SwuiftUI check mark single row - arrays

Question

on my project in SwiftUi I'm listing some data in a form, I want to give the user the ability to select a single item in the list with the tap action( can not select more than one in the list)
on the code below I have create a list:
List {
ForEach(listOfCycle, id: \.self) {db in
dbList(db: db, ciclo: self.$cycleSelected)
}
}
and for each row I have the view dbList
import SwiftUI
struct dbList: View {
#State var db : Cycle
#Binding var ciclo : Cycle?
#State var cicloSelected : Bool = false
var body: some View {
HStack{
Text("Database:")
Spacer()
Text(db.idDatabaseAirports ?? "").foregroundColor(self.cicloSelected ? .green: .black).font(self.cicloSelected ? .title : .body)
if self.cicloSelected {
Image(systemName: "checkmark.circle")
}
}.onTapGesture {
self.cicloSelected.toggle()
self.ciclo = self.db
}
}
}
the logic work but the user can tap on multiple row and select more than one, on my project I have to put the checkmark only on one row at the time can't be more than one.
is there any way I can put to avoid multiple selection.
Thanks a lot

The provided code is not testable, so only idea (scratchy, but should be clear).
Note: make sure that Cycle is Equatable
struct dbList: View {
#State var db : Cycle
#Binding var ciclo : Cycle?
var body: some View {
HStack{
Text("Database:")
Spacer()
Text(db.idDatabaseAirports ?? "").foregroundColor(self.db == self.cyclo ? .green: .black).font(self.cicloSelected ? .title : .body)
if self.db == self.cyclo {
Image(systemName: "checkmark.circle")
}
}.onTapGesture {
self.ciclo = self.db
}
}
}
