您必须在 try catch 中使用此代码，如下所示。

if let rtf = NSBundle.mainBundle().URLForResource("rtfdoc", withExtension: "rtf") {
    do {
        let attributedString = try NSAttributedString(fileURL: rtf, options: [NSDocumentTypeDocumentAttribute:NSRTFTextDocumentType], documentAttributes: nil)
        textView.attributedText = attributedString
        textView.editable = false
        print(attributedString)
    } catch let error as NSError {
        print(error.localizedDescription)
    }
}
