How do you remove old Simulators
As it takes up space not used
(Thanks @Ali Yiğit Taş)
I found iOS 15.2.simruntime in /Library/Developer/CoreSimulator/Profiles/Runtimes
But I am running 15.4

Go to Xcode -> Settings... -> Platforms (or Components in newer versions of Xcode) to select and then delete old simulators using the [-] button or right-clicking: 
In Xcode, Window> Devices and Simulators> Simulators. You can delete simulators here that you don't want.
Also, can you try to check /Library/Developer/CoreSimulator/Profiles/Runtimes
Found that you can use "Storage Manager" and or "DevCleaner" Thanks @Larme
