Some Apple URL schemes are documented for third-party use. It’s fine to use those URL schemes for their intended purpose.
Other Apple URL schemes are not officially documented. Their use is unsupported. If you rely on such implementation details, things might work, or they might not, and that state might change over time.
IMPORTANT If you ship via the App Store, pay attention to clause 2.5.1 of the App Review Guidelines.
The Apple URL scheme documentation is not always easy to find. I’m aware of the following:
-
QA1924 Opening Keyboard Settings from a Keyboard Extension[This Q&A was retired years ago.] -
The doc comments for
es_new_client
in<EndpointSecurity/ESClient.h>
-
Developer > Bug Reporting describes the
applefeedback
scheme
Additionally, as questions about this most commonly crop up in the context of opening Settings (System Settings on macOS), I wanted to highlight the following:
-
UIApplication.openSettingsURLString
property (in Objective-C this isUIApplicationOpenSettingsURLString
) -
UIApplication.openNotificationSettingsURLString
property (in Objective-C this isUIApplicationOpenNotificationSettingsURLString
) -
FIFinderSyncController.showExtensionManagementInterface()
class method
If your app needs to perform some action that’s not covered by the above, file an enhancement request for a supported way to do that. Make sure to describes your use case in detail.
Share and Enjoy
