Set Uitextfield Placeholder Color Programmatically

Set UITextField placeholder color programmatically

1 - Create an AttributedString with colour you want.

2 - Set this AttributedString to the textfield attributedPlaceholder property

let placeholder = NSAttributedString(string: "Some", attributes: [NSForegroundColorAttributeName : UIColor.redColor()])
let textField = UITextField(frame: CGRect(x: 0, y: 0, width: 100, height: 30));
textField.attributedPlaceholder = placeholder;
self.view.addSubview(textField)

From apple documentation

var attributedPlaceholder: NSAttributedString!
This property is nil by default. If set, the placeholder string is drawn using a 70% grey color and the remaining style information (except the text color) of the attributed string. Assigning a new value to this property also replaces the value of the placeholder property with the same string data, albeit without any formatting information. Assigning a new value to this property does not affect any other style-related properties of the text field.
