I think there are the answers who helped you out. The correct way to do this is:

yourLabelName.textAlignment = NSTextAlignmentCenter;


for more documentation you can read this:
https://developer.apple.com/documentation/uikit/uilabel

Here you are,

yourLabel.textAlignment = UITextAlignmentCenter


EDIT

if you target above iOS6 use NSTextAlignmentCenter as UITextAlignmentCenter is depreciated

NSTextAlignmentCenter

UITextAlignmentCenter

Hope it helps.

This has changed as of iOS 6.0, UITextAlignment has been deprecated. The correct way to do this now is:

yourLabel.textAlignment = NSTextAlignmentCenter;


Here is the NSTextAlignment enumerable that gives the options for text alignment:

Objective-C:

enum {
NSTextAlignmentLeft = 0,
NSTextAlignmentCenter = 1,
NSTextAlignmentRight = 2,
NSTextAlignmentJustified = 3,
NSTextAlignmentNatural = 4,
};
typedef NSInteger NSTextAlignment;


Swift:

enum NSTextAlignment : Int {
case Left
case Center
case Right
case Justified
case Natural
}


Source

label.textAlignment = NSTextAlignmentCenter;


see UILabel documentation

If you have a multiline UILabel you should use a NSMutableParagraphStyle

yourLabelName.numberOfLines = 0
let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.alignment = .Center

let attributes : [String : AnyObject] = [NSFontAttributeName : UIFont(name: "HelveticaNeue", size: 15)!, NSParagraphStyleAttributeName: paragraphStyle]

let attributedText = NSAttributedString.init(string: subTitleText, attributes: attributes)
yourLabelName.attributedText = attributedText


In Swift 3 and beyond it should be

yourlabel.textAlignment = NSTextAlignment.center


in swift 4:

let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.alignment = NSTextAlignment.center

// in Swift 4.2
let attributedString = NSMutableAttributedString(string: "Your String", attributes:[NSAttributedString.Key.paragraphStyle:paragraphStyle])

// in Swift 4.1--
let attributedString = NSMutableAttributedString(string: "Your String", attributes: [NSAttributedStringKey.paragraphStyle:paragraphStyle])

let yourLabel = UILabel()
yourLabel.attributedText = attributedString


Yourlabel.textAlignment = UITextAlignmentCenter;


UITextAlignmentCenter

NSTextAlignmentCenter
