Step 5: Create Lifetime (Non-Consumable)

Before you can sell, you must accept agreements:

  1. Go to Agreements, Tax, and Banking
  2. Accept the Paid Applications agreement
  3. Fill in your Bank Account information
  4. Fill in your Tax Forms (varies by country)

Note

: Products will show "Missing Metadata" until your app is submitted. This is normal.

Part 2: RevenueCat Setup

Step 1: Create RevenueCat Account

  1. Go to RevenueCat
  2. Click Get Started → Sign up
  3. Choose the free tier (covers up to $2,500/month in revenue)

Step 2: Create a Project

  1. After signup, click Create New Project
  2. Enter project name: SelfieCam
  3. Click Create Project

Step 3: Add Your iOS App

  1. In your project, go to Project Settings (gear icon) → Apps
  2. Click + New App
  3. Select App Store (iOS)
  4. Fill in:
    • App Name: SelfieCam
    • Bundle ID: Your exact bundle ID from Xcode (e.g., com.mbrucedogs.SelfieCam)
  5. Click Save Changes

Step 4: Connect to App Store Connect

RevenueCat needs your App Store Connect shared secret to validate receipts:

  1. In App Store Connect, go to your app → App Information (left sidebar)
  2. Scroll to App-Specific Shared Secret → Click Manage
  3. Click Generate if you don't have one
  4. Copy the shared secret
  5. Back in RevenueCat, go to Project Settings → Apps → your iOS app
  6. Paste the shared secret in App Store Connect App-Specific Shared Secret
  7. Click Save Changes

Step 5: Create Products in RevenueCat

  1. Go to Products (left sidebar)
  2. Click + New Product for each:

Product 1 - Monthly:

  • Identifier: com.mbrucedogs.SelfieCam.pro.monthly (must match App Store Connect exactly)
  • App: SelfieCam (iOS)
  • Click Add

Product 2 - Yearly:

  • Identifier: com.mbrucedogs.SelfieCam.pro.yearly
  • App: SelfieCam (iOS)
  • Click Add

Product 3 - Lifetime:

  • Identifier: com.mbrucedogs.SelfieCam.pro.lifetime
  • App: SelfieCam (iOS)
  • Click Add

Step 6: Create an Entitlement

Entitlements represent what the user "gets" - your code checks for this.

  1. Go to Entitlements (left sidebar)
  2. Click + New Entitlement
  3. Enter identifier: Selfie Cam by TopDog Pro (this matches the code in PremiumManager.swift)
  4. Click Add
  5. Now attach all 3 products:
    • Click on the Selfie Cam by TopDog Pro entitlement
    • Click Attach Products
    • Select all 3 products (monthly, yearly, lifetime)
    • Click Attach

Step 7: Create an Offering

Offerings group products for display in your paywall.

  1. Go to Offerings (left sidebar)
  2. You'll see a default offering already exists
  3. Click on default offering
  4. Click + New Package for each:

Package 1:

  • Identifier: Select $rc_monthly from dropdown
  • Product: Select your monthly product
  • Click Add

Package 2:

  • Identifier: Select $rc_annual from dropdown
  • Product: Select your yearly product
  • Click Add

Package 3:

  • Identifier: Select $rc_lifetime from dropdown
  • Product: Select your lifetime product
  • Click Add

Step 8: Get Your API Key

  1. Go to Project Settings (gear icon) → API Keys
  2. Copy your Public App-Specific API Key (starts with appl_)
  3. In your Xcode project, add this to Configuration/Secrets.xcconfig:
REVENUECAT_API_KEY = appl_your_api_key_here

Important

: Never commit Secrets.xcconfig to git. It should be in your .gitignore.

Part 3: Testing Purchases

There are three ways to test purchases without paying real money.

Option A: Debug Premium Toggle (Fastest - No Setup Required)

Use the built-in debug toggle to bypass premium checks entirely:

  1. Run the app in DEBUG mode
  2. Go to Settings → scroll to Debug section
  3. Toggle Enable Debug Premium on
  4. All premium features are now unlocked

This is useful for testing the UI but doesn't test the actual purchase flow.

Option B: StoreKit Configuration File (Local Testing)

Test purchases locally without App Store Connect:

  1. Create a StoreKit Configuration File

    • In Xcode: File → New → File → StoreKit Configuration File
    • Name it Products.storekit
    • Save it in the SelfieCam project folder

  2. Add Your Products Click + in the editor and add:

    Type Reference Name Product ID
    Auto-Renewable Subscription Pro Monthly com.mbrucedogs.SelfieCam.pro.monthly
    Auto-Renewable Subscription Pro Yearly com.mbrucedogs.SelfieCam.pro.yearly
    Non-Consumable Pro Lifetime com.mbrucedogs.SelfieCam.pro.lifetime

    For subscriptions, create a subscription group called "SelfieCam Pro" first.

