I tried to complete this code challenge but I can't pass Task 4. I write my code in xcode and than copy it in the editor. My code works in a playground but the editor doesn't accept it. Am I missing something? Is there something more to the task that I didn't notice?
struct Queue<Element> {
var array: [Element] = [Element]()
var isEmpty: Bool {
if array.count == 0 {
return true
} else {
return false
}
}
var count: Int {
var counter = 0
for _ in array {
counter += 1
}
return counter
}
mutating func enqueue(element: Element) -> [Element] {
self.array.append(element)
return array
}
}

mutating func enqueue(_ element: Element) -> [Element] { // Be sure to omit it with _
self.array.append(element)
return array
}
