Recently a client submitted his app but was rejected by Apple:
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.
app-prefs:root=wifi
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.
I tried to search for relevant code/setting and the only thing I can find is:
[alertView setBlockSure:^{
NSString * urlString = @"App-Prefs:root=WIFI";
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString]];
}];
And there is no entry under target -> info -> URL Types.
So what is the issue? I read somewhere on Stackoverflow, accessing to WiFi setting directly from an app is considered private? But I can't find recent Apple documentation for valid ones. If not we'll consider opening to just setting instead.
