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=

app-prefs:root=

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 file an enhancement request.

如果在自己的工程中全局搜索 prefs:root 和 app-prefs:root ，搜不到的话，可能就是第三方的代码中含有私有这些API了。

cd 工程目录

grep -r prefs .（注意此处有个点.）

grep -r App-Prefs .

grep -rn "prefs:root" *

grep -rn "App-Prefs:root" *
