TableView with multiple cell swift

I would like to call two cell. as long as chipnumber2 is not empty, I'd like to call cellnew. But " let deviceItem: Device3New = itemsNew[indexPath.row]" line is experiencing problems.This error : fatal error: index out of range. How do I call two cell functions? This error occurs when calling Cellnew, but there is no problem when calling cell. So how do I call two cell functions in a Tableview?

class NewMainTableViewController: UITableViewController, UITextFieldDelegate, MiniTabBarDelegate, NVActivityIndicatorViewable {
    var items: [Device3] = []
        var itemsNew: [Device3New] = []

        let cellId: String = "cellId"

    override func viewDidLoad() {
        super.viewDidLoad()
        tableView.register(DeviceTableViewCell2.self, forCellReuseIdentifier: cellId)

     }

     override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

            return items.count
        }

     override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

            let cell = tableView.dequeueReusableCell(withIdentifier: cellId, for: indexPath) as! DeviceTableViewCell2

            if((chipnumber2.text?.isEmpty) != true) {

                let cellNew = tableView.dequeueReusableCell(withIdentifier: cellIdNew, for: indexPath) as! DeviceTableViewCell2

                let deviceItem: Device3New = itemsNew[indexPath.row]

                cellNew.badgeColor = UIColor.flatLime
                cellNew.badgeTextColor = .white;
                cellNew.badgeFontSize = 13;
                cellNew.badgeString = deviceItem.time
                cellNew.badgeOffset = CGPoint(x:30.0, y:63)

                cellNew.deviceItem3New = deviceItem
                cellNew.titleNew.text = deviceItem.title
                cellNew.title1New.text = deviceItem.places
                cellNew.titlesaatNew.text = deviceItem.time
                cellNew.buttonNew.isOn = deviceItem.state

                cellNew.tablerow = String (indexPath.row)

                cellNew.backgroundColor = UIColor(white: 1, alpha: 0.09)

                return cellNew


            }

            if((chipnumber.text?.isEmpty) != true) {

            let deviceItem: Device3 = items[indexPath.row]

            cell.badgeColor = UIColor.flatLime
            cell.badgeTextColor = .white;
            cell.badgeFontSize = 13;
            cell.badgeString = deviceItem.time
            cell.badgeOffset = CGPoint(x:30.0, y:63)

            cell.deviceItem3 = deviceItem
            cell.title.text = deviceItem.title
            cell.title1.text = deviceItem.places
            cell.titlesaat.text = deviceItem.time
            cell.button.isOn = deviceItem.state

            cell.tablerow = String (indexPath.row)


            cell.backgroundColor = UIColor(white: 1, alpha: 0.09)

                return cell

            }
            return cell

        }

    }

Create a protocol Device with common properties

protocol Device {
    //common properties of both struct
    var time: String { get }
    var title: String { get }
    var places: String { get }
    var state: String { get }
}

Confirm to this procol in both structs and add un common properties if you need

struct Device3New: Device {
    var time: String
    var title: String
    var places: String
    var state: String
    //other properties
    var myVar1: String
}
struct Device3: Device {
    var time: String
    var title: String
    var places: String
    var state: String
    //other properties
    var myVar2: String
}

Create a common array with the type of the above protocol

Now in numberOfRowsInSection method check chipnumber2.text!.isEmpty and chipnumber.text!.isEmpty and append the arrays to the common array. And in cellForRowAt get the object from the common array.

class NewMainTableViewController: UITableViewController {
    var items: [Device3] = []
    var itemsNew: [Device3New] = []
    var joinedItems: [Device] = []
    //chipnumber, chipnumber2 textfields
    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        joinedItems.removeAll()
        if !chipnumber2.text!.isEmpty {
            joinedItems.append(contentsOf: itemsNew)
        } else if !chipnumber.text!.isEmpty {
            joinedItems.append(contentsOf: items)
        }
        return joinedItems.count
    }
    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cellNew = tableView.dequeueReusableCell(withIdentifier: "cellIdNew", for: indexPath) as! DeviceTableViewCell2

        let deviceItem: Device = joinedItems[indexPath.row]
        //common properties
        print(deviceItem.time)
        print(deviceItem.title)
        print(deviceItem.places)
        print(deviceItem.state)
        //other properties
        if let deviceItem = joinedItems[indexPath.row] as? Device3New {
            print(deviceItem.myVar1)
        } else if let deviceItem = joinedItems[indexPath.row] as? Device3 {
            print(deviceItem.myVar2)
        }
        return cellNew
    }
}
