How to check if UILabel has attributedText or normal text programmatically?

Question

Is there any way to tell if UILabel has its text set using label.attributedText or label.text property?

The problem is when you set attributedText, text is also updated and vice versa, so it is not possible to check these properties for nil.

Inspired by @lukas-o I have written an extension on UILabel that determines if it contains an attributedText or not. In fact if the NSAttributedString does not contain any attributes, this computed property will evaluate it to not be attributed.

extension UILabel {
    var isAttributed: Bool {
        guard let attributedText = attributedText else { return false }
        let range = NSMakeRange(0, attributedText.length)
        var allAttributes = [Dictionary<String, Any>]()
        attributedText.enumerateAttributes(in: range, options: []) { attributes, _, _ in
            allAttributes.append(attributes)
        }
        return allAttributes.count > 1
    }
}
