Shipping one requires an Apple Developer Program membership and App Store review, and the AASA file must be served over HTTPS on your domain (any HTTPS host works; EAS Hosting is one option). Building via EAS Build or `bunx testflight` uses your EAS plan's build minutes. See https://expo.dev/pricing and https://developer.apple.com/app-clips/.\n\nAdds an iOS App Clip target to an Expo project. The Clip lives in `targets/clip/`, ships alongside the parent app, and is invoked from a URL on the app's domain via an Apple App Site Association (AASA) file.\n\nPreserve the parent's existing bundle ID; derive the Clip's as `<parent>.clip`. Replace the example team, domain, and app identifiers with the project's values.\n\n## 1. Set `bundleIdentifier` and `appleTeamId`\n\n`bun create target` warns if these are missing. Add to `app.json`:\n\n```json\n{\n  \"expo\": {\n    \"ios\": {\n      \"bundleIdentifier\": \"com.<username>.<app-name>\",\n      \"appleTeamId\": \"XX57RJ5UTD\"\n    }\n  }\n}\n```\n\n## 2. Add the App Clip target\n\n```sh\nbunx create-target@3.0.5 clip\n```\n\nThis installs [`@bacons/apple-targets`](https://github.com/EvanBacon/expo-apple-targets), adds it to the `plugins` array in `app.json`, and writes:\n\n- `targets/clip/expo-target.config.js` — the target's config plugin\n- `targets/clip/Info.plist` — Clip Info.plist\n- `targets/clip/AppDelegate.swift`, `Assets.xcassets`, etc.\n\nPick a good icon or reuse the existing one defined in the app — check it with `bunx expo config` under the `icon` or `ios.icon` key.\n\n## 3. Wire up associated domains\n\nThe parent app and the Clip each need the Associated Domains entitlement pointing at the domain that hosts the AASA file.\n\nIn `app.json`, add both `applinks:` (parent) and `appclips:` (Clip invocation) entries:\n\n```json\n{\n  \"expo\": {\n    \"ios\": {\n      \"associatedDomains\": [\n        \"applinks:may20.expo.app\",\n        \"appclips:may20.expo.app\"\n      ]\n    }\n  }\n}\n```\n\nIn `targets/clip/expo-target.config.js`, declare the Clip's entitlement:\n\n```js\n/** @type {import('@bacons/apple-targets/app.plugin').ConfigFunction} */\nmodule.exports = (config) => ({\n  type: \"clip\",\n  icon: \"https://github.com/expo.png\",\n  entitlements: {\n    \"com.apple.developer.associated-domains\": [\"appclips:may20.expo.app\"],\n  },\n});\n```\n\n> If you skip this, `expo prebuild` will print: `Apple App Clip may require the associated domains entitlement but none were found`.\n\n## 4. Register bundle IDs and create the App Store entry\n\n```sh\nbunx setup-safari@0.0.2\n```\n\nThis logs in to the Apple Developer account, registers `com.bacon.may20`, creates the App Store Connect entry, and prints:\n\n- A starter `apple-app-site-association` JSON\n- A `<meta name=\"apple-itunes-app\">` tag with the iTunes app id\n- Team ID, iTunes ID, and Bundle ID\n\n## 5. Host the AASA file\n\nApp Clips are invoked when iOS fetches `https://<your-domain>/.well-known/apple-app-site-association` and finds a matching `appclips` entry.\n\n```sh\nmkdir -p public/.well-known\ntouch public/.well-known/apple-app-site-association\n```\n\nPaste the JSON `setup-safari` printed, but **add an `appclips` block** for the Clip's full app ID (`<TeamID>.<ClipBundleID>`). The output of `setup-safari` only covers the parent app:\n\n```json\n{\n  \"applinks\": {\n    \"details\": [\n      {\n        \"appIDs\": [\"XX57RJ5UTD.com.bacon.may20\"],\n        \"components\": [{ \"/\": \"*\", \"comment\": \"Matches all routes\" }]\n      }\n    ]\n  },\n  \"appclips\": {\n    \"apps\": [\"XX57RJ5UTD.com.bacon.may20.clip\"]\n  },\n  \"activitycontinuation\": {\n    \"apps\": [\"XX57RJ5UTD.com.bacon.may20\"]\n  },\n  \"webcredentials\": {\n    \"apps\": [\"XX57RJ5UTD.com.bacon.may20\"]\n  }\n}\n```\n\nNotes:\n\n- The file has **no extension** and **no `Content-Type` requirements** beyond being served as-is. Expo Router static export serves files in `public/` verbatim.\n- The `appclips` block is what lets a URL on the domain launch the Clip.\n- `webcredentials` is used for sharing credentials between the website, parent app, and the App Clip.