Find better way to handle pagination JSON with MVVM in Swift 5 - swift

Question

currently my project uses structure MVVM. I have a Pagination JSON like this:
{
"has_next": false,
"next_params": {
"limit": 10,
"offset": 10
},
"results": [
{ "id": 1, "name": "A Place" },
{ "id": 2, "name": "A Night" }
]
}
This is my ViewModel:
class LifeStoryViewModel: ObservableObject {
#Published var lifes: [Life] = []
var has_next: Bool = true
var next_params: [String:Any] = [:]
var fetching: Bool = false
func fetchLifeStories () {
let url = URL(string: STRINGURL)
URLSession.shared.dataTask(with: url!) { (data, res, err) in
DispatchQueue.main.async {
let vvv = try! JSONDecoder().decode(LifeStories.self, from: data!)
self.lifes = vvv.results
}
}.resume()
}
}
As you guys see, I have a model LifeStories:
struct Life: Identifiable, Codable {
var id: Int
var name: String
var description: String
var thumbnail: String
}
struct LifeStories: Codable {
var has_next: Bool
var results: [Life]
}
Can I remove LifeStories model and handle it inside the LifeStoryViewModel instead? How can I do this because I think LifeStories model is not necessary.

You can use a generic type for paginated responses. Here's an example from the app I'm working on:
struct PaginatedResponse<Element: Codable>: Codable {
var count: Int
var next: String?
var previous: String?
var results: [Element]
}
