftUI/Button), but also the menu and toggles with button styling, to render with the bordered button style. --- Copyright © 2026 Apple Inc.
