Code

• A template for creating TableViewAdapter, shortcut: Table View Adapter Code

    import UIKit

    protocol <#Your#>TableViewAdapterOutput {
    }

    final class <#Your#>TableViewAdapter: NSObject {
        // MARK: - Properties

        private let output: <#Your#>TableViewAdapterOutput

        private var items: [String]
        private var tableView: UITableView

        // MARK: - Initialization and deinitialization

        init(tableView: UITableView, output: <#Your#>TableViewAdapterOutput) {
            self.output = output
            self.tableView = tableView
            self.items = []
            super.init()
            setupTable()
        }

        // MARK: - Internal methods

        func configure(with items: [String]) {
            self.items = items
            tableView.reloadData()
        }

        // MARK: - Private methods

        private func setupTable() {
            tableView.delegate = self
            tableView.dataSource = self
            tableView.register(
                UINib(nibName: String(describing: <#Your#>TableViewCell.self), bundle: nil),
                forCellReuseIdentifier: String(describing: <#Your#>TableViewCell.self)
            )
        }
    }

    // MARK: - UITableViewDataSource

    extension <#Your#>TableViewAdapter: UITableViewDataSource {
        func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
            return items.count
        }

        func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
            let cell = tableView.dequeueReusableCell(
                withIdentifier: String(describing: <#Your#>TableViewCell.self),
                for: indexPath
            ) as? TableViewCell
            cell?.backgroundColor = .red
            return cell ?? <#Your#>UITableViewCell()
        }
    }

    // MARK: - UITableViewDelegate

    extension <#Your#>TableViewAdapter: UITableViewDelegate {
        func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
            tableView.deselectRow(at: indexPath, animated: true)
        }
    }

• A code block for creating user property in UserDefaults extension, shortcut: Defaults Key Code

    var <#defaultsKey#>: <#Type#> {
        get { return <#typeof#>(forKey: #function) }
        set { set(newValue, forKey: #function) }
    }

• A code block for layouting child view anchors equal to the parent view anchors, shortcut: Constraints - layout child as parent Code

    <#childView#>.translatesAutoresizingMaskIntoConstraints = false

    NSLayoutConstraint.activate([
        <#childView#>.topAnchor.constraint(equalTo: <#parentView#>.safeAreaLayoutGuide.topAnchor, constant: 0),
        <#childView#>.bottomAnchor.constraint(equalTo: <#parentView#>.safeAreaLayoutGuide.bottomAnchor, constant: 0),
        <#childView#>.leadingAnchor.constraint(equalTo: <#parentView#>.safeAreaLayoutGuide.leadingAnchor, constant: 0),
        <#childView#>.trailingAnchor.constraint(equalTo: <#parentView#>.safeAreaLayoutGuide.trailingAnchor, constant: 0)
        ])

  static let <#notificationName#> = NSNotification.Name("<#projectName#>.notifications.<#notificationName#>")

• A code block for creating template comments for unit test, shortcut: testtemplate Code

  // given

  // when

  // then

   ```swift
  func addKeyboardObservers() {
        NotificationCenter.default.addObserver(self,
                                               selector: #selector(keyboardWillShow),
                                               name: UIResponder.keyboardWillShowNotification,
                                               object: nil)
        NotificationCenter.default.addObserver(self,

                                               object: nil)
    }

    @objc
    func keyboardWillShow(notification: NSNotification) {
        guard
            let frame = notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue
        else {
            return
        }
