   }]
}]

Now i want to show this response on text view as it is and here is my code 

self.tv_response.text = String(format:"%@", JSON as! String )

but getting an error

Could not cast value of type '__NSCFArray' (0x1025a8ae0) to 'NSString' (0x101c13b20).

I also try 

self.tv_response.text = NSString(format:"%@", JSON as! String )

but not working please help me ...

NSString(format:"%@", JSON as! String )

here JSON file in not String file its an Array. You are unwrapping it(!).So use 

String(format:"%@", JSON)

or else 

self.tv_response.text = "\(JSON)"

You shouldn't be using String(format:_:) in Swift anyways. A better way to do it would be self.tv_response.text = "\(JSON)". This uses String Interpolation which lets you conveniently create a string out of any type of value.

However, if you must do it with String(format:_:), you can do the following: self.tv_response.text = String(format:"%@", JSON).

Your response is array so you can not directly convert it to string.

self.tv_response.text = "\(JSON as! NSArray)"

or 

self.tv_response.text = "\(JSON as! [[String: AnyObject]])"
