Assistant Results Not Showing Up

I have Xcode 13 and Mac OS Monterey Beta. For some reasons when I have 2 view controllers, both respective swift files are not showing up. I have tried relinking both of them. What should I do?

What should I do?

In fact, I have experienced similar behaviors even in Xcode 12 on macOS Big Sur. In some of my projects, the pull down menu Assistant abruptly recovered its functionality and now it works as expected.

Maybe some sort of background setups are running behind and we may need to wait them to finish without interrupting it, but I'm not sure.

As a workaround until the functionality will be recovered, you may need to open another Editor side by side and choose the right swift file by yourself.

I fixed it after I cleared my derived data
