23,970 PointsYou do not need to use the word question, you are just asking if the array is empty. Also you need to use the ==
struct Queue<Element> {
var array: [Element] = []
var isEmpty: Bool {
if array.count == 0 {
return true
} else {
return false
}
}
}

Sorry I can't help any further, though - good luck!
