fatal error: unexpectedly found nil while unwrapping an Optional value while receiving image data from NSStream swift

Question

I am sending a message to NSOutputStream to get image data as a payload in http response.

let bufferSize = 999999

case NSStreamEvent.HasBytesAvailable:

        if (inputStream == aStream) {
            var buffer = [UInt8](count: bufferSize, repeatedValue: 0)

            var out: NSString = ""
            while (self.inputStream!.hasBytesAvailable){
                var bytesRead: Int! = inputStream!.read(&buffer, maxLength: buffer.count)
                if bytesRead >= 0 {

                    out = out.stringByAppendingString(NSString(bytes: buffer, length: bytesRead, encoding: encoding)! as String)


                    status = true
                } else {
                    println("# error")
                }
                println("> \(_data) ------- \n \(out)")
            }
        }

In this line of code i am getting fatal error

out = out.stringByAppendingString(NSString(bytes: buffer, length: bytesRead, encoding: encoding)! as String)

Expected result ::

HTTP/1.1 200 OK\r\nContent-Length: 154837\r\nContent-Type: text/html\r\n\r\nIMAGE_DATA

How can i get that IMAGE DATA..

In the `if` statement did you mean `if let inputStream = aStream`? — Vasil Garov, May 05 '15 at 15:34
@flashadvanced : No, inputStream is NSInputStream... like this var inputStream : NSInputStream? — iosLearner, May 05 '15 at 15:37
I think your `inputStream` is nil. Put a break point and check this. — Vasil Garov, May 05 '15 at 16:12
@flashadvanced: No inputStream was not nil, i am getting bytesRead value also [878715] — iosLearner, May 06 '15 at 07:06
