I am completely new to ios , mac and xcode. Basically I am a xamarin developer which is based on .net,at the moment our client have a requirement to use an existing sdk in their xamarin ios project. To create a native binding for xamarin ios,we need to create a .framework file.
So how to create a .framework file from existing SDK Codes,for example lets say this one
https://github.com/facebook/facebook-ios-sdk
This is just an example...I know libraries for Facebook already exists in .Net
