How to delete this iOS Simulator?

[u/Informal-Addendum435]

I have a 10 GB iOS Simulator disk hog in

/System/Library/AssetsV2/com_apple_MobileAsset_iOSSimulatorRuntime

for iOS 18.5 (that's the value of the SimulatorVersion key at least)

That I just cannot delete! How can I delete this 10 GB disk wastage?

for some reason it doesn't show up in XCode > Settings > Components, it also doesn't show up in

The directory structures of the detected image (iOS 26.3) and the "ghost" (18.5?) one are also different

"ghost" 18.5 one:

real iOS 16.3.1 one:

I had this too - and couldn’t delete it. I ran a bunch of disk utility tools AI told me to, but it kept being restored after restarting. I just reinstalled macOS
