SearchPushRow for Eureka 3.0 (Swift 3.1)

Project.swift

// Add SearchItem protocol to the model (here Project)
extension Project: SearchItem {
  func matchesSearchQuery(_ query: String) -> Bool {
    return name.lowercased().contains(query.lowercased())
  }
}

SearchPushRow.swift

import Eureka

// swiftlint:disable type_name
open class _SearchSelectorViewController<T: Equatable, Row: SelectableRowType>: _SelectorViewController<Row>, UISearchResultsUpdating where Row: BaseRow, Row: TypedRowType, Row.Cell.Value == T, T: SearchItem {

    definesPresentationContext = true

    if let allRows = form.first?.map({ $0 }) as? [ListCheckRow<T>] {
      originalOptions = allRows
      currentOptions = originalOptions
    }

    tableView.tableHeaderView = searchController.searchBar
  }

  public func updateSearchResults(for searchController: UISearchController) {
    guard let query = searchController.searchBar.text else { return }
    if query.isEmpty {
      currentOptions = originalOptions
    } else {
      currentOptions = originalOptions.filter { $0.selectableValue?.matchesSearchQuery(query) ?? false }
    }
    tableView.reloadData()
  }

  open override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return currentOptions.count
  }

  open override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let option = currentOptions[indexPath.row]
    option.updateCell()

  open override func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
    return nil
  }

  open override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    currentOptions[indexPath.row].didSelect()
  }
}
// swiftlint:enable type_name

open class SearchSelectorViewController<T: Equatable>: _SearchSelectorViewController<T, ListCheckRow<T>> where T: SearchItem {}

// swiftlint:disable type_name
open class _SearchPushRow<Cell: CellType> : SelectorRow<Cell, SearchSelectorViewController<Cell.Value>> where Cell: BaseCell, Cell.Value: SearchItem {
  public required init(tag: String?) {
    super.init(tag: tag)
    presentationMode = .show(controllerProvider: ControllerProvider.callback { return SearchSelectorViewController<Cell.Value> { _ in } }, onDismiss: { vc in
      _ = vc.navigationController?.popViewController(animated: true) })
  }
}
// swiftlint:enable type_name

public final class SearchPushRow<T: Equatable> : _SearchPushRow<PushSelectorCell<T>>, RowType where T: SearchItem {
  public required init(tag: String?) {
    super.init(tag: tag)
  }
}

public protocol SearchItem {
  func matchesSearchQuery(_ query: String) -> Bool
}

Simply add the SearchPushRow.swift file to your project, add SearchItem protocol to your model and use SearchPushRow instead of PushRow in your code.

Do you have an update for this with Eureka 4.0.1? Getting a lot of errors:

@noefroidevaux did you upgrade to Eureka 4 ?

Updated to Eureka 4.0.1 and Swift 4
