Usage

Basic form

BasicFormExample.tsx

import { useState } from 'react';
import { Host, Form, TextField } from '@expo/ui/swift-ui';

export default function BasicFormExample() {
  return (
    <Host style={{ flex: 1 }}>
      <Form>
        <TextField placeholder="Enter your name" />
      </Form>
    </Host>
  );
}

Form with sections

Use the Section component to group related controls within a form.

FormWithSectionsExample.tsx

import { useState } from 'react';
import { Host, Form, Section, TextField, Toggle, Button } from '@expo/ui/swift-ui';

export default function FormWithSectionsExample() {
  const [notifications, setNotifications] = useState(false);
  const [darkMode, setDarkMode] = useState(false);

  return (
    <Host style={{ flex: 1 }}>
      <Form>
        <Section title="Profile">
          <TextField placeholder="Name" />
          <TextField placeholder="Email" />
        </Section>

        <Section title="Preferences">
          <Toggle
            label="Enable notifications"
            isOn={notifications}
            onIsOnChange={setNotifications}
          />
          <Toggle label="Dark mode" isOn={darkMode} onIsOnChange={setDarkMode} />
        </Section>

        <Section>
          <Button label="Save Changes" onPress={() => console.log('Saved!')} />
        </Section>
      </Form>
    </Host>
  );
}

Form with custom background

Use the scrollContentBackground modifier to customize or hide the form's background.

FormBackgroundExample.tsx

import { useState } from 'react';
import { Host, Form, Section, TextField } from '@expo/ui/swift-ui';
import { scrollContentBackground, background } from '@expo/ui/swift-ui/modifiers';

export default function FormBackgroundExample() {
  return (
    <Host style={{ flex: 1 }}>
      <Form modifiers={[scrollContentBackground('hidden'), background('#F0F0F0')]}>
        <Section title="Custom Background">
          <TextField placeholder="Enter text" />
        </Section>
      </Form>
    </Host>
  );
}

Non-scrollable form

Use the scrollDisabled modifier to prevent the form from scrolling.

Note: The scrollDisabled modifier is only available on iOS 16+ and tvOS 16+.

NonScrollableFormExample.tsx

import { useState } from 'react';
import { Host, Form, Section, TextField, Toggle } from '@expo/ui/swift-ui';
import { scrollDisabled } from '@expo/ui/swift-ui/modifiers';

export default function NonScrollableFormExample() {
  const [isOn, setIsOn] = useState(false);

  return (
    <Host style={{ flex: 1 }}>
      <Form modifiers={[scrollDisabled()]}>
        <Section title="Settings">
          <Toggle label="Enable feature" isOn={isOn} onIsOnChange={setIsOn} />
        </Section>
      </Form>
    </Host>
  );
}

Pull-to-refresh form

Use the refreshable modifier to add pull-to-refresh functionality.

RefreshableFormExample.tsx

import { useState, useCallback } from 'react';
import { Host, Form, Section, Text } from '@expo/ui/swift-ui';
import { refreshable } from '@expo/ui/swift-ui/modifiers';

export default function RefreshableFormExample() {
  const [lastRefresh, setLastRefresh] = useState(new Date());

  const handleRefresh = useCallback(async () => {
    // Simulate network request
    await new Promise(resolve => setTimeout(resolve, 1500));
    setLastRefresh(new Date());
  }, []);

  return (
    <Host style={{ flex: 1 }}>
      <Form modifiers={[refreshable(handleRefresh)]}>
        <Section title="Pull to Refresh">
          <Text>Last refreshed: {lastRefresh.toLocaleTimeString()}</Text>
        </Section>
      </Form>
    </Host>
  );
}
