This ios12 crash happens for us as well although in our case its set as ON_NEXT_RESTART. It cannot be replicated in the simulator, we have just one iPhone 5s with ios12 and... the person is in a different country and does not have a mac.
Do you guys have an advice on what logs to put where to properly capture this?

Comming with an update, we managed to remotely debug it. And we see the same thing kCFErrorDomainCFNetwork 1. Our app is not using the new URL scheme introduced with Cordova iOS 6.

Hello, so I've been digging around and I've noticed that CDVWKWebViewEngine+CodePush.m doesn't seem to be used. I mean in codePush.m on line [self.webViewEngine loadRequest:[NSURLRequest requestWithURL:url]]; it seems to invoke that from CDVWebViewEngine.m. I may be completely off but were are on a deadline here and I am doing what I can to figure this one out.

[pitAlex]

I have a new update. I believe this is a cordova-ios issue or this plugin needs to be updated to overwrite CDVWebViewEngine loadRequest method. I've installed cordova-plugin-ionic-webview, leaving everything as default and the updates worked.
If developers could confirm this, we should open the issue on the cordova-ios repo as well.
