Apple App Store: Step by step through the review process

Apple's App Store Guidelines Explained

Apple's App Store Guidelines serve as the rulebook for iOS developers, outlining the standards apps must meet to gain approval. These rules are designed to ensure a "safe experience for users" while maintaining quality across the platform. Following these guidelines not only ensures compliance but also supports the long-term success of your app.

5 Main Categories of Apple's Guidelines

Apple divides its guidelines into five key categories, each focusing on a critical aspect of app development and user experience.

• Safety: This category prioritizes user protection, covering objectionable and user-generated content. Apps must shield users from harmful material like violence, harassment, or inappropriate content. Even physical safety is considered - apps that could harm users or their devices are rejected outright.

• Performance: Apps must operate reliably within Apple's ecosystem. This includes technical stability, feature completeness, and proper use of Apple's APIs. Frequent crashes, broken links, or placeholder content are red flags that violate these standards.

• Business: These rules govern app monetization and interactions with Apple's commerce systems. Apps offering digital goods or services must use Apple's payment system, while physical goods can use alternative methods. In-app purchases, subscriptions, and advertising also fall under this category.

• Design: Apps are expected to follow Apple's Human Interface Guidelines, offering a clean, intuitive user experience. They should provide meaningful functionality - simple web wrappers or apps duplicating existing Apple features often fail the design review.

• Legal: This category addresses intellectual property, privacy, and regulatory compliance. Apps must have proper licensing for content, accurate privacy disclosures, and adhere to local laws. Violations like copyright infringement or privacy issues lead to immediate rejection and potential legal ramifications.

Understanding these categories can simplify the process of meeting Apple's requirements, especially as new updates roll out.

New Compliance Requirements for 2025

Apple has announced updates that developers must implement in 2025 to remain compliant. These changes emphasize user safety and privacy, aligning with Apple's broader goals.

Here are the key deadlines and what they mean for developers:

• April 24, 2025: Submissions must use Xcode 16+ and the latest SDK.

• January 24, 2025: On-device receipt validation must transition to SHA-256.

• February 24, 2025: Update Trust Store for the new APNs server certificate.

• February 17, 2025: Apps targeting the EU must provide trader status for distribution.

• February 18, 2025: macOS apps must remove the quarantine extended file attribute.

Privacy remains a top priority. In Q1 2025, 12% of App Store submissions were rejected for Privacy Manifest violations. Additionally, 94% of users review Privacy Nutrition Labels before downloading, making compliance essential for attracting users.

For developers targeting European markets, the Digital Services Act adds another layer of complexity. Apps without verified trader status will be removed from the App Store in the EU until the issue is resolved.

How to Stay Updated with Guideline Changes

Apple frequently updates its guidelines to address new technologies, user expectations, and regulatory shifts. Staying informed is key to avoiding rejections.

The best way to stay updated is by regularly checking the latest version of Apple's App Store Guidelines on their official website. Apple often announces major updates through developer news channels, providing timelines and technical details to help developers prepare.

Bookmarking the guidelines page and subscribing to notifications or RSS feeds can streamline your monitoring process. The Apple Developer website serves as a central hub for compliance-related announcements.

Regulatory changes, like those driven by the European Union's Digital Services Act, often influence Apple’s policies globally. For instance, the European Commission recently gave Apple 30 days to align its App Store rules with the Digital Markets Act or face penalties. These types of regulations can lead to significant updates in Apple's guidelines.

If Apple flags your app for a guideline violation, act quickly. Developers typically have 90 days to address issues and submit updates. Ignoring these warnings can result in app removal, so proactive monitoring and timely responses are crucial.

Getting Your iOS App Ready for Submission

Submitting your iOS app to the App Store requires careful preparation to meet Apple's technical, localization, and business standards. To avoid setbacks, ensure your app aligns with Apple's guidelines before diving into the submission process.

Technical Requirements Checklist

A solid technical setup is the backbone of a successful App Store submission. Here are the essentials:

• Xcode and SDK Requirements: Your app must be built using Xcode 16 or later, along with the latest SDKs for iOS 18, iPadOS 18, tvOS 18, visionOS 2, or watchOS 11.

• Device Compatibility: iPhone apps should also run seamlessly on iPads to maximize compatibility across Apple's ecosystem.

• Network Support: Ensure your app fully functions on IPv6-only networks, as Apple prioritizes this standard.

• Performance Optimization: Your app should be stable, launch quickly, and offer a responsive user interface while minimizing battery drain. Be vigilant about avoiding memory leaks or excessive CPU usage.

• Privacy and Consent: Apps must obtain clear, explicit user consent before recording or logging any user activity. This includes actions involving the camera, microphone, screen recordings, or other inputs. Provide visible or audible indicators for these activities.

• macOS-Specific Rule: Starting February 18, 2025, macOS apps distributed via TestFlight or the App Store must not include the com.apple.quarantine extended file attribute.

