How to change return type based on a function input which is a class name?
I have multiple data classes and each class has a corresponding class containing more info. I want to write a function in which I should be able to pass an identifier (table name corresponding to the data class). Based on this identifier, object of the corresponding class should be made, the value changed and this object should be returned as output of the function. I have written a simplified version of it on playground but I am unable to get it to work. Any help is appreciated.
