Change of UITextField placeholder color

Question

How to dynamically change placeholder color of the UITextField? This is always the same system color.

No option in xib editor.

Answer 1

This is an improved version of the extension provided by @Medin Piranej above (good idea by the way!). This version avoids an endless cycle if you try to get the placeHolderTextColor and prevents crashes if the color set is nil.

public extension UITextField {

@IBInspectable public var placeholderColor: UIColor? {
    get {
        if let attributedPlaceholder = attributedPlaceholder, attributedPlaceholder.length > 0 {
            var attributes = attributedPlaceholder.attributes(at: 0,
                                                              longestEffectiveRange: nil,
                                                              in: NSRange(location: 0, length: attributedPlaceholder.length))
            return attributes[NSForegroundColorAttributeName] as? UIColor
        }
        return nil
    }
    set {
        if let placeholderColor = newValue {
            attributedPlaceholder = NSAttributedString(string: placeholder ?? "",
                                                       attributes:[NSForegroundColorAttributeName: placeholderColor])
        } else {
            // The placeholder string is drawn using a system-defined color.
            attributedPlaceholder = NSAttributedString(string: placeholder ?? "")
        }
    }
}

}
