#pragma mark in Swift?

Use

// MARK: SectionName

or

// MARK: - SectionName

This will give a line above pragma mark, making it more readable.

For ease just add

// MARK: - <#label#>


to your code snippets.


**Alternate way -**

Use it in this way

private typealias SectionName = ViewController
private extension SectionName {
// Your methods
}

This will not only add mark(just like pragma mark) but also segregate the code nicely.

There are Three options to add `#pragma_mark` in Swift:

1) `// MARK: - your text here -`

2) `// TODO: - your text here -`

3) `// FIXME: - your text here -`

Note: Uses `-` for add separators

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.

You may also be interested in **Swift 4.2 / XCode 10** compiler directives like

#warning("Some string to display")

and

#error("Some error to display")

It might be useful when you really don't want to miss something.

Professional programer must be use this tag for good code.
It is also good for team work.

// MARK: example Web Service start here
// TODO: example 1
// FIXME: Please change BASE url before live

It is easy to find method like this

Try this:

// MARK: Reload TableView

func reloadTableView(){

tableView.reload()
}

Pragma mark is a way to improve the readability of your code. The pragma comments would appear like tags on the Xcode jumpbar.


//MARK: <Your comment goes here>


Example: In the code,

//MARK: Properties

// MARK: View Life cycle

//MARK: Helper methods


This is how it would appear in the Xcode jump bar.

In Xcode 11 they added minimap which can be activated `Editor -> Minimap`.

Minimap will show each mark text for fast orientation in code.
Each mark is written like `// MARK: Variables`

`Pragma mark - [SOME TEXT HERE]` was used in *Objective-C to group several function together* by line separating.

In *Swift* you can achieve this using `MARK, TODO OR FIXME`

i. *MARK :* `//MARK: viewDidLoad`

This will create a *horizontal line* with functions grouped under viewDidLoad(shown in screenshot 1)

ii. *TODO :* `//TODO: - viewDidLoad`

This will group function under *TODO: - viewDidLoad* category (shown in screenshot 2)

[![Screenshot 2][2]][2]

iii. *FIXME :* `//FIXME - viewDidLoad`

This will group function under *FIXME: - viewDidLoad* category (shown in screenshot 3)
