A simple combine sample. Good code? Could it be better?

@Published var input = ""

Watch Development Question
View md
**** Hokay ****
I have an existing project, which includes a Watch App. The main App and the Watch extension share some code.
Now (for reasons I will gladly explain but I ask you so simply presume as valid for now) some code is moving into a framework.
The shared code in the App and in the Extension is depending on (i.e. using) the code in the Framework.
Said Framework should be different for the App and the Watch (i.e. it must show different behavior), this is why don't want to build a universal Framework (I don't even know if that is possible). For simplicity however, the Pricipal Class of both Frameworks should be the same, so that the shared code in the App and the Watch can access the Framework the same way.
