How can I make parts of the source code "folded" (hidden) in Xcode?

Question

In the Visual Basic.Net I can use

#Region "identifier_string" #End Region

to "fold" (hide) parts of the source code in the editor.

How can I do that in Swift ?

@Eric D.'s answer is perfect.

If you want to mark down some regions then you can use it like as :

// 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
