The following function in your code does not do anything.

mutating func enqueue(element: Element) {

}

It should append the Generic to your array.

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

Thanks Chris, I was not omitting external parameter of enqueue func, that's why my code snipped was not getting compiled itself. After omitting external param as you mentioned in your code snipped, I am able to compile the program now. Good catch. Thanks for your help.
