How do I create array conformed to ObservableObject?

Question

class Group: ObservableObject {
    @Published var size: CGFloat = 22
}

struct content: View {
    @ObservedObject var groups: [Group] = []
    var body: some view {
        .
        .
        .
  }
}

above code error message :

Referencing initializer 'init(wrappedValue:)' on 'ObservedObject' requires that '[Group]' conform to 'ObservableObject'

I need array conformed to ObservableObject because i need to detect size property of Group in [Group]

How to make array of ObservableObject(ObservedObject)

Answer 1

I am not sure how to solve this problem directly but one way to solve your problem would be something like a GroupStore which holds your array. That could look like this:

class GroupStore: ObservableObject {

    @Published private(set) var groups: [Group] = []
    .
    .
    .
}

And then in your View you add the GroupStore property like this:

struct content: View {

    @ObservedObject var groupStore: GroupStore
    .
    .
    .
}
