NSData: unexpectedly found nil while unwrapping an Optional value

Question

It may be the basic swift quetion, But i am new to swift or iOS development. I am getting the error fatal error: unexpectedly found nil while unwrapping an Optional value<

Answer 1

You declared nilObj as optional and initialised it with nil. Then in your else clause you are trying to unwrap that. For fixing the issue you just need to remove that !

Change your code to:

func Call() -> NSData?
{        
     let nilObj: NSData? = nil 
     if(false)
     {  
        // Doing something     
     }
     else
     {         
         return nilObj       
     } 
}
