Swift Error: Editor placeholder in source file
<p>Hello I am implementing a graph data structure. When I try to build the application the I get the error "Editor placeholder in source file"</p>

<p>The full graph implementation was pulled from WayneBishop's GitHub from here <a href="https://github.com/waynewbishop/SwiftStructures" rel="noreferrer">https://github.com/waynewbishop/SwiftStructures</a></p>

<pre><code>class Path {

var total: Int!
var destination: Node
var previous: Path!

init(){
    //Error happens on next line
    destination = Node(key: String?, neighbors: [Edge!], visited: Bool, lat: Double, long: Double)
     }
}
</code></pre>

<p>I changed the <code>Node</code> Class around to:</p>

<pre><code>public class Node{

var key: String?
var neighbors: [Edge!]
var visited: Bool = false
var lat: Double
var long: Double

init(key: String?, neighbors: [Edge!], visited: Bool, lat: Double, long: Double) {
    self.neighbors = [Edge!]()
     }

}
</code></pre>

<p>This Error happens 5 times throughout the code that I have built so far. Also this question has been asked, but not answered.</p>

<p>I think the error may be due to my changes to the <code>init()</code> in the <code>Node</code> class. Prior to my changes it was just <code>init()</code>. If it is, how can I add objects to the class? Pardon me if I am not correct in my programming terminology, as I am relatively new to OOP.</p>
