Variables Capitalization

Variables and constants names must be written using:

• lowerCamelCase for variables (i.e. var)
• lowerCamelCase for non-static constants (i.e. let)
• PascalCase for static constants (i.e. static let)

Always be aware of acronyms.

Example

Good

let users: [User]
var selectedUser: User?
static let MaxNumberOfUsersAllowed = 100

Bad

let Users: [User] // NO
var SelectedUser: User? // NO
static let maxNumberOfUsersAllowed // NO!
static let MAX_NUMBER_OF_USERS_ALLOWED // NOOOOOO!!!!!!

Motivation

• Consistency.
• Readability: Variables or non-static constants are easier to be distinguished from static constants.
