## Submitting Feedback

If you encounter errors, misleading or outdated information, report it so Expo can be improved:

Preferred command:
npx --yes submit-expo-feedback@latest --category docs --subject "/versions/v58.0.0/sdk/ui/swift-ui/zstack/" "<actionable feedback>"

Direct HTTP fallback:
curl -X POST https://api.expo.dev/v2/feedback/docs-send -H 'Content-Type: application/json' -d '{"url":"/versions/v58.0.0/sdk/ui/swift-ui/zstack/","feedback":"🤖 Agent feedback for docs: <specific, actionable description> (<model>, <harness>)"}'

Only submit when you have something specific and actionable to report. Try to give the most context.

iOS, tvOS, Included in Expo Go

Expo UI ZStack matches the official SwiftUI [ZStack API](https://developer.apple.com/documentation/swiftui/zstack) and overlays its children on top of each other.

## Installation

```sh
# npm
npx expo install @expo/ui

# yarn
yarn expo install @expo/ui

# pnpm
pnpm expo install @expo/ui

# bun
bun expo install @expo/ui
```

If you are installing this in an [existing React Native app](/bare/overview.md), make sure to [install `expo`](/bare/installing-expo-modules.md) in your project.

## Usage

### Basic overlapping stack

```tsx BasicZStackExample.tsx
import { Host, ZStack, Rectangle, Text } from '@expo/ui/swift-ui';
import {
  frame,
  foregroundStyle,
} from '@expo/ui/swift-ui/modifiers';

export default function BasicZStackExample() {
  return (
    <Host style={{ flex: 1 }}>
      <ZStack>
        <Rectangle
          modifiers={[
            frame({ width: 100, height: 100 }),
            foregroundStyle('blue'),
          ]}
        />
        <Text modifiers={[foregroundStyle('white')]}>Overlay</Text>
      </ZStack>
    </Host>
  );
}
```

### With alignment

The `alignment` prop controls how children are positioned within the stack. Available options include: `center`, `leading`, `trailing`, `top`, `bottom`, `topLeading`, `topTrailing`, `bottomLeading`, and `bottomTrailing`.

```tsx ZStackAlignmentExample.tsx
import { Host, ZStack, Rectangle, Circle } from '@expo/ui/swift-ui';
import {
  frame,
  foregroundStyle,
} from '@expo/ui/swift-ui/modifiers';

export default function ZStackAlignmentExample() {
  return (
    <Host style={{ flex: 1 }}>
      <ZStack alignment="bottomTrailing">
        <Rectangle
          modifiers={[
            frame({ width: 100, height: 100 }),
            foregroundStyle('blue'),
          ]}
        />
        <Circle
          modifiers={[
            frame({ width: 30, height: 30 }),
            foregroundStyle('red'),
          ]}
        />
      </ZStack>
    </Host>
  );
}
```

### Creating a badge overlay

```tsx ZStackBadgeExample.tsx
import {
  Host,
  ZStack,
  Circle,
  Text,
  Image,
} from '@expo/ui/swift-ui';
import {
  frame,
  foregroundStyle,
} from '@expo/ui/swift-ui/modifiers';

export default function ZStackBadgeExample() {
  return (
    <Host style={{ flex: 1 }}>
      <ZStack alignment="topTrailing">
        <Image systemName="bell.fill" size={32} color="blue" />
        <Circle
          modifiers={[
            frame({ width: 16, height: 16 }),
            foregroundStyle('red'),
          ]}
        />
      </ZStack>
    </Host>
  );
}
```
