After I upgraded to Xcode 10 the Quick Help information only provide declaration of the selected class or structure.

Is there a setting somewhere that I can make it same as what it was in Xcode 9?

I had the same issue after upgrading where the function signature is the only thing showing when doing an option click. Quick Help reappeared when I deleted everything inside ~/Library/Developer/Xcode/DerivedData as well as in ~/Library/Caches/com.apple.dt.Xcode. You need to quit xcode first btw. Hope this helps.

  • Yes, I have downloaded Xcode 9.4.1. Expanded the folder. But where is your ~/Library folder? I want to do some comparisons – Paul Sep 21 '18 at 01:04
  • I found it. But the problem isn't in the Xcode folder. It is in /Library/Developer/PrivateFrameworks/CoreSimulator.framework. I cannot find this folder in Xcode package – Paul Sep 21 '18 at 01:08
