Cannot convert value of type NSAttributedString.DocumentAttributeKey to .DocumentReadingOptionKey

Question

I found this string extension somewhere on SO that allows me to turn html code into an attributed string:

func html2AttributedString() -> NSAttributedStri         


        

Answer 1

Swift 4.x & 5.x

if let rtfPath = Bundle.main.url(forResource: "FileName", withExtension: "rtf") {
        do {
            let attributedString: NSAttributedString = try NSAttributedString(url: rtfPath, options: [NSAttributedString.DocumentReadingOptionKey.documentType: NSAttributedString.DocumentType.rtf], documentAttributes: nil)
            debugPrint(attributedString)
        } catch {
            print("Error while reading the file - \(error.localizedDescription)")
        }
 }

Getting NSAttributedString from file will be changed in Swift 3.x which is as below:

let attributedStringWithRtf: NSAttributedString = try NSAttributedString(url: rtfPath, options: [NSDocumentTypeDocumentAttribute:NSRTFTextDocumentType], documentAttributes: nil)

all the other code same as Swift 4.x & 5.x.
