所以我是Swift的新手，我很难让我的愿望列表按钮将一个项目从阵列运动鞋移动到阵列运动鞋1

class Sneakers {
    var sneakers = [
        BagProducts(image: UIImage(named: "Image")! , category: "Men" , name: "Adidas Gazelle", price: 100.00, size: "40" , color: "Blue"),
        BagProducts(image: UIImage(named: "Image")! , category: "Men" , name: "Adidas Gazelle", price: 100.00, size: "40" , color: "Blue"),
    ]
    
    var sneakers1 = [
        WishProducts(image: UIImage(named: "AdidasGalaxy")! , category: "Women" , name: "Adidas Galaxy 6", price: 55.00, size: "", color: ""),
        WishProducts(image: UIImage(named: "NewBalance")! , category: "Men" , name: "New Balance BB550", price: 150.00, size: "", color: ""),
    ]
}

这是我的数组
按钮应该一次只移动一个单元格

@objc func wishButtonTapped(_ sender: UIButton) { 
    print("ola- \(viewModel.sneakers1)") 

    for sneaker in viewModel.sneakers { 
        let wishProduct = WishProducts(image: sneaker.image, category: sneaker.category, name: sneaker.name, price: sneaker.price, size: sneaker.size, color: sneaker.color) 
        viewModel.sneakers1.append(wishProduct) 
     } 
   print("ola- \(viewModel.sneakers1)") 
   print("Moved to wishlist") 
}

这是我用来使它移动的函数，但是当我运行它时，它出现了这个错误“在调用示例方法'append'时没有精确匹配”

protocol BagProduct {
   var image: UIImage { get } 
   var category: String { get } 
   var name: String { get } 
   var price: Double { get } 
   var size: String { get } 
   var color: String { get } 
}
protocol WishProduct { 
   var image: UIImage { get } 
   var category: String { get } 
   var name: String { get } 
   var price: Double { get } 
   var size: String { get } 
   var color: String { get } 
}
struct WishProducts: WishProduct { 
   let image: UIImage 
   let category: String 
   let name: String 
   let price: Double 
   let size: String 
   let color: String 

init(image: UIImage, category: String, name: String, price: Double, size: String, color: String) { 
   self.image = image 
   self.category = category 
   self.name = name 
   self.price = price 
   self.size = size 
   self.color = color 
  } 
}

struct BagProducts: BagProduct { 
   let image: UIImage 
   let category: String 
   let name: String 
   let price: Double 
   let size: String 
   let color: String 
init(image: UIImage, category: String, name: String, price: Double, size: String, color: String) { 
   self.image = image 
   self.category = category 
   self.name = name 
   self.price = price 
   self.size = size 
   self.color = color 
  } 
}

这是我在产品中使用的结构体
