3. Code Examples

The following examples demonstrate how to update an app using Xcode for iOS and Android Studio for Android.

### Example 1: Updating your iOS app using Xcode
swift // 1. Open your project in Xcode // 2. Increment the version number in your Project Settings // This is found under the "General" tab of your project // 3. Make necessary code changes // 4. Test your changes on different devices and iOS versions // 5. Archive your app for uploading to the App Store // 6. Submit your updated app for review through App Store Connect
You should expect your updated app to be live on the App Store after it has been reviewed and approved by the App Store team.

### Example 2: Updating your Android app using Android Studio
kotlin // 1. Open your project in Android Studio // 2. Increment the version number in your app-level build.gradle file // This is found under defaultConfig { versionCode int versionName "string" } // 3. Make necessary code changes // 4. Test your changes on different devices and Android versions // 5. Build a signed APK or AAB (Android App Bundle) for your app // 6. Upload your updated app to Google Play Console for review
You should expect your updated app to be live on Google Play Store after it has been reviewed and approved by the Google team.
