#pragma mark in Swift?
You can use // MARK:
There has also been discussion that liberal use of class extensions might be a better practice anyway. Since extensions can implement protocols, you can e.g. put all of your table view delegate methods in an extension and group your code at a more semantic level than #pragma mark
is capable of.
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
