'View' & 'Modifier' tabs not visible in Library in Xcode

In Xcode, the ‘View’ & ‘Modifier’ tabs are visible initially when I start a project and after some time it disappears from the Library. What could be the reason and how to get the tabs back?
Thanks

Hi @gagan_lumba

Welcome to the community.

Xcode just might be having a bit of a moment so maybe close it and then relaunch it to see if that solves the problem.
