问题
I tried to create new Xcode 8 Source Editor Extension, but for some reason basic examples are always disabled(screenshot) for me and I am not sure whether it is some bug with beta version or I am missing something.
So I created almost basic extension like from WWDC video and sample tutorials, and for some reason this menu item is always disabled.
I ran sudo /usr/libexec/xpccachectl in Terminal and reboot the Mac. I am using 10.11.5 Mac OS.
Also I tested working examples from github like this (Screenshot 2) or this but they are also disabled.

So my questions is: Is that some sort of bug as Xcode 8 is still in beta or some configuration is missing from my side to make extension work?
回答1:
I had the same problem and I think it's just a bug.
This worked in my case: restart Xcode 8, build/run the container app target before, and then run the Xcode extension target.
