Is it possible to "Debug View Hierarchy" in Xcode for an app extension?

Question

I'm trying to debug the view hierarchy in an app extension, but I don't get anything useful.

Are there any limitations to using this feature with extensions?

If not, what could I possibly be doing wrong? I have the feeling there might be since the app is actually running inside a third party's UI. Would this be to keep people from "looking inside someone else's app"?

No, it seems not possible at this time. On Xcode8 iOS10, it shows nothing for keyboard extension.

An alternative choice is Reveal. On latest version, it supports App Extension. Actually it is what I am using right now.
