Xamarin.iOS project issue

Nasir Ahmed

We have an Xamarin.Forms project.  I have updated the Xamarin.Forms and UrbanAirship  nuget packages to the latest versions. MY .NetStandard and Android  projects are compiling fine. My Xamarin iOS   project is throwing following errors: 

C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\Xamarin\iOS\Xamarin.iOS.Common.targets(795,3): error MT2101: Can't resolve the reference 'Foundation.NSArray Foundation.NSArray::FromNSObjects(!!0[])', referenced from the method 'System.Void UrbanAirship.UAScheduleInfoBuilder::set_Triggers(UrbanAirship.UAScheduleTrigger[])' in 'Xamarin.iOS, Version=0.0.0.0, Culture=neutral, PublicKeyToken=84e04ff9cfb79065'.
2> --- inner exception


 Mono.Linker.MarkException: Error processing method: 'System.Void UrbanAirship.UAScheduleInfoBuilder::set_Triggers(UrbanAirship.UAScheduleTrigger[])' in assembly: 'AirshipBindings.dll' ---> Mono.Cecil.ResolutionException: Failed to resolve Foundation.NSArray Foundation.NSArray::FromNSObjects(!!0[])

Hello Nasir,

May I ask if you can return the following information in order for me to troubleshoot the problem?

- The version of Xamarin.iOS you have installed (I would recommend updating to the latest if you haven't already done so).
- The version of the Airship SDK you are using
- A screenshot of your Project list/solution explorer so I can see which packages are installed and where
 
Kind regards,
