I'm sorry sir, my github account was suspended, I will now open it up pr again.

let cartSaved = UserDefaultsStore<CartItem>(uniqueIdentifier: "cart")

When I add the same product with the same id I want to increment the quantity but the saved cart (::allObject) method return me the same product

  var cart  = getCart()
        
        var targetItem  = cart.first(where: {$0.product.id == cartItem.product.id}) // <-- targetItem is a product in the [CartItem]
                
        
        if targetItem == nil  {
        
            print("prodct added ! ")
            cartItem.quantity += 1
            cart.append(cartItem)
            
            
        }else{
            
            targetItem?.quantity += 1
            
        }
        
        saveCart(cart: cart) // <--- here save again it should save the targetItem += 1

Would it be possible to add support to use iCloud through NSUbiquitousKeyValueStore instead of UserDefault ?

In inspecting the plist files that are created, I was surprised to see that they're not human readable, even though a JSONEncoder is being used. The issue is that you're taking the encoding and storing that directly, rather than converting it to a string.

I think it would be nice to have that at least as an option, to aid in debugging. To do so, you'd change save to look more like:

	public func save(_ object: T) throws {
		let data = try encoder.encode(object)
                if let str = String(data: json, encoding: .utf8) {
		     store.set(str, forKey: key(for: object))
		     increaseCounter()
                } else {
                     // throw appropriate error.
                }
	}

Cannot load package by SPM:
I have used:

".package(url: "https://github.com/omaralbeik/UserDefaultsStore.git", from: "1.4.0")

I have gotten:
`error: dependency graph is unresolvable; found these conflicting requirements:

Dependencies:
https://github.com/omaralbeik/UserDefaultsStore.git @ 1.4.0..<2.0.0`

After porting a bunch of code to work with UserDefaultsStore, I discovered that the "objects" you store can only be structs. It would be good to document this.

Add support to integrate into projects using Swift Package Manager

The project has a 100% test coverage, however codecov is not working for some reason 😭
If you have an idea how to fix it, your help is highly appriciated

Based on the documentation in the readme, I got the impression that a laptop owned by a user came from the laptop store. Meaning that what was serialized to the store was the key to the laptop and that when I retrieved a user, it would also retrieve the laptop from the store.

What's actually happening is that the laptop is serialized into the data for the user. So if I were to say that John owned a MacBook and then changed the description of the MacBook in the laptop store, when I retrieved john's record, I would get the updated Macbook data. Instead, I get whatever was serialized when I saved john to the user store.

Does this make sense? I think it would be good to be explicit about what's happening, because I was getting inconsistency errors based on what I thought the docs were implying.

Looks dangerous.
