iOS Swift Enums and Structs Enums Review Enums

I don't believe this is an invalid declaration: enum genre { case drama, romance, satire, tragedy, comedy }

It seems this is just an example of not following best coding practises. It works fine in Xcode, therefore must be a valid declaration. Right?

Hi Antony,

The code you have is a valid declaration but coding standards in Swift say enum's must start with an uppercase letter for both the name and values excluding functions contained within the enum.

// Incorrect
enum genre { 
    case drama, romance, satire, tragedy, comedy 
}

// Incorrect
enum Genre { 
    case drama, romance, satire, tragedy, comedy 
}

// Incorrect
enum genre { 
    case Drama, Romance, Satire, Tragedy, Comedy 
}

// Correct
enum Genre { 
    case Drama, Romance, Satire, Tragedy, Comedy 
}

Hope that helps.

Great, you're right. I raised this because the test at the end of the course asked me to select a valid option, and this was an example of an invalid option. I agree it doesn't follow coding standards, but it's not wrong! :)
