#State Property not accumulating - swift

Question

Users can swipe left or right on a stack of cards to simulate "true" or "false" to a series of quiz questions. I have a #State var called userScore initialized to 0. When dragGesture .onEnded, I compare the "correctAnswer" with the "userAnswer." If they match, add 1 point to the userScore.
The problem: The console prints 1 or 0. The score does not ACCUMULATE.
Please help me calculate the user's final score? Thanks in advance. . .

#State var offset: CGSize = .zero
#State var userScore: Int = 0
#State var userAnswer: Bool = false
private var currentQuestion: Question
private var onRemove: (_ user: Question) -> Void
init(user: Question, onRemove: #escaping (_ user: Question) -> Void) {
self.currentQuestion = user
self.onRemove = onRemove
