Converting PathForResource To String Returning nil Swift

When loading a local resource file in a mac app 

let urlpath = NSBundle.mainBundle().pathForResource("myResource", ofType: "html");

Converting the resource path to a string for NSURL always returns nil

    println("resource path = \(urlpath)") <---resource logged ok

    web.frameLoadDelegate = self;
    let requesturl = NSURL(string: urlpath!)

   println("URL String  = \(requesturl)"),<---- returns nil

    let request = NSURLRequest(URL: requesturl!)
    web.mainFrame.loadRequest(request)

Which presumably is why im getting the error found nil while unwrapping an Optional value What am I missing here to correctly convert the pathForResource to a string?

For Swift 5

let path = Bundle.main.path(forResource: "myResource", ofType: "html")
let url = URL(fileURLWithPath: path!)

The code given in Leonardo's answer should work and is the easier and safer method with optional binding. Here is an explanation why your code fails:

let requesturl = NSURL(string: urlpath!)

returns nil because urlpath is a file path and not an URL string (such as "file:///path/to/file").

If you replace that line with

let requesturl = NSURL(fileURLWithPath: urlpath!)

then you will get the expected output.

if let myFileUrl = NSBundle.mainBundle().URLForResource("yourFile", withExtension: "html"){
            // do whatever with your url
}
