App review guidelines in iOS Swift - Build, Publish & Deploy

Build & Publish - App review guidelines

Performance Impact

Following app review guidelines ensures your app runs smoothly without unexpected crashes or slowdowns. Apps that misuse resources or have poor performance often get rejected. Maintaining good performance helps keep frame rates at 60fps, reduces memory use below 1.5GB, and preserves battery life.

Optimization Tips

To meet guidelines and keep your app fast, optimize startup time by lazy loading features, minimize background tasks, and use efficient data handling. Test on real devices to ensure smooth UI and quick response. Avoid blocking the main thread and use asynchronous calls for network or heavy tasks.

App Size and Startup Time

Apple recommends keeping app bundles small, ideally under 100MB for over-the-air downloads. Large apps delay installation and startup, risking rejection. Use app thinning, compress assets, and remove unused code to reduce size. Fast startup improves user experience and meets guideline expectations.

iOS vs Android Differences

iOS apps require strict adherence to Apple Human Interface Guidelines and privacy rules. Code signing and provisioning profiles are mandatory. The App Store review usually takes 24-48 hours. Android apps have more flexible UI rules but require APK/AAB signing and Google Play review times vary from hours to days.

App Store Review Checklist

• Functionality: App must be complete, stable, and free of bugs.
• Content: No offensive or illegal content allowed.
• Privacy: Must include a privacy policy and request user permissions clearly.
• User Interface: Follow Apple's Human Interface Guidelines for layout and navigation.
• Performance: Smooth animations, no crashes, and efficient memory use.
• Metadata: Accurate app description, screenshots, and keywords.
• Legal: Comply with copyright and intellectual property laws.

Self-Check Question

Your app takes 5 seconds to load this screen. What's likely wrong?

• Heavy synchronous tasks blocking the main thread.
• Large uncompressed assets loading at startup.
• Network calls done on the main thread instead of asynchronously.
• Lack of lazy loading for non-essential features.

Key Result

Following Apple's app review guidelines ensures your app is stable, respects user privacy, and meets performance standards, which helps pass review quickly and provides a smooth user experience.
