Question

Since I installed the iOS 13.2 beta, I have been getting a debug console error message. It happens every time I load a ViewController with a WKWebView objec

Update as of 28 March 2020

Finally Apple deployed something, which not only doesn't shows the error in the logs, but actually allows us; developers to compile, run and submit an application.

Especially, if it's you're coming with Cordova/PhoneGap app combined with any HTML5/JavaScript framework/game (Ionic/Phaser) which wants to run on iOS as web wrapper (my personal experience related to this issue) by using WebView. However, not sure if the same issue applied to NativeScript/React Native or native Java/Kotlin/Swift - these don't need a web wrapper to run.

Nevermind, please update your iPhone/iPad to iOS 13.4 and (!!) Xcode to 11.4. Both of them have been released 3 days ago and can confirm that my Cordova-wrapped app doesn't has the log anymore and doesn't crash.

For historical reasons I'll write a note - the affected iOS versions were: 13.2.X, 13.3.X including its betas. If you're reading this after some time - you need to get rid off those by upgrading to a higher version than 13.3 (recommended) or downgrading to lower version than 13.2 (not recommended). The second option you can use only if Apple for some reason would block you with further updates, e.g. your iPad/iPhone will be really old.
