@sil/app-release

Shared release automation for iOS app families.

The package owns the repeatable release logic. Each product repo owns its own config, copy, screenshots, launch hooks, signing, Apple IDs, and output paths.

Install

Use from a repo with npx:

npx @sil/app-release --config apps/chess/release/ios.json --mode screenshots
npx @sil/app-release --config apps/chess/release/ios.json --mode promo-video
npx @sil/app-release --config apps/chess/release/ios.json --mode all

For local development:

node /Users/silvandiepen/Repositories/_projects/app-release/app-release.mjs --config apps/chess/release/ios.json --mode preflight

All Apps

Add a repo-owned release.config.json:

{
  "apps": [
    { "slug": "chess", "releaseConfig": "apps/chess/release/ios.json" },
    { "slug": "reversi", "releaseConfig": "apps/reversi/release/ios.json" }
  ]
}

Relative releaseConfig paths resolve from the manifest location. In normal product repos that means paths are usually relative to the repo root.

Then run:

npx -p @sil/app-release app-release-all --mode screenshots
npx -p @sil/app-release app-release-all --mode promo-video --apps chess,reversi

Modes

  • preflight: print paths, config status, upload readiness, and tool availability.
  • validate / verify: run the configured app validation command.
  • screenshots: build the simulator app and capture configured screenshots.
  • site-screenshots: capture screenshots into site/public/screenshots/apps/<app>.
  • promo-video / promo-videos / videos: record or compose promo/App Preview videos.
  • archive: create an Xcode archive and optional IPA export.
  • upload-build: upload a configured IPA with xcrun altool.
  • prepare-metadata: export repo-owned metadata JSON to Fastlane Deliver format.
  • upload-metadata: upload metadata with Fastlane Deliver.
  • prepare-screenshots: copy screenshots into Fastlane Deliver screenshot layout.
  • upload-screenshots: upload screenshots with Fastlane Deliver.
  • distribute: upload build, metadata, and screenshots.
  • all: validate, screenshots, archive, prepare metadata, prepare screenshots.

Every runnable mode checks its own requirements before doing work. Missing tools, paths, environment variables, or config fields are reported per module, for example screenshots, promo-video, archive, or upload-metadata.

Config Ownership

Keep config in the consuming repo.

Recommended per-app file:

apps/<app>/release/ios.json

The app config owns:

  • Xcode project, scheme, bundle ID, product name.
  • App Store Connect Apple ID.
  • validation command.
  • screenshot devices, locales, scenarios, color modes, launch args/env, and output folder.
  • metadata source folder.
  • promo video segments.
  • archive/export/upload settings.

For a full setup checklist, use docs/setup-new-project.md. For every config field currently supported, use docs/config-reference.md.

Screenshot Hooks

Apps can be driven with launch args:

{
  "launchArgs": ["--ui-testing", "--screenshot", "menu"]
}

Or simulator child environment variables:

{
  "env": {
    "MAZZI_SCREENSHOT": "1",
    "MAZZI_SCREENSHOT_ROUTE": "settings"
  }
}

Keys are automatically prefixed with SIMCTL_CHILD_ unless they already start with it.

External Tools

Required for common local capture:

  • Xcode command line tools
  • XcodeGen, when projects are generated from project.yml
  • iOS Simulator runtime

Required for promo videos:

  • FFmpeg
  • ImageMagick when using title, card, or cta segments

Required for uploads:

  • Fastlane for metadata/screenshot upload
  • App Store Connect API credentials for build upload
