Question

Hello I have a problem with Swift Protocol

I have declared a protocol named BaseViewModel

I have class called AViewModel and BViewModel which conform to protocol BaseViewModel

class AViewModel : NSObject , BaseViewModel 

class BViewModel : NSObject , BaseViewModel 

Now , I need to declare a completion block that returning those Object which conform to protocol BaseViewModel

typealias ViewModelCompletionBlock = (_ value : BaseViewModel) -> Void
