load rtf file in UItextView

RTF In textView

    NSURL *rtfPath = [[NSBundle mainBundle] URLForResource: @"description_ar" withExtension:@"rtf"];
    NSAttributedString *attributedStringWithRtf = [[NSAttributedString alloc]   initWithFileURL:rtfPath options:@{NSDocumentTypeDocumentAttribute:NSRTFTextDocumentType} documentAttributes:nil error:nil];
    self.textView.attributedText=attributedStringWithRtf;

I get the following error for the above swift code:

Type of expression is ambiguous without more context

Updated Swift version:

if let rtfPath = NSBundle.mainBundle().URLForResource("filename", withExtension: "rtf") {
    do {
        let attributedStringWithRtf = try NSAttributedString(URL: rtfPath, options: [NSDocumentTypeDocumentAttribute:NSRTFTextDocumentType], documentAttributes: nil)
        textView.attributedText = attributedStringWithRtf
    } catch {
        print("No rtf content found!")
    }
}

Updates for Swift 3.0

if let rtfPath = Bundle.main.url(forResource: "filename", withExtension: "rtf") {
    do {
        let attributedStringWithRtf = try NSAttributedString(url: rtfPath, options: [NSDocumentTypeDocumentAttribute:NSRTFTextDocumentType], documentAttributes: nil)
        textView.attributedText = attributedStringWithRtf
    } catch {
        print("No rtf content found!")
    }
}

Good code. worked for me but I am unable to save images with NSTextAttachment. Please help.

Thanks
