Swift Styleguide

Indentation

2 spaces, no tabs.

Code comments & code documentation

If a comment contains documentation or explanation, it must use a triple slash (///), regardless of its position in the source code.

Use double slash comments (//) only for Xcode directive comments ("MARK:", "TODO:", etc.) and for temporarily disabling blocks of code. You must never use double slash (//) for documentation comments.

guard clauses

guard clauses must be written multi-line. If a clause combines multiple conditions, each condition must be on its own line.
