如何将数据附加到iOS Swift中的nsmutableArray中

我目前正在开发一个食品订购应用程序,当我向任何数组中添加项目时,我需要将这些项目传递给 cartVC 通过 CartDataModal 在哪里 cartArrayDict 是 NSMutableArray 类型。但是当我插入 SelectedDict 应用程序崩溃了,有人能帮我吗?

我的代码是:

var restMenu = [[String:Any]]()

func addTapped(cell: RestaurantItemViewCell)
{
    //get the indexPath for add button click
    let indexPath = self.restTableView.indexPath(for: cell)
     print("the indexPath is", indexPath?.row)

    print("all obj is",restMenu)

    var selectedDict = restMenu[(indexPath?.row)!]
    print("selected dict is",selectedDict)

     selectedDict["ItemQuant"] = cell.itemQuantityLabel.text

    print("selected dict is",selectedDict)


    // Append In Cart Modal
    CartDataModal.shared_Inst.cartArrayDict.insert(selectedDict, at: (indexPath?.row)!)


    print("rest menu is",restMenu)

    restMenu.remove(at: (indexPath?.row)!)
    print("rest menu is",restMenu)

    restMenu.insert(selectedDict, at: (indexPath?.row)!)

    print("restmenu is",restMenu)
}

我的车数据模式:

class CartDataModal: NSObject {
    static let shared_Inst = CartDataModal()
    var cartArrayDict: [String:Any]!
}

从我的视图控制器中,我正在从我的餐馆获取数据。

func moveToDetailController(img:UIImage,name:String)
{
    print("the rest name is", name)

    let pathUrl =  Bundle.main.path(forResource: "ResturantFile", ofType: ".plist")
    print("path url is",pathUrl as Any)

    let finalArray = NSMutableArray(contentsOfFile: pathUrl!)
    print("final Array is",finalArray)

    let restaurantNames = finalArray?.firstObject as? NSDictionary
    print("resturant name is",restaurantNames as Any)


    if let menuDataArray:[[String:Any]] = restaurantNames?.value(forKey: name) as? [[String:Any]]
    {

        print("menu data is",menuDataArray)

    let restVC = self.storyboard?.instantiateViewController(withIdentifier: "RestaurantViewController") as! RestaurantViewController

    restVC.tempImg = img
    restVC.tempTitle = name

    restVC.restMenu = menuDataArray

    self.navigationController?.pushViewController(restVC, animated: true)
    }
}
