type (key:Int, value: Any) does not conform to protocol sequence - Loop through dictionary : I have a dictionary as `[Int: Any]()`

my code:

                    var test = [Int: Any]()
                    
                    test = self.header_all_items[header] as! [Int : Any]
                    
                    for tes in test{
                        
                        for (key:value)in tes{ // error line
                            print(key)
                        }
                        
                    }

I got this error :

    type (key:Int, value: Any) does not conform to protocol sequence
