searchview.swift

// Search view
      HStack {
        HStack {
           //search bar magnifying glass image
           Image(systemName: "magnifyingglass").foregroundColor(.secondary)
                    
           //search bar text field
           TextField("search", text: self.$searchText, onEditingChanged: { isEditing in
           self.showCancelButton = true
           })
           
           // x Button
           Button(action: {
               self.searchText = ""
           }) {
               Image(systemName: "xmark.circle.fill")
                    .foregroundColor(.secondary)
                      .opacity(self.searchText == "" ? 0 : 1)
              }
    }
     .padding(8)
     .background(Color(.secondarySystemBackground))
     .cornerRadius(8)
                
      // Cancel Button
      if self.showCancelButton  {
          Button("Cancel") {
             UIApplication.shared.endEditing(true)
             self.searchText = ""
             self.showCancelButton = false
       }
     }
   }
    .padding([.leading, .trailing,.top])

This searchView is great and works fine. But SwiftUI makes things easy, so you could just add .searchable(text: self.$searchText) below your list to make it native searchable.
