Hello,
Thank you for resubmitting your app for review.
Guideline 2.5.1 - Performance - Software Requirements
Your app uses the "prefs:root=" non-public URL scheme, which is a private entity. The use of non-public APIs is not permitted on the App Store because it can lead to a poor user experience should these APIs change.
Specifically, your app uses the following non-public URL scheme:
prefs:root=about
Continuing to use or conceal non-public APIs in future submissions of this app may result in the termination of your Apple Developer account, as well as removal of all associated apps from the App Store.
Next Steps
To resolve this issue, please revise your app to provide the associated functionality using public APIs or remove the functionality using the "prefs:root" or "App-Prefs:root" URL scheme.
If there are no alternatives for providing the functionality your app requires, you can use Feedback Assistant to submit an enhancement request.
在提交版本中，一个同事因为使用了通讯录权限，在代码里有一段未使用的跳转代码，包含了私有API；通过搜索代码prefs:root 找到了这段代码 删除了 然后重新提交 审核通过。
