GitHub Actions Build Artifacts

Overview

Reusable 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.

When to Apply

Use this skill when:

Creating CI workflows that build React Native simulator/emulator artifacts.
Uploading iOS simulator and Android emulator installables from PRs or manual dispatch runs.
Replacing local-only mobile builds with downloadable CI artifacts.
Needing stable artifact IDs/names for scripted retrieval with
```
gh
```
or REST API.

Quick Reference

Add composite actions from gha-ios-composite-action.md and gha-android-composite-action.md.
Wire them into
```
.github/workflows/mobile-build.yml
```
from gha-workflow-and-downloads.md.
Upload with
```
actions/upload-artifact@v4
```
and capture
```
artifact-id
```
output.

Download with

gh run download

GET /repos/{owner}/{repo}/actions/artifacts/{artifact_id}/{archive_format}
