Select Device name -> Select Device model -> iOS version -> Create Simulator.

It will show a list of iOS available for the device.

Simulator menu -> File -> New Simulator.

Go to -> Xcode menu -> Open Developer tool -> Simulator

Then start installing whichever iOS version would like to install.

Go to component tab shown like below picture 👇🏻.

So, I tried the simplest thing which generally all apps have an option to search inside the app. But all of the answers do not look straight forward. While doing google found one StackOverflow question which was having same issue. When we selected to add a new Simulator then the iOS option was coming only iOS 14 no other option to add. Because Xcode 12 came with iOS 14 default version. Not able to find an option to add devices which support iOS older versions like 12,13 etc. Today's I came across an issue while upgrading Xcode 11 to 12.
