Thanks for the response.. I eventually did find the "View/Show LIbrary" option so no worries :>)
I guess it seems odd to me to require developers to perform more steps than before. In Xcode 9 I believe the object library was docked at the bottom-right of the screen so the developer can simply start working with the object library (ie: no clicks required to access). In Xcode 10, the object library could be activated by clicking a button located to the left of the "inspector" buttons (ie: 1 click). Now, in XCode 11, the developer must press "View/Show LIbrary" (two clicks) or "Command-Shift-L" (ie: 3 clicks) to open the object library. It is now more work to open the object library, which seems odd to me since the object library is used often during the design phase. Just my 2 cents though.
Anyway, thanks again for the reply.
