Answer 1

Swift 4

extension String {
    var replacingHTMLEntities: String? {
        do {
            return try NSAttributedString(data: Data(utf8), options: [
                .documentType: NSAttributedString.DocumentType.html,
                .characterEncoding: String.Encoding.utf8.rawValue
            ], documentAttributes: nil).string
        } catch {
            return nil
        }
    }
}

Simple Usage

let clean = "Weeknd ‘King Of The Fall’".replacingHTMLEntities ?? "default value"
