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>
  );
