1# GitHub Actions Build Artifacts
2 
3## Overview
4 
5Reusable GitHub Actions patterns to build React Native apps for iOS simulators and Android emulators in the cloud, then publish artifacts retrievable via `gh` CLI or GitHub API.
6 
7## When to Apply
8 
9Use this skill when:
10- Creating CI workflows that build React Native simulator/emulator artifacts.
11- Uploading iOS simulator and Android emulator installables from PRs or manual dispatch runs.
12- Replacing local-only mobile builds with downloadable CI artifacts.
13- Needing stable artifact IDs/names for scripted retrieval with `gh` or REST API.

15## Quick Reference
16 
171. Add composite actions from [gha-ios-composite-action.md][gha-ios-composite-action] and [gha-android-composite-action.md][gha-android-composite-action].
182. Wire them into `.github/workflows/mobile-build.yml` from [gha-workflow-and-downloads.md][gha-workflow-and-downloads].
193. Upload with `actions/upload-artifact@v4` and capture `artifact-id` output.
204. Download with `gh run download` or `GET /repos/{owner}/{repo}/actions/artifacts/{artifact_id}/{archive_format}`.
