If I have a repository class using Observable macro like this:
Observable
@Observable class TaskRepository {
var number: Int = 0
var isCompleted: Bool = false
}

@Observable class TaskRepository {
var number: Int = 0
var isCompleted: Bool = false
}

And I want to access the repository inside my view model:
Which also use an @Observable here because I want SwiftUI to redraw the view whenever something is updated...
@Observable
// with @State
@Observable class CardViewModel{
@State private var taskRepository = TaskRepository()

var title: String = "Name"
// view model do some processing...
}

// with @State
@Observable class CardViewModel{
@State private var taskRepository = TaskRepository()

var title: String = "Name"
// view model do some processing...
}

Should I use @State to initialize the repository?
because I can do this as well:
@State
// without @State
@Observable class CardViewModel{
private var taskRepository = TaskRepository()

var title: String = "Name"
// view model do some processing...
}

// without @State
@Observable class CardViewModel{
private var taskRepository = TaskRepository()

var title: String = "Name"
// view model do some processing...
}

Can anyone help me understand when I should consider @State? My understanding is by using @State it allows me to inject the TaskRepository into an environment, which is nice to share the data between views.
@State
@State
