When it comes to developing apps for the Apple ecosystem, ensuring a seamless user experience is crucial. However, in our recent experience, we encountered an unexpected obstacle – our app review was rejected due to non-compliance with App Store Review Guidelines 2.5.2 and 3.3.2. In this article, we'll dive into the reasons behind the rejection and explore ways to optimize your app's user experience.
The Problem: Code Red Flag
During our review process, Apple identified code that could change an app's behavior or functionality after initial approval. This code, combined with remote resources, has the potential to significantly alter an app's behavior, including loading private frameworks, methods, and enabling future feature changes. Although this code may not be malicious in intent, it poses a serious security vulnerability to users.
The Offending Code: A Deep Dive
The offending code in question involves dynamic method calls, such as dlopen(), dlsym(), respondsToSelector:, performSelector:, and method_exchangeImplementations(). These methods allow for significant changes to an app's behavior, which can be exploited by malicious actors. In our case, the Realm SDK was responsible for calling these methods on the native side.
The Solution: Optimizing Your App's User Experience
Fortunately, there are steps you can take to optimize your app's user experience and avoid similar rejections in the future. By removing the offending code and ensuring that your app complies with Apple's guidelines, you can provide a more seamless experience for your users. In our case, we were able to remove the Realm SDK method call, which eliminated the issue.
The Takeaway: A Focus on User Experience
When developing apps for the App Store, it's essential to prioritize user experience and ensure that your app complies with Apple's guidelines. By focusing on creating a seamless and secure experience for your users, you can avoid common pitfalls like this one and build a loyal following of satisfied customers.