  3. Enable It in Your Scheme

    • Product → Scheme → Edit Scheme (or ⌘<)
    • Select Run → Options tab
    • Set StoreKit Configuration to your Products.storekit file

  4. Test Purchases

    • Run the app in Simulator or on device
    • Purchases are instant and free
    • Manage transactions: Debug → StoreKit → Manage Transactions

Note

: StoreKit Configuration testing works with RevenueCat but transactions won't appear in the RevenueCat dashboard.

Option C: Sandbox Testing (Full Integration Test)

Test the complete flow with App Store Connect and RevenueCat:

  1. Create a Sandbox Tester Account

    • Go to App Store Connect → Users and Access → Sandbox → Testers
    • Click + to add a new tester
    • Use a fake email you control (not a real Apple ID)
    • Set a password you'll remember

  2. Sign Out of App Store on Your Test Device

    • Settings → App Store → Tap your Apple ID → Sign Out
    • Don't sign back in yet

  3. Run Your App and Make a Purchase

    • Run the app on a physical device (recommended) or simulator
    • Tap a purchase button
    • When prompted to sign in, use your sandbox tester credentials
    • Complete the purchase - it's free!

  4. Verify in RevenueCat

    • Go to RevenueCat dashboard → Customers
    • Search for your sandbox user
    • You should see their entitlement and transaction

Sandbox Subscription Renewal Times:

Real Duration Sandbox Duration
1 week 3 minutes
1 month 5 minutes
2 months 10 minutes
3 months 15 minutes
6 months 30 minutes
1 year 1 hour

Subscriptions auto-renew up to 6 times in sandbox, then expire.

Setup Checklist

App Store Connect

  • App created with correct bundle ID
  • Subscription group created (SelfieCam Pro)
  • Monthly subscription created with price and localization
  • Yearly subscription created with price and localization
  • Lifetime non-consumable created with price and localization
  • Paid Apps agreement accepted
  • Bank and tax info submitted
  • Sandbox tester account created

RevenueCat

  • Account created
  • Project created
  • iOS app added with bundle ID
  • Shared secret from App Store Connect added
  • 3 products created (matching App Store Connect IDs exactly)
  • pro entitlement created
  • All 3 products attached to pro entitlement
  • Default offering has 3 packages (monthly, annual, lifetime)
  • API key copied to Secrets.xcconfig

Xcode

  • Secrets.xcconfig contains REVENUECAT_API_KEY
  • Secrets.xcconfig is in .gitignore
  • (Optional) StoreKit Configuration file created for local testing

Troubleshooting

Products Not Loading

  • Verify product IDs match exactly between App Store Connect and RevenueCat
  • Check that the RevenueCat API key is correctly set in Secrets.xcconfig
  • Ensure the shared secret is added in RevenueCat
  • Products may take a few minutes to propagate after creation

Sandbox Purchases Failing

  • Make sure you're signed out of the regular App Store
  • Use sandbox credentials, not your real Apple ID
  • Check that agreements are accepted in App Store Connect
  • Verify the device isn't in a restricted region

RevenueCat Not Showing Transactions

  • Sandbox transactions can take a minute to appear
  • Verify the bundle ID matches exactly
  • Check that products are attached to the entitlement
  • Look at RevenueCat's debug logs in Xcode console

"Missing Metadata" in App Store Connect

This is normal until you submit your app for review. Products will work in sandbox despite this warning.

Code Reference

The following files handle in-app purchases:

File Purpose
Shared/Premium/PremiumManager.swift RevenueCat integration, purchase logic, customer info listener
Shared/Premium/PaywallPresenter.swift RevenueCat native Paywall with custom fallback
Features/Paywall/Views/ProPaywallView.swift Custom fallback paywall UI
Features/Onboarding/Views/OnboardingSoftPaywallView.swift Onboarding soft paywall
Features/Settings/Views/SettingsView.swift Pro section with Customer Center
Configuration/Secrets.xcconfig RevenueCat API key (not committed to git)

The code checks for a single entitlement called "Selfie Cam by TopDog Pro". All three products (monthly, yearly, lifetime) grant this same entitlement, so the app doesn't need to know which one the user purchased.

RevenueCat Features Used

  • RevenueCat SDK - Core purchase and subscription management
  • RevenueCatUI - Native paywalls and Customer Center
  • PaywallView - Remote-configurable paywall designed in RevenueCat dashboard
  • Customer Center - Subscription management UI (view plan, cancel, request refund)
