Installing Mobile Preview Builds

Install Mobile Preview Build (iOS)

Use this skill to create a fresh local preview iOS build and install it on a connected iPhone.

Inputs

• Optional $ARGUMENTS: device identifier (UDID or exact device name).
• If no argument is provided, auto-select the first paired iPhone from xcrun devicectl list devices.

Workflow

1. Validate repo and tooling.

   • Run from repo root and ensure apps/mobile exists.
   • Verify pnpm, xcrun, xcodebuild, and eas-cli are available.
   • Verify EAS login:

     cd apps/mobile
     pnpm dlx eas-cli whoami
     

2. Resolve target device.

   • List paired devices:

     xcrun devicectl list devices
     

   • Choose device in this order:
     • $ARGUMENTS if provided and matches exactly one device.
     • Otherwise, first paired iPhone.

3. Trigger local preview iOS build.

   mkdir -p .context/preview-install
   cd apps/mobile
   pnpm dlx eas-cli build -p ios --profile preview --non-interactive --local --output=./build-preview.ipa
   cd ../..
   cp apps/mobile/build-preview.ipa .context/preview-install/folo-preview.ipa
   

4. Install to device locally.

   unzip -q -o .context/preview-install/folo-preview.ipa -d .context/preview-install/unpacked
   APP_PATH=$(find .context/preview-install/unpacked/Payload -maxdepth 1 -name '*.app' -type d | head -n 1)
   xcrun devicectl device install app --device "<device-id>" "$APP_PATH"
   

5. Try launching app.

   xcrun devicectl device process launch --device "<device-id>" is.follow --activate
   

   • If launch fails due to locked device, instruct the user to unlock iPhone and open Folo manually.

Failure Handling

• If local build fails, report:
  • build mode (local)
  • failing command
  • key error message from command output
• If app config fails with Assets source directory not found ... /out/rn-web, prebuild assets then retry once:

  pnpm --filter @follow/rn-micro-web-app build --outDir out/rn-web/html-renderer
  

Output Format

Always return:

1. Build mode (local) and final status.
2. Local IPA path.
3. Target device identifier.
4. Install result (installed or failed) and launch result.
5. Next action for the user if manual action is required.
