like below fixes the issue 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:
code :
let requesturl = NSURL(string: urlpath!)
let requesturl = NSURL(fileURLWithPath: urlpath!)

fixed the issue. Will look into that further You probably have not checked the box to include that file. What you show is an attempt to fetch the file "abc.mp4" from your bundle.
Look in the target's build phases, and make sure that file is being copied to the bundle.

This might help you There is no simple pathForResource method of NSBundle, there's at least a second parameter e.g. pathForResource:ofType:
Since you need an NSURL anyway, use the URL released API, replace the entire if let expression with
code :
func playVideo() {
  switch videoNumber {
    case 1 : url="20"
    case 2 : url="10"
    default : break
  }

  if let movieUrl = NSBundle.mainBundle().URLForResource(url, withExtension: "mp4") {
     self.avPlayer = AVPlayer(URL: movieUrl)
     self.avPlayerViewControler.player = self.avPlayer
  }
}

To fix the issue you can do I recently converted my app from the previous version of swift to swift 3.0 (and also got the most recent version of Xcode) and, among many other errors, I received the following one: , I believe you can change your code like this:
code :
    PFPush.subscribeToChannel(inBackground: "", block: {(succeeded, error) -> Void in
        if succeeded {
            print("ParseStarterProject successfully subscribed to push notifications on the broadcast channel.\n");
        } else {
            print("ParseStarterProject failed to subscribe to push notifications on the broadcast channel with error = %@.\n", error)
        }
    }

Hope that helps Trying to do something so simple but it's simply not working for me. , Most likely there is an additional space in your data, note:
code :
print(Double("-85.1113644443208")) // => Optional(-85.111364444320799)
print(Double("-85.1113644443208 ")) // => nil
print(Double(" -85.1113644443208")) // => nil
let doubleLong = Double(long.trimmingCharacters(in: CharacterSet.whitespaces))
let numberFormatter = NumberFormatter()
numberFormatter.numberStyle = .decimal
numberFormatter.locale = Locale(identifier: "en_US_POSIX")

print(numberFormatter.number(from: "-85.1113644443208") as Double?) // => Optional(-85.111364444320799)
print(numberFormatter.number(from: " -85.1113644443208") as Double?) // => Optional(-85.111364444320799)
print(numberFormatter.number(from: "-85.1113644443208 ") as Double?) // => Optional(-85.111364444320799)

around this issue I'm using the following code to convert Data to String in swift. The returned String is nil. Could you please help me identify what is going wrong. Thank you. , this base 64 encryptedData by RSAUtils lib so use this
code :
if ( dataObject != nil ) {
         let encryptedDataText = dataObject!.base64EncodedString(options: NSData.Base64EncodingOptions())
        NSLog("Encrypted with pubkey: %@", encryptedDataText)
        }
