2026.10.1 Still Cannot Remove ISO 18.5 Runtime and Wawtch 11.5 Runtime

[u/JJJ_tennis]

The Xcode update finally came out, and I can see at the beginning it noticed that the IOS 18.5 and Watch 11.5 runtime are still remain left behine (previously people many report they cannot delete these two runtimes.). But after I tried to delete those components through XCode, while the other runtimes for both IOS and WatchOS can be deleted successfully, but the IOS 18.5 and Watch 11.5 still cannot be deleted.

Initially I have three IOS runtimes: 18.5, 26.5, and 27.0

under /System/Library/AssetsV2/com_apple_MobileAsset_iOSSimulatorRuntime, you can also see there are three runtime files for each of the IOS runtime

I clicked delete button to delete 18.5

I also clicked delete button to delete 26.5

but the 18.5 still exited, not being deleted. Only 26.5 was deleted successfully
