Understanding App Store Review Guidelines

Which of the following is NOT a reason for Apple to reject a React Native app during App Store submission?

A Using React Native instead of native Swift or Objective-C

B Including placeholder content instead of real app data

C Having a crash or unresponsive behavior during review

D Using private APIs that are not allowed by Apple

💡 Hint

Apple cares about app behavior and content, not the framework used.

Apple does not reject apps just because they use React Native. They reject apps for private APIs, placeholder content, or crashes.

App Icon Requirements

What will happen if your React Native app's App Store submission includes an icon image that is too small or missing required sizes?

A The app will be rejected due to missing or incorrect icon sizes

B The app icon will automatically resize without issues

C The app will be accepted but the icon will appear blurry on devices

D The app will crash on launch due to icon errors

💡 Hint

Apple requires specific icon sizes for different devices.

Apple requires all required icon sizes to be included. Missing or too small icons cause rejection.

Handling App Review Feedback

After submitting your React Native app, Apple sends feedback that your app crashes on launch. What is the best next step?

A Ignore the feedback and resubmit the same build

B Remove all third-party libraries and resubmit immediately

C Test the app on a real device and fix the crash before resubmitting

D Change the app name and resubmit without code changes

💡 Hint

Apple's feedback is important to fix before resubmission.

Testing on a real device helps find and fix crashes before resubmitting.

App Store Connect Navigation

Where in App Store Connect do you upload your React Native app's IPA file for submission?

A Under the 'Agreements, Tax, and Banking' section

B Under the 'Users and Access' section

C Under the 'My Apps' section, selecting your app, then 'TestFlight' tab

D Under the 'My Apps' section, selecting your app, then 'App Store' tab and 'Prepare for Submission'

💡 Hint

Uploading happens in the app's submission area.

You upload builds in 'Prepare for Submission' under the 'App Store' tab for your app.

Correct Info.plist Configuration for React Native App

Which Info.plist snippet correctly adds the required permission description for camera access in a React Native iOS app to pass App Store review?

A <key>CameraUsageDescription</key><string>Allow camera use.</string>

B <key>NSCameraUsageDescription</key><string>This app requires camera access to take photos.</string>

C <key>NSCameraAccess</key><string>Camera permission needed.</string>

D <key>NSPhotoLibraryUsageDescription</key><string>Camera access required.</string>

💡 Hint

The key must be exactly NSCameraUsageDescription.

Apple requires NSCameraUsageDescription key with a user-friendly message for camera permission.

Practice

1. What is the main purpose of submitting a React Native app to the App Store?

easy

A. To make the app available for millions of iOS users

B. To test the app only on your local device

C. To convert the app into a web application

D. To automatically fix all app bugs

Solution

1. Step 1: Understand App Store submission goal

   Submitting an app to the App Store allows it to be published and accessible to iOS users worldwide.

2. Step 2: Eliminate incorrect options

   Testing locally, converting to web, or auto-fixing bugs are not purposes of submission.

3. Final Answer:

   To make the app available for millions of iOS users -> Option A

4. Quick Check:

   App Store submission = Publish app [OK]

Hint: App Store submission means publishing app for users [OK]

Common Mistakes:

• Thinking submission is only for testing
• Confusing app publishing with app conversion
• Assuming submission fixes bugs automatically

2. Which tool is essential for submitting a React Native app to the Apple App Store?

easy

A. Android Studio

B. Expo Go

C. Visual Studio Code

D. Xcode

Solution

1. Step 1: Identify Apple-specific submission tools

   Xcode is Apple's official tool for building and submitting iOS apps.

2. Step 2: Remove unrelated tools

   Android Studio is for Android apps, VS Code is a code editor, Expo Go is for testing but not submission.

3. Final Answer:

   Xcode -> Option D

4. Quick Check:

   Apple app submission requires Xcode [OK]

Hint: Use Xcode for iOS app submission, not Android Studio [OK]

Common Mistakes:

• Choosing Android Studio for iOS app submission
• Confusing code editors with submission tools
• Thinking Expo Go submits apps to App Store

3. Consider this React Native app submission step: You archive your app in Xcode and upload it to App Store Connect. What happens next?

medium

A. Apple reviews the app before it appears on the store

B. The app is immediately live on the App Store

C. The app is automatically rejected

D. The app is converted to Android format

Solution

1. Step 1: Understand the submission workflow

   After uploading, Apple reviews the app to ensure it meets guidelines.

2. Step 2: Clarify incorrect options

   The app is not live immediately, not automatically rejected, and not converted to Android.

3. Final Answer:

   Apple reviews the app before it appears on the store -> Option A

4. Quick Check:

   App Store review happens after upload [OK]

Hint: App Store review happens before app goes live [OK]

Common Mistakes:

• Assuming instant app availability after upload
• Thinking Apple rejects all apps automatically
• Confusing iOS and Android app processes

4. You submitted your React Native app but it was rejected due to missing app screenshots. What should you do to fix this?

medium

A. Change the app name and resubmit

B. Add required screenshots in App Store Connect and resubmit

C. Delete the app from Xcode and start over

D. Ignore the rejection and submit again

Solution

1. Step 1: Identify the rejection cause

   Missing screenshots means Apple needs images showing app usage.

2. Step 2: Correct the submission details

   Add the required screenshots in App Store Connect, then resubmit for review.

3. Final Answer:

   Add required screenshots in App Store Connect and resubmit -> Option B

4. Quick Check:

   Fix rejection by adding missing info [OK]

Hint: Add all required assets before resubmitting [OK]

Common Mistakes:

• Ignoring rejection reasons
• Deleting app unnecessarily
• Changing unrelated app details

5. You want to submit a React Native app with a new feature that requires user location. What must you include in your App Store submission to avoid rejection?

hard

A. Only mention location use in the app code comments

B. No description is needed if the feature is optional

C. A clear privacy description explaining why location is needed

D. Disable location permissions to avoid review issues

Solution

1. Step 1: Understand Apple's privacy requirements

   Apple requires apps to provide a clear privacy description for sensitive data like location.

2. Step 2: Identify correct submission practice

   Include a privacy usage description in App Store Connect to explain why location is needed.

3. Step 3: Avoid incorrect practices

   Ignoring description, hiding info in code, or disabling permissions are not acceptable.

4. Final Answer:

   A clear privacy description explaining why location is needed -> Option C

5. Quick Check:

   Privacy description required for sensitive data [OK]

Hint: Always add privacy usage descriptions for sensitive features [OK]

Common Mistakes:

• Skipping privacy descriptions
• Thinking optional features don't need explanations
• Hiding info only in code comments
