Which UrbanAirShip version will be compatible with Mono 5.4.1 in Xamarin.Forms?

Hello,

I am trying to implement UrbanAirship in our Xamarin.Forms project. Currently I just want to implement for iOS. I have tried with UrbanAirship and UrbanAirship.portable version 5.0.2. But I am getting following error during building in AppCenter.

MTOUCH : error MT2101: Can’t resolve the reference ‘System.Void ObjCRuntime.BlockLiteral::SetupBlockUnsafe(System.Delegate,System.Delegate)’, referenced from the method ‘UrbanAirship.UAAction UrbanAirship.UAAction::Action(UrbanAirship.UAActionBlock)’ in ‘Xamarin.iOS, Version=0.0.0.0, Culture=neutral, PublicKeyToken=84e04ff9cfb79065’. [/Users/vsts/agent/2.131.0/work/1/s/Source/AsianD8/iOS/MyProject.iOS.csproj]

 

System info:

Visual Studio 2017 Enterprise

Xamarin.Forms

Mono version is 5.4.1.

 

Note: If we remove UrbanAirship DLLs, it builds successfully.

Can anybody please suggest me why I am getting above error and how to resolve it?

If it is issue of compatibility of Mono and UrbanAirship version, can anybody please suggest me which version I should use for Mono version 5.4.1?

    Prakash,

    I just wanted to check, does this same error occur when you build the app in Visual Studio without AppCenter?

    Prakash,

    You may wish to consider just building the project out in Visual Studio rather than through AppCenter. It doesn't look like AppCenter plays nicely with other third-party SDK right now.

    Do you happen to know if using the Sample app that AppCenter provides in their github repo produces any better results?

    Hi Michael,

    Well, I need to build success on AppCenter also. That is must. Anyways, currently I have degrade to UrbanAirship version 4.6.4 and it builds successfully on AppCenter as well.

    Can you please let me know what can be cause?

    One more thing: With UrbanAirship 5.0.2, I always get ChannelID using "UAirship.Push().ChannelID". But in case of version 4.6.4, sometimes I don't get ChannelID using "UAirship.Push.ChannelID".

     

    Please suggest

    Prakash,

    Just to make sure, are you using the latest version of Mono and Visual Studio and AppCenter? Have you tested by updating to Mono 5.8.1?