\n- `activitycontinuation` is optional and used for sharing the link between mobile and desktop. Must be used with `Head` from expo-router — see https://docs.expo.dev/router/advanced/apple-handoff/\n- Notation and route-disabling details: https://sosumi.ai/documentation/xcode/supporting-associated-domains\n\n## 6. Add the Smart App Banner meta tag\n\nCreate `src/app/+html.tsx` (Expo Router's HTML shell) and add the tag from `setup-safari`. Create the versioned template if it doesn't exist:\n\n```sh\nbunx expo customize src/app/+html.tsx\n```\n\nAdd the meta tag to the `<head>`:\n\n```tsx\nimport { ScrollViewStyleReset } from \"expo-router/html\";\n\nexport default function Root({ children }: { children: React.ReactNode }) {\n  return (\n    <html lang=\"en\">\n      <head>\n        <meta charSet=\"utf-8\" />\n        <meta httpEquiv=\"X-UA-Compatible\" content=\"IE=edge\" />\n        <meta name=\"viewport\" content=\"width=device-width, initial-scale=1\" />\n        <meta name=\"apple-itunes-app\" content=\"app-id=6771566491\" />\n        <ScrollViewStyleReset />\n      </head>\n      <body>{children}</body>\n    </html>\n  );\n}\n```\n\nTo make the website show the App Clip card instead of the install card, use:\n\n```html\n<meta\n  name=\"apple-itunes-app\"\n  content=\"app-id=6771566491, app-clip-bundle-id=com.bacon.may20.clip, app-clip-display=card\"\n/>\n```\n\n## 7. Deploy the website\n\nThe AASA file must be live before iOS will trust the association. Use [EAS Hosting](https://docs.expo.dev/eas/hosting/):\n\n```sh\nbunx expo export -p web\nnpx --yes eas-cli@27.4.1 deploy --prod\n```\n\nThis publishes the site (including `/.well-known/apple-app-site-association`) at `https://<slug>.expo.app`. Verify:\n\n```sh\ncurl https://may20.expo.app/.well-known/apple-app-site-association\n```\n\n## 8. Mirror permissions\n\nInspect the parent app's permissions after prebuild:\n\n```sh\nnpx expo config --type introspect\n```\n\nCopy only the `Info.plist` permission keys needed by the Clip's features.\n\nSet `deploymentTarget: \"17.6\"` in the Clip's target config — App Clips have a higher minimum size limit in iOS 17.6.\n\nIf the app uses push notifications or location services, add to the App Clip's `Info.plist` to request the necessary permissions:\n\n```xml\n<key>NSAppClip</key>\n<dict>\n  <key>NSAppClipRequestEphemeralUserNotification</key>\n  <false/>\n  <key>NSAppClipRequestLocationConfirmation</key>\n  <true/>\n</dict>\n```\n\n## 9. Build and submit to TestFlight\n\n```sh\nbunx testflight@1.0.4\n```\n\nThis will:\n\n1. Generate an `eas.json` if missing.\n2. Set up credentials for **both** targets (parent + Clip). Each gets its own provisioning profile but can share a single Distribution Certificate.\n3. Sync capabilities — note `Enabled: Associated Domains` for the Clip target.\n4. Build, upload, and schedule a TestFlight submission.\n\n## 10. Configure App Clip metadata\n\nPull existing App Store metadata to local:\n\n```sh\nnpx --yes eas-cli@27.4.1 metadata:pull\n```\n\nAdd `apple.appClip` to `store.config.json`. Up to 3 invocation URLs can launch the Clip from a web page:\n\n```json\n{\n  \"configVersion\": 0,\n  \"apple\": {\n    \"appClip\": {\n      \"defaultExperience\": {\n        \"action\": \"PLAY\",\n        \"releaseWithAppStoreVersion\": true,\n        \"reviewDetail\": {\n          \"invocationUrls\": [\"https://may20.expo.app/\", null, null]\n        },\n        \"info\": {\n          \"en-US\": {\n            \"subtitle\": \"Instantly native with Expo\",\n            \"headerImage\": \"store/apple/app-clip/en-US/asc-app-clip.png\"\n          }\n        }\n      }\n    }\n  }\n}\n```\n\nThe `headerImage` must be a 1800x1200 PNG with no opacity.\n\nPush back to the store:\n\n```sh\nnpx --yes eas-cli@27.4.1 metadata:push\n```\n\nApple's recommended App Clip metadata guidelines: https://sosumi.ai/documentation/appclip/configuring-the-launch-experience-of-your-app-clip\n\n## What you get\n\n- Parent app target: `com.bacon.may20`\n- App Clip target: `com.bacon.may20.clip`, lives in `targets/clip/`\n- AASA hosted at `https://may20.expo.app/.well-known/apple-app-site-association`\n- Smart App Banner meta tag on every web route\n- Every route linked to its native counterpart\n- TestFlight build of the parent app with the Clip embedded\n\nOnce Apple invokes the Clip from a URL on the domain, iOS opens `targets/clip/`'s entry point which loads the React Native app.\n\n## Native detection (optional)\n\nTo let JS detect when it's running inside an App Clip and present an install prompt for the full app, create a local Expo module (`bunx create-expo-module --local`) that exposes `navigator.appClip.prompt()`.\n\nSee [./references/native-module.md](./references/native-module.md) for the Swift module, TypeScript interface, and usage.\n\n## References\n\n- ./references/native-module.md — Local Expo module to detect App Clip context and present the SKOverlay install prompt\n\n## Submitting Feedback\nWhen the user requests feedback submission, use:\n```bash\nnpx --yes @expo/agent-cli@1.0.23 feedback --category skills --subject \"expo-app-clip\" \"<actionable feedback>\"\n```\nInclude only relevant technical details; keep credentials, private data, and conversation contents out of feedback.\n"
