我有我的联系人对象：

struct Contact: Codable, Identifiable {
    var id: Int = 0
    var name: String

        Contact(id: 2, name: "Name 2", lastName: "Last Name 2", phoneNumber: "623456789"),
        Contact(id: 3, name: "Name 3", lastName: "Last Name 3", phoneNumber: "633456789"), …

I want to share the view model because i have a fragment with a viewpager with 2 fragments that need to observe data of the parent fragment view model

I used this before to …
