SwiftUI View instances

does anyone know why when i create an instance of a view by typing it names and then putting parentheses after it, in a for loop, the View shares data amongst the instances? i need unique values within an instance

Here's the code to my view:

struct SwiftUIView: SwiftUI.View {
 
    private let currentDB: [my_Section] = loadDB()
    private let subcurrentDB: [my_subSection] = loadSubsubsections()
    @ObservedObject var first_value: section_array
   // @Binding var current_section: ContentView.my_Section
   // @State private var comment: String = String()
   var body: some SwiftUI.View {
      

       
        Picker(selection: $first_value.first_value, label: Text("Subsection")) {
                                            
            ForEach(0 ..< self.subcurrentDB.count) {
                                                
                                            
                Text(self.subcurrentDB[$0].details)
                                                 
                                                 
       
            }
        }
    }
           
    }

Here's how I create the view...

     ForEach(master_subsections) { result in
                                SwiftUIView(first_value: self.first_value)
                           
                           
                        }
