        Hi,

         

        This is my code:

          do{
        
          let options: [NSAttributedString.DocumentReadingOptionKey: Any] = [
          NSAttributedString.DocumentReadingOptionKey.documentType: NSAttributedString.DocumentType.html,
          NSAttributedString.DocumentReadingOptionKey.characterEncoding: String.Encoding.utf8.rawValue]
        
        
          let string = try NSMutableAttributedString(data: data, options: options, documentAttributes: nil)
        
          let attributes: [NSAttributedString.Key: Any] = [.font : labelFont, .foregroundColor : textColor]
          string.addAttributes(attributes, range: NSRange(location: 0, length: string.length))
        
          return string
          }catch{
          return NSAttributedString()
          }
        
        

         

        This is the crash report I got. I believe the problem originates with the creation of the NSMutableAttributedString on line 8 above.

        I am not sure what could have caused this problem, or why the execption wasn't simply caught by my exception handler.
