>    Affects Versions: 1.1.0

> If in Safari the Simulator/iPhone is set to automatically show web inspector when the cordova-plugin-wkwebview-engine is in use the app will crash on startup.
> Versions: 
> Safari: 10.0 (12602.1.50.0.10)
> OS X: 10.12 (16A323)
> Xcode: 8.0 (8A218a)
> Cordova: 6.3.1
> Cordova WebKit Engine: 1.1.0
> To repro:
> 1. Create a new test app and add the cordova-plugin-wkwebview-engine plugin to it.
> 2. Open the iOS project in Xcode.
> 3. Run the Simulator.
> If it didn't crash:
> 4. In Safari go to Develop->Simulator->Automatically Show Web Inspector for JSContexts and ensure it's checked.
> 5. Restart the app in Xcode.  It should crash.
> The output in Xcode will be something like:
> {quote}
> testApp(3824,0x1ae6eec40) malloc: *** error for object 0x1700a7e60: pointer being freed was not allocated
> *** set a breakpoint in malloc_error_break to debug
> {quote}
> I spent most of the day trying to repro this consistently because I was seeing the crash on my iPhone but not in the Simulator.  Once I realized it was this setting I'm able to reproduce it consistently on both.
> Also if you remove the CordovaWebViewEngine preference that is set to CDVWKWebViewEngine the app will not crash.
