Hide Show Section According to server response swift-CodePudding

I am developing an app which used table view with multiple section and multiple header view. Is it possible to hide randomly section according to server response, i.e.: I have 6 Multiple cells and header view. I got response from the server which show only 2 sections, 4 section and 6 section. I am trying to achieve this, but didn't get success. Here is my code below:

Code:

var allPermissionSection = ["A","B","C","D","E","F"] // default permission 

override func numberOfSections(in tableView: UITableView) -> Int {
    return totalSectionTable // total count of showing cell
} 
 
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    let modelPermission = mainArrayCheckValidations[0] as! MyAcountModel
    if section == 0 {
        return 1
    }
    //  arraySectionName got from server check index if default section or server reponse index is equal to same then true this continue
    if allPermissionSection[0] == arraySectionName[0] {
            if arrayTblItems.count > 0 {
                return arrayTblItems.count
            }else if modelPermission.phoneNumbersEnabled ==  true {
                return 1
            }
    }
    if allPermissionSection[1] == arraySectionName[1] {
            if arrayTblItemsForElectronic.count > 0 {
                return arrayTblItemsForElectronic.count
            }else if modelPermission.econsentEnabled ==  true {
                return 1
            }
    }
    if allPermissionSection[2] == arraySectionName[2] {
            if arrayTblItemsForEmergnceContact.count > 0 {
                return arrayTblItemsForEmergnceContact.count
            }else if modelPermission.emergencyContactsEnabled ==  true {
                return 1
            }
    }
    return 0
}

So, Here is the my code please let me know if i m doing wrong please correct me

Can someone please explain to me hide or show randomly section,

Any help would be greatly appreciated.

Thanks in advance.
