How to add BlockComment extension for Xcode 11? I'm new at the excode editor. I want to be able to add block comments (/* 
 */), so I found an extension.

But I can't seem to be able to add it to xcode. 

Everything leads me to Xcode -&gt; Preferences -&gt; Extensions but there's nothing there!



Elsewhere, apparently BlockComment should be in the Key Binding section, but it isn't.

Some other research says that I should see BlockComment in the editor drop-down menu and that's not there.

Can this be done?
I found this link to app support at the bottom of the app store page you linked. That should be a go-to place always.

  Reopen Xcode and you can find this extension from Xcode menu.
