The reason an iOS app might pass local environment tests but get rejected during the App Store review is due to the stringent guidelines and policies that Apple enforces. These guidelines cover various aspects including design, functionality, privacy, security, and content. Even if an app functions perfectly on a developer's local device or simulator, it might still violate one or more of Apple's guidelines.
For example, an app might include inappropriate content, such as explicit material or hate speech, which would be acceptable in a local test environment but is strictly forbidden by Apple's content guidelines. Another common reason is the use of private APIs or functionalities that are not meant for public use, which might work locally but are detected during the review process.
Additionally, Apple reviews apps for compliance with their privacy and data handling policies. An app might collect user data without proper consent or in a way that doesn't align with Apple's requirements, leading to rejection.
To ensure smooth approval, developers should thoroughly review and adhere to Apple's App Store guidelines and ensure that their app complies with all relevant policies before submission. Utilizing services like Tencent Cloud's cloud-based solutions can also help in managing data securely and efficiently, reducing the risk of non-compliance related rejections.
