My advice is to keep methods in view controller. What you’re doing is called Single Responsibility principle.īy moving methods from view controller to separate class, you’re breaking that principle, because even if it looks like one class now it will not be one class in the future, when in turn you’ll want to update your design to add new features and methods. Is this a good approach, or is there a better way to structure my class files? This allows me to create an instance of the class, execute the SQL, and return the results to my viewcontroller for display. I have a ‘SqlDataProvider’ class file which contains several SQL statements and methods to use these statements. I wish to make my unit tests faster, and to be more testable, for this, I have moved the methods that I use to manipulate and interact with the database to be stored in a separate class file from my viewcontroller’s class file. I have a database that I wish to extract information from, and display it in a table view.
