Error is straight forward and its because of wrong placeholders you have used in function call. Inside init you are not passing any parameters to your function. It should be this way

destination = Node("some key", neighbors: [edge1 , edge2], visited: true, lat: 23.45, long: 45.67) // fill up with your dummy values

destination = Node()

Add empty initialiser in your Node class

init() {
