SwiftUI Change Observed Object From Another View

I have an observed object in my ContentView which contains tabviews.

class GlobalValue: ObservableObject {
  @Published var stringValue = ""
  @Published var intValue = 0
}

struct ContentView: View {
    @ObservedObject var globalValue = GlobalValue()
}

From one of the tabs I need to change ContentView's observed object value.

ContentView().globalValue.intValue=25

It is not changing the value. How can I change that observed object value? thanks...

It is changing the value. The problem is you are instantiating an instance of GlobalValue locally in your struct. It has no life outside of the struct. I you want to use an Observable Object as a global store like that, you need to create it once and use that instance.

The easiest way to do this is to add static let shared = GlobalValue() in your class, and in your struct use globalValue = GlobalValue.shared which essentially gives you a singleton. You will have one instance that all the views can read and write to.
