SWIFT2 + Alamofire3 Upload photo, simple method - swift2

Question

I am trying to upload photo to server with this method from alamo doc
let fileURL = NSBundle.mainBundle().URLForResource("Default", withExtension: "png")
Alamofire.upload(.POST, "https://httpbin.org/post", file: fileURL)
I edit method to my needs like this
let fileURL = NSBundle.mainBundle().URLForResource(filePath, withExtension: "png")
Alamofire.upload(.POST, urlDomain + "api/user/", parameters: parameters, headers: headers, file: fileURL)

This should work for you too!
