Just try this:

print(responseString!)

Try this for your label:

self.lbl1.text = responseString!

This should remove the optional...

The immutable responseString is an optional, so you need to unwrap it to get rid of the Optional(...) wrapping.

You can do this e.g. using the nil coalescing operator

print(responseString ?? "") // Prints "" if responseString == nil
self.lbl1.text = String(responseString ?? "")

or optional binding

if let responseString = NSString(data: data!, encoding: NSUTF8StringEncoding) {
    print(responseString)
    self.lbl1.text = String(responseString)
}
