TabView

A SwiftUI TabView component for paged or tabbed content.

iOS

tvOS

Included in Expo Go

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

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.
