You need think about how to use this private url scheme any more.

What I most care about is "prefs://" which allow users to direct to system settings in the earlier version iOS 7, 8, 9.

I think the hacking method can be workaround this limitation. but I don't know whether the ipa can pass apple submission review.

and of cause I saw a lot of  launcher application on iOS 10 has use the similar workaround. 

e.g:

https://itunes.apple.com/us/app/launcher-notification-center/id905099592?mt=8
see the what's new

What's New in Version 2.2.3

Good news! We now have a workaround for the system launchers that didn't work on iOS 10 and they now work again with this release. Please note that this workaround may be temporary depending on what changes come up in future versions of iOS 10
