Xamarin.iOS binding for a swift library

I am creating a binding for a swift library to be used in a xamarin project. When i consume the binding project in the ios project, I get the following error:

Dyld Error Message:
Library not loaded: @rpath/Alamofire.framework/Alamofire
Referenced from: 
/Users/USER/Library/Developer/CoreSimulator/Devices/73CDF7FB-D700-4F35- 
AB8B-DD7F7B134C1E/data/Containers/Bundle/Application/9FB74CDE-93C3- 
4EB7-9833- FA060281CE46/XXXXXXXX.iOS.app/Frameworks/MobiiiSDK.framework/MobiiiSDK
Reason: image not found

I have added https://github.com/Flash3001/Xamarin.Swift to my project to reference swift libraries.

Have set both SmartLink and ForceLink to true

I have deleted the obj and bind folders in all projects. Did a clean and rebuild too.

I would appreciate any help to fix this error.

This might not be the direct answer to your question but can definitely take you in the right direction, here is the Office UI Fabric Xamarin.iOS Swift binding project that you can use as reference, it does not use (need) the Xamarin.Swift but uses a msbuild script that uses swift-stdlib-tool which is the tool that Xcode uses to determine what swift libraries need to be bundled with your application. The script [1] needs to be added to your final app .csproj as shown here.

In your particular case it seems that you are missing MobiiiSDK.framework from your bundle.

Hope this helps.
