#pragma mark in Swift?

Up to Xcode 5 the preprocessor directive #pragma mark existed.

From Xcode 6 on, you have to use // MARK:

These preprocessor features allow to bring some structure to the function drop down box of the source code editor.

some examples :

// MARK:

-> will be preceded by a horizontal divider

// MARK: your text goes here

-> puts ‘your text goes here’ in bold in the drop down list

// MARK: - your text goes here

-> puts ‘your text goes here’ in bold in the drop down list, preceded by a horizontal divider

update : added screenshot ’cause some people still seem to have issues with this :
