We have exactly the same issue here. Same Wikitude sdk version. XCode 9.4.1

This is a critical blocking issue.

Thanks, have a nice day.


Are the two of you adding any additional Xamarin Components/NuGet packages besides Wikitude?

Best regards,

we successfully fixed the issue on our own, the Xamarin iOS binding Library provided by Wikitude is not up to date with a recent change in Xamarin.iOS (

We started by downloading the Wikitude iOS Javascript SDK. Then we use Objective Sharpie with the WikitudeSDK.framework file to generate C# classes. Then we created a Xamarin.iOS binding library project. With a few adjustments and adding AutoGeneratedName = true to the  [Model] attributes it is now working.

We had this issue with both Wikitude 8.0.0 Xamarin and 7.2.1 Xamarin.

Tell me if you're interested and i will share the iOS DLL ;-)

Thanks, have a nice day.

Hi Jean-Pierre,

Thx for the link! We're about to rewrite the Wikitude SDK Xamarin binding to deliver a better/initial NuGet package. I added the link as a reference to consider it when we rewrite the package.

Best regards,
