Use UITextView instead of UILabel and it has a property to convert your text to hyperlink   Objective-C   yourTextView editable   NO  yourTextView dataDetectorTypes   UIDataDetectorTypeAll    Swift   yourTextView editable   false   yourTextView dataDetectorTypes   UIDataDetectorTypes All    This will detect links automatically   See the documentation for details

If you want this to be handled by UILabel and not UITextView  you can make UILabel subclass  like this one   class LinkedLabel  UILabel    fileprivate let layoutManager   NSLayoutManager   fileprivate let textContainer   NSTextContainer size  CGSize zero  fileprivate var textStorage  NSTextStorage    override init frame aRect CGRect       super init frame  aRect      self initialize      required init  coder aDecoder  NSCoder        super init coder  aDecoder      self initialize      func initialize         let tap   UITapGestureRecognizer target  self  action   selector LinkedLabel handleTapOnLabel       self isUserInteractionEnabled   true     self addGestureRecognizer tap     override var attributedText  NSAttributedString       didSet          if let  attributedText   attributedText              self textStorage   NSTextStorage attributedString   attributedText               self layoutManager addTextContainer self textContainer              self textStorage  addLayoutManager self layoutManager               self textContainer lineFragmentPadding   0 0              self textContainer lineBreakMode   self lineBreakMode              self textContainer maximumNumberOfLines   self numberOfLines                      func handleTapOnLabel tapGesture UITapGestureRecognizer        let locationOfTouchInLabel   tapGesture location in  tapGesture view      let labelSize   tapGesture view  bounds size     let textBoundingBox   self layoutManager usedRect for  self textContainer      let textContainerOffset   CGPoint x    labelSize  width   - textBoundingBox size width    0 5 - textBoundingBox origin x  y    labelSize  height   - textBoundingBox size height    0 5 - textBoundingBox origin y       let locationOfTouchInTextContainer   CGPoint x  locationOfTouchInLabel x - textContainerOffset x  y  locationOfTouchInLabel y - textContainerOffset y      let indexOfCharacter   self layoutManager characterIndex for  locationOfTouchInTextContainer  in  self textContainer  fractionOfDistanceBetweenInsertionPoints  nil        self attributedText  enumerateAttribute NSLinkAttributeName  in  NSMakeRange 0   self attributedText  length     options  NSAttributedString EnumerationOptions rawValue  UInt 0    using            attrs  Any   range  NSRange  stop  UnsafeMutablePointer lt ObjCBool gt   in          if NSLocationInRange indexOfCharacter  range               if let  attrs   attrs                   UIApplication shared openURL URL string   attrs as  String                                         This class was made by reusing code from this answer  In order to make attributed strings check out this answer  And here you can find how to make phone urls

https   github com mattt TTTAttributedLabel  That s definitely what you need  You can also apply attributes for your label  like underline  and apply different colors to it  Just check the instructions for clickable urls   Mainly  you do something like the following   NSRange range    label text rangeOfString   me     label addLinkToURL  NSURL URLWithString   http   github com mattt    withRange range      Embedding a custom link in a substring
