The easiest workaround is create dummy labels in IB, give them the text the color you like and set to hidden. You can then reference this color in your code to set your label to the desired color.

yourLabel.textColor = hiddenLabel.textColor

The only way I could change the text color programmatically was by using the standard colors, UIColor.white, UIColor.green...

The text field placeholder and the  is really  label is hard to see at night  So i change their color depending one what time of day it is    Also make sure you connect the new IBOutlet isReallyLabel  To do so open Main storybaord and control-drag from  Convert  view controller to the  is really  text field and select the isReallyLabel under Outlets   WARNING  I have not tested to see if the application is open while the time of day swaps    x000D   x000D   IBOutlet var isReallyLabel  UILabel   x000D     x000D  override func viewWillAppear animated  Bool    x000D   let calendar   NSCalendar currentCalendar   x000D   let hour   calendar component  Hour  fromDate  NSDate    x000D     x000D   let lightColor   UIColor init red  0 961  green  0 957  blue  0945  alpha  1  x000D   let darkColor   UIColor init red  0 184  green  0 184   blue  0 188  alpha  1  x000D   x000D     x000D   switch hour   x000D   case 8   18  x000D    isReallyLabel textColor   UIColor blackColor   x000D    view backgroundColor   lightColor x000D   default  x000D    let string   NSAttributedString string   Value   attributes   NSForegroundColorAttributeName  UIColor whiteColor     x000D    textField attributedPlaceholder   string x000D    isReallyLabel textColor   UIColor whiteColor   x000D    view backgroundColor   darkColor x000D     x000D    x000D   x000D   x000D

To change the text colour of UILable at runtime use NSAttributedText and do not set UILable textColor    let font   UIFont name   SFProText-Semibold   size  16   if let messageToDisplay   currentUser  lastMessage        let attributedString   NSAttributedString string  messageToDisplay  attributes   NSAttributedString Key font  font  NSAttributedString Key foregroundColor  UIColor named   charcoal          lastMessageLabel attributedText   attributedString   else       let attributedString   NSAttributedString string   Start a conversation   attributes   NSAttributedString Key font  font  NSAttributedString Key foregroundColor  UIColor named   ocean          lastMessageLabel attributedText   attributedString     Note charcoal and ocean are colours defined in Assets xcassets  Resultant Label Images     Above code worked well for me in Xcode 10 2 1 and Swift 5

I don t know why but to change the text color of the labels you need to divide the value you want with 255  because it works only until 1 0   For example a dark blue color    label textColor   UIColor red  0 0  green  0 004  blue  0 502  alpha  1 0

I think most people want their placeholder text to be in grey and appear only once  so this is what I did    Set your color in viewDidLoad    not in IB   commentsTextView textColor   UIColor darkGray  Implement UITextViewDelegate to your controller add function to your controller  func textViewDidBeginEditing   textView  UITextView        if  commentsTextView textColor    UIColor darkGray           commentsTextView text             commentsTextView textColor   UIColor black            This solution is simple
