+# Testing Guide: Iterable iOS Static Linkage Fix
+
+This guide walks you through testing the iOS static linkage changes and the new Expo config plugin.
+
+---
+
+## Prerequisites
+
+Before starting, ensure you have the following installed:
+
+```bash
+# Check Node.js (v18+ recommended)
+node --version
+
+# Check Yarn
+yarn --version
+
+# Check Ruby (for CocoaPods)
+ruby --version
+
+# Check CocoaPods
+pod --version
+
+# Check Xcode CLI tools
+xcode-select -p
+```
+
+If missing any, install them:
+
+```bash
+# Install Node.js via Homebrew
+brew install node
+
+# Install Yarn
+npm install -g yarn
+
+# Install CocoaPods
+sudo gem install cocoapods
+
+# Install Xcode CLI tools (if not installed)
+xcode-select --install
+```
+
+---
+
+## Part 1: Test the React Native SDK Example App
+
+### Step 1: Navigate to the React Native SDK
+
+```bash
+cd /Users/joao.dordio/dev/repos/codereview/ReactNativeStatic/react-native-sdk
+```
+
+### Step 2: Install Dependencies
+
+```bash
+yarn install
+```
+
+### Step 3: Build the SDK (includes plugin)
+
+```bash
+yarn build
+```
+
+This will:
+- Build the React Native SDK with `react-native-builder-bob`
+- Compile the Expo config plugin TypeScript to `plugin/build/`
+
+### Step 4: Verify Plugin Build
+
+```bash
+ls -la plugin/build/
+```
+
+You should see:
+```
+index.js
+index.d.ts
+withIterableAutolinking.js
+withIterableAutolinking.d.ts
+withIterablePodfile.js
+withIterablePodfile.d.ts
+```
+
+### Step 5: Navigate to Example App
+
+```bash
+cd example
+```
+
+### Step 6: Install Example App Dependencies
+
+```bash
+yarn install
+```
+
+### Step 7: Install iOS Pods
+
+```bash
+cd ios
+pod install --repo-update
+cd ..
+```
+
+**Expected output**: Pod installation completes without errors. Look for:
+- `Iterable-iOS-SDK` being installed
+- `Iterable-React-Native-SDK` being installed
+- No "transitive dependencies" errors
+
+### Step 8: Build and Run iOS App
+
+**Option A: Using Yarn (recommended)**
+```bash
+yarn ios
+```
+
+**Option B: Using Xcode**
+```bash
+open ios/ReactNativeSdkExample.xcworkspace
+```
+Then in Xcode:
+1. Select a simulator (e.g., iPhone 15)
+2. Press `Cmd + B` to build
+3. Press `Cmd + R` to run
+
+### Step 9: Verify Build Success
+
+The build should complete without these errors:
+- ❌ `'Iterable_React_Native_SDK-Swift.h' file not found`
+- ❌ `transitive dependencies include statically linked binaries`
+- ❌ Duplicate pod declaration errors
+
+If the app launches in the simulator, the fix is working.
+
+---
+
+## Part 2: Test the Expo Config Plugin
+
+### Step 1: Run Plugin Unit Tests
+
+```bash
+# From the react-native-sdk root
+cd /Users/joao.dordio/dev/repos/codereview/ReactNativeStatic/react-native-sdk
+
+yarn test:plugin
+```
+
+**Expected output**: All tests pass:
+```
+PASS  __tests__/plugin.test.ts
+  withIterableAutolinking
+    disableAutolinking
+      ✓ should add @iterable/react-native-sdk to autolinking exclude list
+      ✓ should preserve existing exclude entries
+      ✓ should be idempotent - not duplicate entries
+  withIterablePodfile
+    ensureStaticLinkage
+      ✓ should keep existing static linkage unchanged
+      ✓ should convert dynamic linkage to static
+      ✓ should convert bare use_frameworks! to static linkage
+    injectIterablePods
+      ✓ should inject Iterable pods after use_expo_modules!
+      ...
