This is required due to a recent change that Google made.
iOS
Try adding these lines to config.xml:
<platform name="ios">
<edit-config target="NSLocationAlwaysUsageDescription" file="*-Info.plist" mode="overwrite">
<string>Allow the app to know your location</string>
</edit-config>
<edit-config target="NSLocationWhenInUseUsageDescription" file="*-Info.plist" mode="overwrite">
<string>Allow the app to know your location</string>
</edit-config>
<edit-config target="NSCameraUsageDescription" file="*-Info.plist" mode="overwrite">
<string>App would like to access Camera to take picture of any document that you want to upload as attachment to your message</string>
</edit-config>
<edit-config target="NSPhotoLibraryUsageDescription" file="*-Info.plist" mode="overwrite">
<string>Allow the app to open Photo Library to take picture of any document that you want to upload as attachment to your message</string>
</edit-config>
</platform>
iOS now requires permissions in the app before you can use the camera.
These lines have been added to the sample in the next build.
