Creating enumerations to write readable code

Using enumerations is one of the best practices that you should follow while writing any software project and not only iOS projects. Once you find that you have a group of related values in your project, create enum to group these values and to define a safe type for these values. With enumerations, your code becomes more readable and easy to understand, as it makes you define new types in your project that map to other value. In Swift, enumerations have been taken care of and have become more flexible than the ones used in other programming languages.
