The same happening to me as well. Working fine on iOS 17.5 but not on iOS 18. Refer the below screen shot for iOS 18, whenever i try to hit the local in iOS 18 i gets the error popup saying - Webkit.Networking quit unexpectedly.

No Solution yet, facing the same issue with latest iOS 18.1 Simulators as well

@D4v3m @roomba.friend A temporary solution is to create a new iOS simulator from x-code using iOS 17.5 SDK. Localhost is working fine the iOS versions below iOS 18.0.
