How can I retrieve local files with NSURL?

I'm here with a question that probably has a really simple answer that I am overlooking... how can I retrieve local files with NSURL? I have this here:

override func viewDidLoad() {
super.viewDidLoad()
var urlpath = NSBundle.mainBundle().pathForResource("bpreg", ofType: "xml")
let url:NSURL = NSURL(string: urlpath!)!
parser = NSXMLParser(contentsOfURL: url)!
parser.delegate = self
parser.parse()
}


But after it successfully builds it hangs on var urlpath. I've searched around and tried a few suggestions here and other places to no avail. Please help? :(

Answer

You are trying to load a file from your file system, not from web.

For creating the NSURL you need to use fileURLWithPath: class method.

Change your method like:

Swift 2

override func viewDidLoad()
{
    super.viewDidLoad()
    var urlpath     = NSBundle.mainBundle().pathForResource("bpreg", ofType: "xml")
    let url:NSURL   = NSURL.fileURLWithPath(urlpath!)!
    parser          = NSXMLParser(contentsOfURL: url)!
    parser.delegate = self
    parser.parse()
}

Swift 3

override func viewDidLoad()
{
    super.viewDidLoad()
    let urlpath     = Bundle.main.path(forResource: "bpreg", ofType: "xml")
    let url         = NSURL.fileURL(withPath: urlpath!)
    parser          = XMLParser(contentsOf: url)!
    parser.delegate = self
    parser.parse()
}
