# Deploy Expo iOS Apps with EAS

iOS release work for Expo apps requires EAS profiles, credentials, TestFlight steps, and version rules. This skill gives focused checklists and commands for build, submit, OTA updates, and troubleshooting.

## Install

```bash
npx skillstore add cjharmath/expo-build-deploy

## Capabilities

- Shows initial EAS CLI setup commands for Expo iOS projects.
- Provides example EAS build and submit profiles.
- Explains development, preview, production, and local iOS build flows.
- Lists TestFlight, App Store Connect, and App Store submission steps.
- Documents OTA update channels, version increments, and common EAS troubleshooting commands.

## Use Cases

- Create a First iOS Build: Set up EAS for an Expo app and choose the right build profile.
- Prepare TestFlight Delivery: Review App Store Connect fields, credentials, build numbers, and submit steps before tester release.
- Resolve Build and Update Issues: Use targeted checks for signing errors, stuck processing, crashes, and OTA update delivery.

## Prompt Templates

### Set Up iOS Builds

```
Help me configure EAS Build for my Expo iOS app. Include the needed project files, profiles, and first build checks.
```

### Prepare TestFlight Submission

```
Create a TestFlight submission plan for my Expo app. Cover credentials, build number, App Store Connect fields, and review steps.
```

### Troubleshoot Build Failure

```
My Expo iOS build failed during signing. Walk me through likely causes, credential checks, and safe recovery steps.
```

### Audit Release Workflow

```
Review my Expo iOS release workflow. Identify gaps in build profiles, OTA channels, versioning, credentials, and App Store submission readiness.
```

## Limitations

- Focuses on iOS workflows and does not cover Android release setup.
- Provides static guidance and does not verify Apple or Expo account state.
- Uses example identifiers, URLs, and secrets that must be replaced before use.
- Does not replace Expo, Apple, or App Store policy documentation.

## Best Practices

- Confirm the target EAS profile before every build or submission.
- Keep private keys on a backend and expose only public client configuration.
- Increase iOS build numbers for every App Store upload.

## Anti Patterns

- Do not paste private API keys into client-visible Expo config.
- Do not reset signing credentials without confirming team ownership and impact.
- Do not publish OTA updates to production without matching the release channel.

## Security Audit

- Audited at: 2026-07-05T07:55:02.574\+00:00
- Summary: Static command and network detections are mostly Markdown documentation false positives; the file contains no executable Ruby backtick code or autonomous outbound requests. The main confirmed risk is unsafe secret-handling guidance that can expose API keys through Expo client config and command history. No prompt injection language was found in SKILL.md.
