Button

A SwiftUI Button component for displaying native buttons.

iOS

Expo UI Button matches the official SwiftUI Button API and supports styling via the buttonStyle, controlSize, and other modifiers.

Installation

Terminal
npx expo install @expo/ui

If you are installing this in an existing React Native app, make sure to install expo in your project.

Usage

Basic button

BasicButtonExample.tsx
import { Host, Button } from '@expo/ui/swift-ui'; export default function BasicButtonExample() { return ( <Host matchContents> <Button label="Press me" onPress={() => alert('Pressed!')} /> </Host> ); }

Button with system image

ButtonWithImageExample.tsx
import { Host, Button } from '@expo/ui/swift-ui'; export default function ButtonWithImageExample() { return ( <Host matchContents> <Button label="Download" systemImage="arrow.down.circle" onPress={() => alert('Downloading...')} /> </Host> ); }

Icon-only button

Use the labelStyle modifier to show only the icon while keeping the label for accessibility.

IconOnlyButtonExample.tsx
import { Host, Button } from '@expo/ui/swift-ui'; import { labelStyle } from '@expo/ui/swift-ui/modifiers'; export default function IconOnlyButtonExample() { return ( <Host matchContents> <Button label="Settings" systemImage="gear" modifiers={[labelStyle('iconOnly')]} onPress={() => alert('Settings')} /> </Host> ); }

Button styles

Use the buttonStyle modifier to change the button's appearance. Available styles are: bordered, borderedProminent, borderless, plain, glass, and glassProminent.

Note: The glass and glassProminent styles are only available on iOS 26+ when built with Xcode 26.

ButtonStylesExample.tsx
import { Host, Button, VStack } from '@expo/ui/swift-ui'; import { buttonStyle } from '@expo/ui/swift-ui/modifiers'; export default function ButtonStylesExample() { return ( <Host matchContents> <VStack spacing={8}> <Button label="Bordered" modifiers={[buttonStyle('bordered')]} /> <Button label="Bordered Prominent" modifiers={[buttonStyle('borderedProminent')]} /> <Button label="Borderless" modifiers={[buttonStyle('borderless')]} /> <Button label="Plain" modifiers={[buttonStyle('plain')]} /> </VStack> </Host> ); }

Control sizes

Use the controlSize modifier to adjust the button size. Available sizes are: mini, small, regular, large, and extraLarge.

Note: The extraLarge size is only available on iOS 17+.

ControlSizeExample.tsx
import { Host, Button, VStack } from '@expo/ui/swift-ui'; import { buttonStyle, controlSize } from '@expo/ui/swift-ui/modifiers'; export default function ControlSizeExample() { return ( <Host matchContents> <VStack spacing={8}> <Button label="Mini" modifiers={[controlSize('mini'), buttonStyle('bordered')]} /> <Button label="Small" modifiers={[controlSize('small'), buttonStyle('bordered')]} /> <Button label="Regular" modifiers={[controlSize('regular'), buttonStyle('bordered')]} /> <Button label="Large" modifiers={[controlSize('large'), buttonStyle('bordered')]} /> </VStack> </Host> ); }

Button roles

Use the role prop to indicate the semantic role of the button. Available roles are: default, cancel, and destructive.

ButtonRolesExample.tsx
import { Host, Button, VStack } from '@expo/ui/swift-ui'; export default function ButtonRolesExample() { return ( <Host matchContents> <VStack spacing={8}> <Button label="Default" role="default" /> <Button label="Cancel" role="cancel" /> <Button label="Delete" role="destructive" /> </VStack> </Host> ); }

Tinted button

Use the tint modifier to change the button's color.

TintedButtonExample.tsx
import { Host, Button } from '@expo/ui/swift-ui'; import { tint } from '@expo/ui/swift-ui/modifiers'; export default function TintedButtonExample() { return ( <Host matchContents> <Button label="Custom Color" modifiers={[tint('#FF6347')]} /> </Host> ); }

Disabled button

Use the disabled modifier to disable the button.

DisabledButtonExample.tsx
import { Host, Button } from '@expo/ui/swift-ui'; import { disabled } from '@expo/ui/swift-ui/modifiers'; export default function DisabledButtonExample() { return ( <Host matchContents> <Button label="Disabled" modifiers={[disabled()]} /> </Host> ); }

Custom label content

You can pass custom components as children for more complex button label content.

CustomContentExample.tsx
import { Host, Button, VStack, Image, Text } from '@expo/ui/swift-ui'; export default function CustomContentExample() { return ( <Host matchContents> <Button onPress={() => console.log('Pressed!')}> <VStack spacing={4}> <Image systemName="folder" /> <Text>Folder</Text> </VStack> </Button> </Host> ); }
