Got SIGABRT when executing native xamarin.ios code

Question

I created the xamarin.ios application. The application works absolutely fine. There were no code changes and due to blue, the application now crashes when accessing the camera. I have no idea why this is happening, can anyone shed some light on this problem? I tried this error and searched for various things, including removing various packages. I recently upgraded to ios 10, but the application still worked fine after the upgrade. The error is below:

Answer 1

This is due to the iOS 10 update. You need to request permission for the camera now. The following blog explains how to configure these permissions now.

https://blog.xamarin.com/new-ios-10-privacy-permission-settings/

Starting with iOS 10, almost all APIs that require authorization authorization and other APIs, such as opening a camera or photo galleries, require a new pair of key values ​​to describe their use in Info.plist. This is very similar to the requirement of NSLocationWhenInUseUsageDescription or NSLocationAlwaysUsageDescription, which must be placed in Info.plit when using the Geolocation and iBeacon APIs. Now the difference is that the application will crash when the application tries to authenticate without these keys.
