问题
I have been using Xcode recently when I noticed that the Quick Help tab wasn't showing what is used to show, it was just displaying
Error
Domain=com.apple.DNTDocumentationSupport Code=0 "disk I/O error" UserInfo=
{NSLocalizedDescription=disk I/O error}
I looked up how to fix it, but I got no results.
Does anyone know how to fix this?

I've been facing this issue the past hour or so and the only fix I've found is to restart Xcode. Will report back if it comes back.
