Hi Jacob,
Thx for your feedback. As the SDK sample app works as expected, I can check internally if the error messages alone is enough to check the issue. Again, unfortunately we don't have the setup and knowlege about Ionic to investigate this very deeply.
Thx and greetings
Nicola
We've been able to reproduce this crash on all of our iOS testing devices.
- iPhone 7+ | iOS 12.4 (Also reproduced on 12.2)
- iPhone X | iOS 12.4
- iPhone 8 | iOS 12.4
- iPhone 6+ | iOS 12.3.1
- iPhone 6+ | iOS 12.+ (cannot verify iOS version at the moment)
This is our own app, not the sample application. The sample application works on all devices.
Unfortunately, it's not exactly simple to just run our application without Ionic as the hooks are too deep at this point.
I hope that helps, I'm happy to answer any other questions.

Hi,
Could you please provide us with further details to these questions:
- What device does this happen with (model details and OS version)?
- Is this happening with the sample app or in your own app? If it happens with your own app, Does the sample app work on your device?
As we're not officially supporting Ionic, does the same issue also occur with the standard Cordova plugin if you work without Ionic? As this might be also related to incopatibilies with Ionic (you mentioned that with a previous SDK it was working without any issues).
Thx and greetings
Nicola

Hello! Inquiring about a crash that happens on iOS.
We are currently on the latest version of the SDK (8.7), Cordova 8.0.0, and Ionic 4.12

That data is fetched via http request and then sent back to the wikitude webview using the WikitudePlugin.callJavascript() function.
This was working perfectly in version 7 of the SDK, but after upgrading we've found that the second or third time this specific call for external data occurs the app crashes. However, we never get a crash on the first request.
I'm not sure if that is related at all, as the crash log above mentions the LocationService and NewLocationEventAvailable.
Here are some additional logs that will hopefully be helpful.
