Unable to update tableviewcel

Answer 1

make sure you reload tableview in main queue in with parameter closure.

ref.child("drivers").child("RideRequests").observe(FIRDataEventType.value, with: { snapshot in
    self.rideRequests.removeAll()
    for item in snapshot.children{
        self.rideRequests.append(item as! FIRDataSnapshot)
    }
    self.rideRequests.reverse()
    DispatchQueue.main.async (execute: { () -> Void in
        self.tableView.reloadData()
    })
})
