Add Data Sorting in TableView with Exception | Swift - swift

Question

Essentially I currently have the following JSON Parse logic in place to group and present the JSON Array in a tableview.
Currently in the fetchJSON function I am grouping person and sorting alphabetically. How can I add logic that makes an exception to this sort and allows person = Jack, to always be on top of the sort and the rest stay alphabetical.
Is there a way to keep the person = "Jack" at the top of the tableview no matter the other tableview data?
Below is my current code:
private func fetchJSON() {
guard let url = URL(string: "\(BaseURL.url)test.php"),
let value = variable.addingPercentEncoding(withAllowedCharacters: .urlQueryValueAllowed)
else { return }
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.httpBody = "test=\(value)".data(using: .utf8)
URLSession.shared.dataTask(with: request) { data, _, error in
guard let data = data else { return }
do {
let decoder = JSONDecoder()
decoder.keyDecodingStrategy = .convertFromSnakeCase
let res = try decoder.decode([Portfolio].self, from: data)
let grouped = Dictionary(grouping: res, by: { $0.person })
let keys = grouped.keys.sorted()
self.sections = keys.map({Section(name: $0, items: grouped[$0]!)})
DispatchQueue.main.async {
self.tableView.reloadData()
}
}
catch {
print(error)
}
}.resume()
}
Structure:
struct Section {
let name : String
var items : [Portfolio]
}
struct Portfolio: Decodable {
let person: String
let serial: String
var checkbox: Int
var isSelected : Bool {
get { return checkbox == 1 }
set { checkbox = newValue ? 1 : 0 }
}
enum CodingKeys : String, CodingKey {
case person, serial, checkbox
}
}

I think you can do that in multiple ways to your own custom sort. But for coding simplicity, you can consider this alternative solution. After sorting, remove, and insert the item again.
var keys = grouped.keys.sorted()
if let index = keys.firstIndex(of: "jack") {
let jack = keys.remove(at: index)
keys.insert(jack, at: 0)
}
