I have the same problem.

We're seeing this with the InAppBrowser plugin. The plugin is making UI changes within the main WebView thread and the new iOS SDK throws an exception now (instead a warning). Tried wrapping the open method of the plugin in a dispatch_async(...) block but it did not work:

http://stackoverflow.com/questions/28302019/getting-a-this-application-is-modifying-the-autolayout-engine-error

Also, wrapping the method in [self.commandDelegate runInBackground:^{ ... }] did not work:

Any idea how to fix it?

[mhartington]

Have not seen this before, though this might not be the best place to open an issue for it. It sounds like this is a cordova specific issue. Please follow up with the cordova folks and open an issue here.

https://issues.apache.org/jira/browse/CB-9746?jql=project%20%3D%20CB

Closing this for now, if someone could open an issue on their issue tracker with any relevant information, we can follow it up over there.

I've opened up the following thread after no finding any others referencing autolayout: https://issues.apache.org/jira/browse/CB-9769

[maciejwitalinski]

It is a show stopper for me :(

There appears to be a problem with the Swype keyboard extension on iOS 9 causing crashes. I've even been able to get Chrome (outside of Cordova) to crash using this keyboard on iOS 9. I've created a very simple Cordova plugin to prevent third party keyboards from running in the app. This will at least keep the app from crashing.

https://github.com/kurtisf/cordova-plugin-restrict-keyboard

[kurtisf]

Also, if you install the Swype keyboard, and hook up an iPhone to the debugger, when the app crashes, every single time, the keyboard has slid out just to the space bar. It seems at that point there is some code that runs on a background causing the crash.

[mhartington]

@kurtisf nice, thanks for the plugin. I wonder if it would be possible to integrate that code into the keyboard plugin?

[kurtisf]

@mhartington It should be easy enough. I'll need to change the code from being in a category to a swizzle to be more correct. I'll see if I can make a pull request to the keyboard plugin in the next day or two.
