Changelog

Recommended version:

~57.0.16

Expo UI TabView matches the official SwiftUI TabView API and switches between styles via the tabViewStyle modifier.

Note: For routed bottom-tab navigation across full-screen routes, use expo-router/unstable-native-tabs instead.

Installation

Terminal

- npx expo install @expo/ui

- yarn expo install @expo/ui

- pnpm expo install @expo/ui

- bun expo install @expo/ui

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

Usage

Each page is a <TabView.Tab> child, identified by a value prop. TabView does not impose its own height — give it a frame, or place it inside a parent that does.

Use tabViewStyle({ type: 'page' }) for a horizontal pager with optional dot indicators. Pass defaultSelection to start the pager on a specific page without controlling it from React.

PagerExample.tsx

import {
  Host,
  Spacer,
  TabView,
  Text,
  VStack,
} from '@expo/ui/swift-ui';
import {
  background,
  font,
  foregroundStyle,
  frame,
  tabViewStyle,
} from '@expo/ui/swift-ui/modifiers';

const fillFrame = frame({
  maxWidth: Infinity,
  maxHeight: Infinity,
});
const pageFrame = frame({ minHeight: 320, maxHeight: 320 });

export default function PagerExample() {
  return (
    <Host style={{ flex: 1 }}>
      <TabView
        defaultSelection="1"
        modifiers={[pageFrame, tabViewStyle({ type: 'page' })]}>
        <TabView.Tab value="0">
          <Page label="Page 1" color="#6200EE" />
        </TabView.Tab>
        <TabView.Tab value="1">
          <Page label="Page 2" color="#03DAC5" />
        </TabView.Tab>
        <TabView.Tab value="2">
          <Page label="Page 3" color="#FF5722" />
        </TabView.Tab>
      </TabView>
    </Host>
  );
}

function Page({ label, color }: { label: string; color: string }) {
  return (
    <VStack
      alignment="center"
      modifiers={[fillFrame, background(color)]}>
      <Spacer />
      <Text
        modifiers={[
          font({ size: 28, weight: 'bold' }),
          foregroundStyle('#FFFFFF'),
        ]}>
        {label}
      </Text>
      <Spacer />
    </VStack>
  );
}

Controlled selection

Pass selection and onSelectionChange to drive the active tab from React state. Each <TabView.Tab>'s value is matched against selection. Add the animation modifier to animate transitions when selection changes from JS.

ControlledTabViewExample.tsx

import { useState } from 'react';
import {
  Button,
  Host,
  Spacer,
  TabView,
  Text,
  VStack,
} from '@expo/ui/swift-ui';
import {
  animation,
  Animation,
  background,
  font,
  foregroundStyle,
  frame,
  tabViewStyle,
} from '@expo/ui/swift-ui/modifiers';

const fillFrame = frame({
  maxWidth: Infinity,
  maxHeight: Infinity,
});
const pageFrame = frame({ minHeight: 320, maxHeight: 320 });

export default function ControlledTabViewExample() {
  const [selected, setSelected] = useState('0');

  return (
    <Host style={{ flex: 1 }}>
      <VStack>
        <Text>Selected: {selected}</Text>
        <Button
          label="Go to page 3"
          onPress={() => setSelected('2')}
        />
        <TabView
          selection={selected}
          onSelectionChange={setSelected}
          modifiers={[
            pageFrame,
            tabViewStyle({ type: 'page' }),
            animation(Animation.default, Number(selected)),
          ]}>
          <TabView.Tab value="0">
            <Page label="Page 1" color="#6200EE" />
          </TabView.Tab>
          <TabView.Tab value="1">
            <Page label="Page 2" color="#03DAC5" />
          </TabView.Tab>
          <TabView.Tab value="2">
            <Page label="Page 3" color="#FF5722" />
          </TabView.Tab>
        </TabView>
      </VStack>
    </Host>
  );
}

function Page({ label, color }: { label: string; color: string }) {
  return (
    <VStack
      alignment="center"
      modifiers={[fillFrame, background(color)]}>
      <Spacer />
      <Text
        modifiers={[
          font({ size: 28, weight: 'bold' }),
          foregroundStyle('#FFFFFF'),
        ]}>
        {label}
      </Text>
      <Spacer />
    </VStack>
  );
}

Page indicator dots

Use the indexViewStyle modifier together with tabViewStyle({ type: 'page' }) to control the dot indicators. Set indexDisplayMode to 'always', 'never', or 'automatic', and backgroundDisplayMode to render a translucent pill behind the dots.

