What needs to be updated?

It was fixed by tapping "Install components" however I need to figure out what exactly will be installed and if it can be done via cli

I tried deleting Xcode and reinstalling it. I still get the same error. – Presence

I tried running simulator on an older Mac from which I had migrated. It works fine, showing all the devices. It's also running Big Sur. I didn't try Xcode, which is where I get the error. I only need to get the Simulator to work. – Presence

Did you try opening xcode? It should ask you to install components – Honolulu

As Ted said, I just opened my xcode after the update and clicked on "install" option. After this I tried to build again and all worked fine – Illtempered

I tried it again after seeing this update and I got the install option as well. Problem fixed. It must have been a OS/Xcode update as it didn't do it before. – Presence

Answer 1

As @VictorGazotti said, open Xcode. When it prompts you to install the additional tools, click "Install."

Try the build again.

Answer 2

If you dont see a prompt to install additional tools after opening xcode, try xcodebuild -runFirstLaunch from terminal
