----------------------------------
Summary: cordova-plugin-wkwebview-engine crashes app on startup if
Safari is set to "Automatically Show Web Inspector for JSContexts"
Key: CB-11897
URL: https://issues.apache.org/jira/browse/CB-11897
Project: Apache Cordova
Issue Type: Bug
Components: iOS, Plugin WKWebViewEngine
Affects Versions: 1.1.0
Environment: iOS
Reporter: Brad Reynolds
Assignee: Shazron Abdullah
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.
