如何将字符串转换为 Int？ Swift

Question

我有这段代码，所以我需要如何将 spentBudget 转换为 Int？

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    
    let cell = tableView.dequeueReusableCell(withIdentifier: "eventCell", for: indexPath) as! BudgetTableViewCell
    
    let budgetEvent: BudgetModel
    budgetEvent = budgetList[indexPath.row]
  
    cell.nameEventLabel.text = budgetEvent.eventName
    
    if let spent = budgetEvent.spentBudget{
        cell.spentBudgetLabel.text = spent
   }else{
        print("spent budget is empty")
    }
    
    let totalSpent = budgetList.compactMap{ [=11=].spentBudget }.reduce(0, +)
    self.spentBudget.text = String("$ \(totalSpent)")
    print("sum \(totalSpent)")
    return cell
}'''

String to int returns 可选。例如：

let myInt2 = Int(myString) ?? 0

以您为例，它将是：

let spentBudgetInt = Int(spentBudget) ?? 0
