Expo UI Swift UI

expo-ui-swift-ui

Overview

This public intake copy packages plugins/antigravity-awesome-skills-claude/skills/expo-ui-swift-ui from https://github.com/sickn33/antigravity-awesome-skills into the native Omni Skills editorial shape without hiding its origin.

Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.

This intake keeps the copied upstream files intact and uses the external_source block in metadata.json plus ORIGIN.md as the provenance anchor for review.

--- name: expo-ui-swift-ui description: @expo/ui/swift-ui package lets you use SwiftUI Views and modifiers in your app. --- > The instructions in this skill apply to SDK 55 only. For other SDK versions, refer to the Expo UI SwiftUI docs for that version for the most accurate information.

Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: Limitations.

When to Use This Skill

Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.

• You need to build iOS-native UI in Expo using @expo/ui/swift-ui.
• The task involves selecting SwiftUI views or modifiers, wrapping trees in Host, or embedding React Native components with RNHostView.
• You are targeting Expo SDK 55 behavior for SwiftUI integration and extension guidance.
• Use when the request clearly matches the imported source intent: expo-ui-swift-ui.
• Use when the operator should preserve upstream workflow detail instead of rewriting the process from scratch.
• Use when provenance needs to stay visible in the answer, PR, or review packet.

Operating Table

Workflow

This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow.

1. Expo UI's API mirrors SwiftUI's API. Use SwiftUI knowledge to decide which components or modifiers to use.
2. Components are imported from @expo/ui/swift-ui, modifiers from @expo/ui/swift-ui/modifiers.
3. When about to use a component, fetch its docs to confirm the API - https://docs.expo.dev/versions/v55.0.0/sdk/ui/swift-ui/{component-name}/index.md
4. When unsure about a modifier's API, refer to the docs - https://docs.expo.dev/versions/v55.0.0/sdk/ui/swift-ui/modifiers/index.md
5. Every SwiftUI tree must be wrapped in Host.
6. RNHostView is specifically for embedding RN components inside a SwiftUI tree. Example:
7. If a required modifier or View is missing in Expo UI, it can be extended via a local Expo module. See: https://docs.expo.dev/guides/expo-ui-swift-ui/extending/index.md. Confirm with the user before extending.

Imported Workflow Notes

Imported: Installation

npx expo install @expo/ui

A native rebuild is required after installation (npx expo run:ios).

Imported: Instructions

• Expo UI's API mirrors SwiftUI's API. Use SwiftUI knowledge to decide which components or modifiers to use.
• Components are imported from @expo/ui/swift-ui, modifiers from @expo/ui/swift-ui/modifiers.
• When about to use a component, fetch its docs to confirm the API - https://docs.expo.dev/versions/v55.0.0/sdk/ui/swift-ui/{component-name}/index.md
• When unsure about a modifier's API, refer to the docs - https://docs.expo.dev/versions/v55.0.0/sdk/ui/swift-ui/modifiers/index.md
• Every SwiftUI tree must be wrapped in Host.
• RNHostView is specifically for embedding RN components inside a SwiftUI tree. Example:

import { Host, VStack, RNHostView } from "@expo-ui/swift-ui";
import { Pressable } from "react-native";

<Host matchContents>
  <VStack>
    <RNHostView matchContents>
      // Here, `Pressable` is an RN component so it is wrapped in `RNHostView`.
      <Pressable />
    </RNHostView>
  </VStack>
</Host>;

• If a required modifier or View is missing in Expo UI, it can be extended via a local Expo module. See: https://docs.expo.dev/guides/expo-ui-swift-ui/extending/index.md. Confirm with the user before extending.

Imported: Limitations

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.

Examples

Example 1: Ask for the upstream workflow directly

Use @expo-ui-swift-ui to handle <task>. Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer.

Explanation: This is the safest starting point when the operator needs the imported workflow, but not the entire repository.

Example 2: Ask for a provenance-grounded review

Review @expo-ui-swift-ui against metadata.json and ORIGIN.md, then explain which copied upstream files you would load first and why.

Explanation: Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection.

Example 3: Narrow the copied support files before execution

Use @expo-ui-swift-ui for <task>. Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding.

Explanation: This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default.

Example 4: Build a reviewer packet

Review @expo-ui-swift-ui using the copied upstream files plus provenance, then summarize any gaps before merge.

Explanation: This is useful when the PR is waiting for human review and you want a repeatable audit packet.

Best Practices

Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution.

• Keep the imported skill grounded in the upstream repository; do not invent steps that the source material cannot support.
• Prefer the smallest useful set of support files so the workflow stays auditable and fast to review.
• Keep provenance, source commit, and imported file paths visible in notes and PR descriptions.
• Point directly at the copied upstream files that justify the workflow instead of relying on generic review boilerplate.
• Treat generated examples as scaffolding; adapt them to the concrete task before execution.
• Route to a stronger native skill when architecture, debugging, design, or security concerns become dominant.

Troubleshooting

Problem: The operator skipped the imported context and answered too generically

Symptoms: The result ignores the upstream workflow in plugins/antigravity-awesome-skills-claude/skills/expo-ui-swift-ui, fails to mention provenance, or does not use any copied source files at all. Solution: Re-open metadata.json, ORIGIN.md, and the most relevant copied upstream files. Check the external_source block first, then restate the provenance before continuing.

Problem: The imported workflow feels incomplete during review

Symptoms: Reviewers can see the generated SKILL.md, but they cannot quickly tell which references, examples, or scripts matter for the current task. Solution: Point at the exact copied references, examples, scripts, or assets that justify the path you took. If the gap is still real, record it in the PR instead of hiding it.

Problem: The task drifted into a different specialization

Symptoms: The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better. Solution: Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind.