PageIndicatorExample.tsx

import {
  Host,
  Spacer,
  TabView,
  Text,
  VStack,
} from '@expo/ui/swift-ui';
import {
  background,
  font,
  foregroundStyle,
  frame,
  indexViewStyle,
  tabViewStyle,
} from '@expo/ui/swift-ui/modifiers';

const fillFrame = frame({
  maxWidth: Infinity,
  maxHeight: Infinity,
});
const pageFrame = frame({ minHeight: 320, maxHeight: 320 });

export default function PageIndicatorExample() {
  return (
    <Host style={{ flex: 1 }}>
      <TabView
        modifiers={[
          pageFrame,
          tabViewStyle({
            type: 'page',
            indexDisplayMode: 'always',
          }),
          indexViewStyle({ backgroundDisplayMode: 'always' }),
        ]}>
        <TabView.Tab value="0">
          <Page label="Page 1" color="#4F8DF6" />
        </TabView.Tab>
        <TabView.Tab value="1">
          <Page label="Page 2" color="#34C759" />
        </TabView.Tab>
        <TabView.Tab value="2">
          <Page label="Page 3" color="#FF9F0A" />
        </TabView.Tab>
      </TabView>
    </Host>
  );
}

function Page({ label, color }: { label: string; color: string }) {
  return (
    <VStack
      alignment="center"
      modifiers={[fillFrame, background(color)]}>
      <Spacer />
      <Text
        modifiers={[
          font({ size: 28, weight: 'bold' }),
          foregroundStyle('#FFFFFF'),
        ]}>
        {label}
      </Text>
      <Spacer />
    </VStack>
  );
}

Bottom tab bar

Use tabViewStyle({ type: 'automatic' }) for the SwiftUI default tab bar. Each tab's label and systemImage populate the bar item. Use the badge modifier on a tab to attach a badge to its bar item.

Note: For routed bottom-tab navigation across full-screen routes, use expo-router/unstable-native-tabs instead.

BottomTabsExample.tsx

import { useState } from 'react';
import {
  Host,
  Spacer,
  TabView,
  Text,
  VStack,
} from '@expo/ui/swift-ui';
import {
  background,
  badge,
  font,
  foregroundStyle,
  frame,
  tabViewStyle,
} from '@expo/ui/swift-ui/modifiers';

const fillFrame = frame({
  maxWidth: Infinity,
  maxHeight: Infinity,
});

export default function BottomTabsExample() {
  const [selected, setSelected] = useState('inbox');

  return (
    <Host style={{ flex: 1 }}>
      <TabView
        selection={selected}
        onSelectionChange={setSelected}
        modifiers={[tabViewStyle({ type: 'automatic' })]}>
        <TabView.Tab
          value="inbox"
          label="Inbox"
          systemImage="tray.fill"
          modifiers={[badge('3')]}>
          <Page label="Inbox" color="#4F8DF6" />
        </TabView.Tab>
        <TabView.Tab
          value="sent"
          label="Sent"
          systemImage="paperplane.fill">
          <Page label="Sent" color="#34C759" />
        </TabView.Tab>
        <TabView.Tab
          value="drafts"
          label="Drafts"
          systemImage="square.and.pencil">
          <Page label="Drafts" color="#FF9F0A" />
        </TabView.Tab>
      </TabView>
    </Host>
  );
}

function Page({ label, color }: { label: string; color: string }) {
  return (
    <VStack
      alignment="center"
      modifiers={[fillFrame, background(color)]}>
      <Spacer />
      <Text
        modifiers={[
          font({ size: 28, weight: 'bold' }),
          foregroundStyle('#FFFFFF'),
        ]}>
        {label}
      </Text>
      <Spacer />
    </VStack>
  );
}

API

import { TabView } from '@expo/ui/swift-ui';

Component

`TabView`

iOS

Type: React.Element<TabViewProps>

A SwiftUI TabView. Pair with modifiers to choose the appearance:

tabViewStyle({ type: 'page' }) — swipeable pager.
tabViewStyle({ type: 'automatic' }) — bottom tab bar.
tabViewStyle({ type: 'sidebarAdaptable' }) — sidebar on iPad, tab bar on iPhone.

Use <TabView.Tab> children to define pages. Each tab is identified by its value prop, which is used for selection.

For routed bottom-tab navigation across full-screen routes, prefer expo-router/unstable-native-tabs.
