        Function Keys

        Function Keys

        This book describes the four essential keys to unlock the secret of software design. The four keys are:

        • A function name should tell a story
        • A function should be easy to read and understand
        • A function should be easy to maintain
        • A function should be easy to test


        This book is for you if you want to:

        • properly evaluate your app to find classes and functions to improve.
        • understand why your current code needs to be refactored.
        • refactor your code into small pieces of unit-testable classes and functions
        • find an architecture agnostic approach to writing good code.
        • go outside Clean Swift’s VIP cycle and design your own workers and custom views.
        • come up with good test cases to fully cover all code paths.
        • write non-fragile and maintainable unit tests.
        • make sure you’re doing the right thing before you start refactoring.
        • avoid having to refactor after refactor, again and again.
