Hover-click not working in playground
In my Xcode (version 11.4.1), I do not get anything when I however over an element, holding option, and clicking. I see the question mark appear over the object, but no further info comes up.
This happens quite a lot - it can sometimes be cured with a force quit of Xcode, but sometimes you need to reset the entire system. It can also be solved by clicking the project / playground file directly in finder as opposed to the 'recent' items in Xcode. Annoying I know, but you get used to it!
