Cannot convert value of type 'NSURL' to expected argument type 'NSURLRequest'

For a POST request, I use this code:

private func post(url: String, params: [String: AnyObject], headers: [String: AnyObject]) {

   let url = NSURL(string: apiUrl)!
   let session = NSURLSession.sharedSession()
   let request = NSMutableURLRequest(URL: url)
   request.HTTPMethod = "POST"
   request.setValue("application/json; charset=utf-8", forHTTPHeaderField:  "Content-Type")
   request.addValue("application/json", forHTTPHeaderField: "Application")

   do {
      request.HTTPBody = try NSJSONSerialization.dataWithJSONObject(params, options: NSJSONWritingOptions())
   } catch {            
      print("error")

      //POST with completionHandler
      var task = session.dataTaskWithRequest(url, completionHandler: { (data, response, error) -> Void in        
        print(data)           
      })        
   }
}

and at the line that startst with var task = ... I get this error: Cannot convert value of type 'NSURL' to expected argument type 'NSURLRequest'

change this line:

var task = session.dataTaskWithRequest(url, completionHandler: { (data, response, error) -> Void in

and pass in the request... not the url:

var task = session.dataTaskWithRequest(request, completionHandler: { (data, response, error) -> Void in

Always read the method name you are calling, this is specifically creating a dataTaskWith a REQUEST, xcode should of also highlighted this.