+```
+
+### Step 2: Create a Test Expo App (Optional - Full Integration Test)
+
+```bash
+# Create a new directory for testing
+cd /tmp
+npx create-expo-app@latest iterable-expo-test --template blank
+cd iterable-expo-test
+```
+
+### Step 3: Link Local SDK to Test App
+
+```bash
+# Add the local SDK as a dependency
+yarn add /Users/joao.dordio/dev/repos/codereview/ReactNativeStatic/react-native-sdk
+```
+
+### Step 4: Configure the Plugin
+
+Edit `app.json`:
+```json
+{
+  "expo": {
+    "name": "iterable-expo-test",
+    "slug": "iterable-expo-test",
+    "plugins": [
+      ["@iterable/react-native-sdk", { "enableNotificationExtension": true }]
+    ]
+  }
+}
+```
+
+### Step 5: Run Expo Prebuild
+
+```bash
+npx expo prebuild --clean
+```
+
+### Step 6: Verify Podfile Transformation
+
+```bash
+cat ios/Podfile
+```
+
+**Verify these entries exist:**
+
+1. Static linkage is set:
+   ```ruby
+   use_frameworks! :linkage => :static
+   ```
+
+2. Iterable pods with dynamic override:
+   ```ruby
+   # Iterable SDK (Expo Managed Workflow)
+   pod 'Iterable-React-Native-SDK', :path => '../node_modules/@iterable/react-native-sdk', :linkage => :dynamic
+   pod 'Iterable-iOS-SDK', :linkage => :dynamic
+   ```
+
+3. Notification extension target (if enabled):
+   ```ruby
+   target 'IterableNotifications' do
+     use_frameworks! :linkage => :dynamic
+     pod 'Iterable-iOS-AppExtensions'
+   end
+   ```
+
+### Step 7: Test Idempotency
+
+```bash
+# Run prebuild again without --clean
+npx expo prebuild
+
+# Check for duplicates
+grep -c "Iterable-React-Native-SDK" ios/Podfile
+```
+
+**Expected**: Should output `1` (not duplicated)
+
+### Step 8: Build the Expo App
+
+```bash
+npx expo run:ios
+```
+
+---
+
+## Part 3: Verify iOS SDK Header Fix
+
+### Step 1: Navigate to iOS SDK
+
+```bash
+cd /Users/joao.dordio/dev/repos/codereview/ReactNativeStatic/iterable-swift-sdk
+```
+
+### Step 2: Check Header Files Have C++ Guards
+
+```bash
+# Check IterableSDK.h
+grep -A2 "__cplusplus" swift-sdk/IterableSDK.h
+```
+
+**Expected output:**
+```c
+#ifdef __cplusplus
+extern "C" {
+#endif
+```
+
+```bash
+# Check IterableAppExtensions.h
+grep -A2 "__cplusplus" notification-extension/IterableAppExtensions.h
+```
+
+**Expected output:**
+```c
+#ifdef __cplusplus
+extern "C" {
+#endif
+```
+
+### Step 3: Check Resource Bundle Name
+
+```bash
+grep "resource_bundles" Iterable-iOS-SDK.podspec
+```
+
+**Expected output:**
+```ruby
+s.resource_bundles = {'IterableSDKResources' => 'swift-sdk/Resources/**/*.{storyboard,xib,xcassets,xcdatamodeld}' }
+```
+
+---
+
+## Troubleshooting
+
+### Error: `'Iterable_React_Native_SDK-Swift.h' file not found`
+
+This means the C++ linkage fix isn't being picked up. Ensure:
+1. You're using the correct iOS SDK branch: `fix/SDK-290-Export-iOS-sdk-header-file`
+2. Run `pod cache clean --all` and reinstall pods
+
+### Error: Pod install fails with dependency errors
+
+```bash
+cd ios
+pod deintegrate
+pod cache clean --all
+pod install --repo-update
+```
+
+### Error: Plugin build fails
+
+```bash
+# Rebuild the plugin
+cd /Users/joao.dordio/dev/repos/codereview/ReactNativeStatic/react-native-sdk
+rm -rf plugin/build
+yarn build:plugin
+```
+
+### Error: Tests fail with module not found
+
+```bash
+# Install test dependencies
+cd plugin
+yarn add -D ts-jest @types/jest
+```
+
+---
+
+## Quick Commands Reference
+
+```bash
+# Build everything
+cd /Users/joao.dordio/dev/repos/codereview/ReactNativeStatic/react-native-sdk
+yarn install && yarn build
+
+# Run plugin tests
+yarn test:plugin
+
+# Run example app
+cd example && yarn ios
+
+# Clean rebuild
+yarn clean && yarn build
+
+# Check git diff of your changes
+cd /Users/joao.dordio/dev/repos/codereview/ReactNativeStatic/react-native-sdk
+git diff --stat
+```
+
+---
+
+## Success Criteria
+
+You've successfully tested the changes if:
+
+1. ✅ `yarn build` completes without errors
+2. ✅ `yarn test:plugin` - All tests pass
+3. ✅ Example app builds and runs on iOS simulator
+4. ✅ No Swift header file not found errors
+5. ✅ Expo prebuild generates correct Podfile entries
+6. ✅ Running prebuild twice doesn't duplicate entries
