Custom URL Scheme for Settings on iOS 10?

Question

Any Idea what happened to the Setting's Custom URL Scheme on iOS 10? Is Apple still giving acess to third-pary apps to launch iOS Settings from the app via URL Scheme on iOS10? The Old URL scheme are not working anymore!

Answer 1

None of the previous methods for launching the root "Settings" app on iOS 8+ were officially supported by Apple, so unfortunately we can't rely on them. It's also possible that apps that relied on the undocumented behaviors could be rejected during App Store review, even if others have been approved--even if the same app had been previously approved!

I've been unable to discover any workaround either, so it seems your choices are:

1. Open the app-specific URL (as detailed in many places, including @alvin-varghese 's answer above), and then ask the user to navigate backwards. (A terrible user experience, since it involves the user knowing to scroll up from the app list into the main settings sections.)

2. Use an instructional screen or alert in your app to educate users on how to find it themselves. (Not much better, but at least aren't dropped into an unfamiliar context with no waypoints.)

There doesn't seem to be an officially supported way of making this happen in iOS 10, and as you pointed out, it seems like the old ways (adding prefs scheme to your Info.plist file and using openURL(_:)) do not work any more.
