var body: some View {

   List {

       ForEach(self.people) { person in

           ProfileView(person)

   }
   .animation(.default)
}

    Declaration

    Swift

    public init<O: DynamicObject>(
    _ objectSnapshots: Data,
    @ViewBuilder content: @escaping (ObjectSnapshot<O>) -> Content
) where Data.Element == ObjectSnapshot<O>, ID == O.ObjectID

    Parameters

    objectSnapshots

var body: some View {

   List {

       ForEach(sectionIn: self.people) { section in

           Section(header: Text(section.sectionID)) {

               ForEach(objectIn: section) { person in

                   ProfileView(person)
               }
           }
       }
   }
   .animation(.default)
}

    Declaration
