  1. You are setting <preference name="WKWebViewOnly" value="true" /> but according to the Output FB Hybrid app events cannot be enabled, this feature requires WKWebView and some other it doesn’t seem to work? I assume to research a bit because of this, because i think you want to use WkWebView.
  2. I think the last Log is the Problem, but i’m not sure. Where does it come from? Do you hide the Splash Screen by Code?

Thanks for the reply @EinfachHans

  1. Yes, I Would like to use WkWebView
  2. The splashscreen is being hide on device ready event implement by IONIC, I havent change that part, and its working fine on Android

I will do a bit of research regarding those issues saying I dont have the WKWebView enabled but its very weird

Any news here? I seem to be having the same issue.

I was experiencing the same problem and I solved it by re-installing the iOS platform

ionic cordova platform rm ios
