我无法通过按钮将项目从一个阵列移动到另一个阵列

Question

所以我是 swift 的新手，我无法让我的愿望清单按钮将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

@objc func wishButtonTapped(_ sender: UIButton) {
    viewModel.sneakers1.append(contentsOf: viewModel.sneakers)
    print("Moved to wishlist")
}

这是我用来让它移动的函数，但是当我运行它时出现这个错误“在调用实例方法'append'时没有完全匹配

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 
  } 
}

这是我用于我的产品的结构
