Reading a RTF file and parse plaintext

I am doing this to get the content of a file using NSOpenPanel, but I am getting a lot of weird stuff returned from the .rtf file I select.

My panel code:

  • How to print out the method name and line number and conditionally disable NSLog?
  • How to create NSCollectionView programmatically from scratch?
  • NSAttributedString initWithData and NSHTMLTextDocumentType crash if not on main thread
  • IBOutletCollections and Interface Builder on OSX
  • What is a non-fragile ABI?
  • What's the right way to parse an ISO8601 date in cocoa?
  • var panel: NSOpenPanel = NSOpenPanel()
    var fileTypesArray: NSArray = ["txt", "rtf", "nil"]
    panel.canChooseFiles = true
    panel.allowedFileTypes = fileTypesArray as [AnyObject]
    panel.allowsMultipleSelection = false
    if panel.runModal() == NSModalResponseOK {
        var url = panel.URL!.path
        let path = url
        let expandedPath = path!.stringByExpandingTildeInPath
        let data: NSData? = NSData(contentsOfFile: expandedPath)
        if let fileData = data {
            let content = NSString(data: fileData, encoding:NSUTF8StringEncoding) as! String

    The contents of my .rtf document is “Testing 123”

    This is what is being printed to the console:

    {\fonttbl\f0\fswiss\fcharset0 Helvetica;}
    \f0\fs24 \cf0 Testing 123\

    Is there any way I can get just the text from the file, and what is all the other stuff that is being printed?

    That “other stuff” is the actual RTF data.

    I would recommend using the NSAttributedString initializer NSAttributedString(path:documentAttributes:), which will read in and process the RTF data. Then you can access the plain text by using attributedString.string.

    In your case, it would be

    if let content = NSAttributedString(path: expandedPath, documentAttributes: nil) {
        // do something with content or content.string
