I'm currently developing a custom keyboard which bundled with main app.
The keyboard would randomly crash when switch between apps with opened custom keyboard on physical device.
I've read posts around but seems not what I've encountered.
Bundle ID of main app: com.company.appName
Bundle ID of keyboard extension: com.company.appName.Keyboard
When custom keyboard is opened second time on other app, a sole personality warning would show up, but this won't lead to crash.
WARNING! Sole personality is ambiguous; this may lead to erratic behavior

};
}
After switching between apps for few times, the custom keyboard would crash, common crash log is :
Connection to plugin invalidated while in use.

Another crash log is bit more detailed, but still not sure what it may refers to.
