brace-style

Definitions of - class - struct - function - Control flow constructs (if, else if, else, switch, for, while, repeat-while) - init - protocol - enum - closure - Getters and Setters (set, get) - extension

should follow the One True Brace Style (1TBS): each construct has its opening brace one the same line along with the same indentation level as its header, the statements within the braces are indented, and the closing brace at the end is on the same indentation level as the header of the function at a line of its own. Braces are not omitted for a control statement with only a single statement in its scope. Every opening brace must also have one space preceding it.

function-whitespace

Every function and method declaration should have one blank line before and after itself. An exception to this rule are functions that are declared at the start of a file (only need one blank line after their declaration) or at the end of a file (only need one blank line before their declaration). Comments immediately before a function declaration (no blank lines between them and the function) are considered to be part of the declaration.
