Integrating Superwall in React Native Expo (expo-superwall)

Why this skill exists

Superwall’s Expo SDK (expo-superwall) is native-module based, so Expo Go won’t work and setup mistakes often look like “Cannot find native module 'SuperwallExpo'”. This skill provides a reliable, repeatable workflow to:

• install + configure expo-superwall correctly in Expo SDK 53+
• present paywalls via placements (remote campaigns) and implement feature gating
• manage users + attributes, and keep subscription status in sync (including RevenueCat)
• wire deep links / web checkout, and troubleshoot the common integration failures

Non‑negotiables (check first)

1. Expo SDK 53+ is required for expo-superwall.
2. Expo Go is not supported. Use an Expo Development Build (npx expo run:ios|android or EAS dev client).
3. Target minimum OS versions:
   • iOS deployment target: 15.1+
   • Android minSdkVersion: 21+
4. Superwall config does not refetch during hot reload. After dashboard changes (paywalls/products/campaigns), fully restart the app.
