works in Xcode but not on the website

the code I have here works perfectly fine in Xcode but the website gives me "the code cannot be compiled", however the editor isn't showing any errors. Any ideas?

generics.swift
struct Queue<Element> {
    var array: [Element] = []
    var isEmpty: Bool {
        if array.count == 0 {return true}
        else {return false}
    }
    var count: Int {
        return array.count
    }
    mutating func enqueue(element: Element) {
        array.append(element)
    }
}

You are close on this one see below code and let me know if you understand from my example

struct Queue<Element> {

    var array: [Element] = []


    var isEmpty: Bool {
        if array.count == 0 {
            return true
        } else {
            return false
        }
    }

    var count: Int {
        return array.count
    }

    public mutating func enqueue(_ element: Element){
        array.append(element)
    }

}
