guard statement variable do not give me value

var country = ""
 if placemark.country != nil{
      country = placemark.country!
  }
 self.awareLocationDetaile.text = country

Try to convert this code guard statement 

guard let country = placemark.country else{                        
     return    
 }
self.awareLocationDetaile.text = country

but unfortunate country have no value if i use guard statement where if give me value . what am i missing ?

UPDATE :

        CLGeocoder().reverseGeocodeLocation(location) { ( clPlacemark :[CLPlacemark]?,error : NSError?) in
            if error != nil {
               print(error)
            }else{
                if let placemark = clPlacemark?[0]{
                 // print(placemark)
                    //MARK:- we are a good programmer
//                    var country = ""
//                    if placemark.country != nil{
//                        country = placemark.country!
//                    }
//                  self.awareLocationDetaile.text = country


                    guard let country = placemark.country else{

                        return

                    }


                    self.awareLocationDetaile.text = country
                }

            }
        }

The guard statement works exactly as it is supposed to work. You are not missing anything. It does what it is supposed to do, not what you want. Your first code sample can be written a lot easier as 

self.awareLocationDetaile.text = placemark.country ?? ""

It seems you copied a comment that the queen wrote after she wrote her very first line of code at the age of 89. Note the royal "we": 

//MARK:- we are a good programmer

On the other hand, the return statement inside the guard statement will return from the closure, so nothing after that will be executed.