Once your app checks off all these technical requirements, it's time to focus on localization and business details.

Setting Up Your App for U.S. Users

The U.S. is a key market, with iPhones accounting for roughly 60% of the smartphone market share. Tailoring your app for U.S. users involves adapting to local norms and standards.

• Locale Settings: Use the English (U.S.) locale in App Store Connect. This ensures proper formatting for dates (MM/DD/YYYY), currency ($), and measurements (imperial units like feet, pounds, and Fahrenheit).

• Cultural Sensitivity: Design choices should align with U.S. cultural expectations. For instance, while red symbolizes luck in some cultures, it often signals danger in the U.S..

• Language Options: Although English (U.S.) is the default, App Store Connect allows you to add metadata in other languages like Arabic, Simplified and Traditional Chinese, French, Korean, Portuguese (Brazil), Russian, Spanish (Mexico), and Vietnamese. This can help you connect with diverse communities within the U.S.

Updating Business Information in App Store Connect

Before submitting your app, double-check your business details in App Store Connect. Here's what you need to know:

• Editing App Information: Navigate to the Apps section in App Store Connect to update your app's details and platform version information. For shared platform details, go to the "App Information" section under "General."

• Paid Apps Setup: If your app is paid or includes in-app purchases, you'll need to complete additional steps. In the App Store Connect dashboard, click on "Agreements, Tax, and Banking" to set up your payment information.

• European Distribution: If you plan to distribute your app in Europe, trader status verification is required by February 17, 2025. Apple offers three verification methods: Document Review, Domain Validation, or App Store Connect. Domain verification involves adding a TXT record to your DNS zone file to confirm your company’s authority to manage its content.

Finally, keep in mind that your app becomes searchable on the App Store by its name, subtitle, keywords, and your company name. Following these steps ensures a smoother submission process and sets your app up for success.

Meeting Apple's Security and Privacy Requirements

Apple's security and privacy standards are the foundation of App Store compliance. To meet these standards, your app must safeguard user data through strong encryption, transparent privacy practices, and clear user consent mechanisms. These practices not only help you comply with Apple's guidelines but also build trust with users and avoid potential violations. Below, we’ll dive into the key areas of data protection, API usage, and user consent.

Data Security Best Practices

Ensuring data security is a critical step in meeting Apple's guidelines. Sensitive information must be encrypted both when stored and during transmission, using industry-standard protocols. For example, Apple requires the use of App Transport Security (ATS) with TLS 1.2 or higher and recommends SSL pinning to protect against man-in-the-middle attacks.

Store sensitive data securely by using the Keychain and File Protection Classes, which tie access to user authentication. Avoid insecure storage solutions like NSUserDefaults. To enhance security further, implement multi-factor authentication with a combination of passwords, device tokens, and biometrics. Passwords should follow strong policies, be hashed with algorithms like PBKDF2 or Argon2, and sessions should expire after periods of inactivity.

Privacy Manifests and API Usage Requirements

Apple also emphasizes transparency through privacy manifests. Starting May 1, 2024, all iOS apps must include a privacy manifest (PrivacyInfo.xcprivacy) that outlines the data your app collects and the APIs it uses.

"Apps using specific APIs must declare their intended use in a privacy manifest file, effective May 1, 2024." – Apple

To create a privacy manifest, use Xcode 15 or later and navigate to File > New > File > App Privacy File. This file should list all APIs, data types, and tracking domains used by your app and any third-party SDKs. As the developer, you’re responsible for ensuring compliance, even for third-party SDKs. For instance, Firebase Analytics addressed ITMS-91053 errors in version 10.24.0 by fixing issues related to disk space and NSUserDefaults API usage.

Before submitting your app, validate the privacy manifest using Xcode’s Privacy Report (Product > Archive > Generate Privacy Report). This tool helps identify all declared data uses across your app and its dependencies. For example, the CodeWithChris team successfully used this feature while developing a mood tracker app in October 2023, ensuring compliance with Apple’s updated standards. Regular audits are equally important; Spotify reduced app crashes by 15% in just 30 days through precise SDK tracking, while Tilting Point Media faced a $500,000 penalty in June 2024 for improperly configured SDKs that violated privacy laws.

User Consent and Privacy Disclosures

Explicit user consent is a cornerstone of privacy compliance. Apple requires apps to obtain clear permission before accessing personal data. This includes providing transparent explanations about how the data will be used and the security measures in place. Consent requests should be seamlessly integrated into the app’s design, using plain language that’s easy to understand.

When it comes to App Tracking Transparency (ATT), Apple mandates the use of the ATT framework to request tracking permission. Your app must include a clear purpose string explaining why tracking is needed. Additionally, users should have easy access to modify their tracking preferences in the device settings.

