Not really, my issue also appears only in the Simulator – when I tested the app bundle on the real 18.4 Beta/RC device, it worked just fine.
Now, the more I'm testing it, the “trick“ with Info.plist exceptions seems not to work anymore, only setting the .websiteDataStore = .nonPersistent() allows me at least render the desired website right now.
Got a bunch of logged issues on the way, as follows.
1️⃣ Error caught in webView(_:didFailProvisionalNavigation:withError:):

I've just updated to Xcode 16.3 RC 2 & tested (no change), RC Simulator runtime seems like hasn't changed from RC1.
iOS 18.3 Simulator still works fine, even if launched from latest Xcode RC.
Feel free to reach me if needed, I can test whatever I'd be able to, will continue investigating as well. 👍
