Can someone please help me understand PassthroughSubject and CurrentValueSubject? What I understand so far is that they are subjects where subscribers can listen to changes made to these subjects, but I'm really straggling to understand the following.
I'm I correct by saying that PassthroughSubject or CurrentValueSubject could replace delegation and asynchronous function calls?
Is it possible to delare a subject in Class A and subscribe to listen to those subject changes in Class B and in some other classes or are listeners meant to only be used direclty in SwiftUI structs?
Thanks
