I have simple app, when I run my project it work, but then throw error after running like "Thread 1: Fatal error: No ObservableObject of type msgDatas found. A View.environmentObject(_:) for msgDatas may be missing as an ancestor of this view." struct Home: View {   @EnvironmentObject var data : msgDatas       var body : some View{           ZStack{               Color("bg").edgesIgnoringSafeArea(.top)               NavigationLink(destination: Message(), isActive: $data.show) {                 Text("")       }       VStack{                   topView()       }     }   } }

It throw fatal error for data in "  self.data.selectedData = i", even I try to calling @State for solve, but nothing change. Main: struct Main : View {       @EnvironmentObject var data : msgDatas   @State var show: Bool = false       var body : some View{           List(msgs){i in               cellView(pic: i.pic, name: i.name, msg: i.msg, time: i.time, msgs: i.msgs).onTapGesture {                   self.data.selectedData = i         self.show.toggle()       }     }   } } cellView: struct cellView : View {       var pic : String   var name : String   var msg : String   var time : String   var msgs : String       var body : some View{           HStack(spacing: 15){               Image(pic).resizable().frame(width: 50, height: 50).clipShape(Circle())               VStack(alignment:.leading,spacing: 5){                   Text(name)         Text(msg).lineLimit(2)       }               Spacer()               VStack(spacing: 10){                   Text(time)         if msgs != ""{                       Text(msgs).padding(8).background(Color("bg")).foregroundColor(.white).clipShape(Circle())         }         else{                       Spacer()         }       }             }.padding(9)   } }

I have a simple SwiftUI project, when I click the any list items, I want to route different SwiftUI.