"Apps must respect the user's permission settings and not attempt to manipulate, trick, or force people to consent to unnecessary data access." – Apple App Review Guidelines: 5.1.1 (iv)

Real-world examples highlight the importance of thoughtful consent design. For instance, Revolut’s Privacy Dashboard offers real-time toggles for 12 data categories, secured by biometric authentication for sensitive changes. This approach resulted in a 40% opt-in rate for personalized offers. On the other hand, TikTok was fined €345 million in 2024 for using deceptive consent interfaces, commonly referred to as "dark patterns". To avoid such pitfalls, use neutral call-to-action text like "Continue" instead of "Accept All", and ensure accessibility features like VoiceOver compatibility and dynamic text sizing with a minimum 16-point font.

Accessibility is another critical factor. Proper semantic tags should be used to support visually impaired users, ensuring they can navigate consent options effectively. This not only meets Apple’s requirements but also demonstrates respect for all users.

Statistics underscore the importance of proper privacy implementation. In Q1 2025, Apple rejected 12% of App Store submissions for Privacy Manifest violations. Additionally, 94% of users check Privacy Nutrition Labels before downloading an app, and apps with less than a 30% ATT opt-in rate lose an average of 58% in ad revenue.

How to Handle the App Review Process

Once your app meets all technical and security requirements, your next step is navigating the review process. Apple's app review process evaluates everything from new apps and updates to app bundles, in-app purchases, and events. With 90% of submissions reviewed in under 24 hours, understanding the process and avoiding common mistakes can save you time and frustration.

Submitting Your App Through App Store Connect

Here’s a breakdown of the steps to submit your app. Before starting, ensure your app meets Apple's requirements: all iOS and iPadOS apps must be built using Xcode 15 and the iOS 17 SDK.

• Creating Your App Store Connect Record: Start by setting up an App Store Connect account. Add your app through the dashboard, providing details like the platform, app name, primary language, bundle ID, and SKU.

• Archiving and Uploading Through Xcode: In Xcode, select "Generic iOS Device" as your deployment target, then navigate to "Product" > "Archive." Choose "TestFlight & App Store", click "Upload", configure app symbols, and hit "Distribute".

• Configuring Metadata and App Details: In App Store Connect, go to the "App Store" tab to add languages, categories, and your Privacy Policy URL. Use the "Pricing and Availability" page to set pricing, and the "Features" tab to configure options like Game Center. Don’t forget to upload screenshots and write detailed descriptions, keywords, and support URLs.

• Final Submission Steps: Under the "Build" section, select the uploaded build, click "Done", then "Save", and finally "Submit for Review." Answer questions about Export Compliance, Content Rights, and Advertising Identifier before completing the submission.

Track your app’s progress in the Activity > Version History section. Keep in mind, you can only have one active submission per platform at a time, though builds for different platforms can be submitted separately.

Common App Rejection Reasons and How to Avoid Them

Apple rejected 2 million app submissions in 2020 and 1.7 million in 2022, with 40% of rejections related to "App Completeness". Knowing common rejection reasons can help you avoid delays.

Thorough testing can significantly reduce rejection risks. Use TestFlight to test your app across multiple devices. Check for crashes, slow load times, and performance bottlenecks. If your app requires user accounts, provide a demo account for reviewers to ensure smooth evaluation. Finally, focus on creating a high-quality experience to avoid rejection due to generic functionality.

Once you’ve addressed these potential pitfalls, you’ll be ready to handle any feedback from the review process.

How to Respond to App Review Feedback

If your app is rejected, Apple will send a detailed explanation of how it violates the App Review Guidelines or Notarization Review Guidelines. How you respond to this feedback can make all the difference.

• Immediate Response Protocol: Carefully review the rejection message to identify guideline violations. Communicate directly with Apple via the App Review section, attaching screenshots and supporting documents as needed. For metadata issues, you can resubmit the same build after making corrections.

• Crafting Effective Responses: Keep your responses concise and professional. Address each violation with specific evidence, such as screenshots or code changes, to demonstrate how you’ve resolved the issue. Focus on solutions rather than arguing with the review team.

• Real-World Examples: In April 2023, Asana Rebel responded to feedback with a polite and constructive message, starting with, "Hello, we appreciate your feedback". Disney released updates to fix bugs and informed users about the new version. Similarly, a Camera360 user updated their negative review to 5 stars after receiving a thoughtful reply.

• Resubmission Best Practices: Before resubmitting, test all changes thoroughly. Document your resolution process for future reference. When releasing updates that address review issues, include the details in your release notes and reply to relevant reviews to inform users about the fixes. For billing or downloading issues, direct users to Apple Support.

• Timeline Management: Since most submissions are reviewed within 24 hours, respond to feedback promptly to keep the process moving. Pay special attention to reviews with low ratings or those mentioning technical issues, and reply quickly after major updates.
