Then

Swift CocoaPods Build Status

✨ Super sweet syntactic sugar for Swift initializers.

At a Glance

Initialize UILabel then set its properties.

let label = UILabel().then {
  $0.textAlignment = .center
  $0.textColor = .black
  $0.text = "Hello, World!"
}

This is equivalent to:

let label: UILabel = {
  let label = UILabel()
  label.textAlignment = .center
  label.textColor = .black
  label.text = "Hello, World!"
  return label
}()

Tips and Tricks

  • You can use then() to all of NSObject subclasses.

    let queue = OperationQueue().then {
  $0.maxConcurrentOperationCount = 1
}

  • Want to use with your own types? Just make extensions.

    extension MyType: Then {}

let instance = MyType().then {
  $0.really = "awesome!"
}

  • Use with() when copying the value types.

    let newFrame = oldFrame.with {
  $0.size.width = 200
  $0.size.height = 100
}
newFrame.width // 200
newFrame.height // 100

  • Use do() to do something with less typing.

    UserDefaults.standard.do {
  $0.set("devxoul", forKey: "username")
  $0.set("[email protected]", forKey: "email")
  $0.synchronize()
}

Real World Example

Here's an example usage in an UIViewController subclass.

final class MyViewController: UIViewController {

  let titleLabel = UILabel().then {
    $0.textColor = .black
    $0.textAlignment = .center
  }

  let tableView = UITableView().then {
    $0.backgroundColor = .clear
    $0.separatorStyle = .none
    $0.register(MyCell.self, forCellReuseIdentifier: "myCell")
  }

  override func viewDidLoad() {
    super.viewDidLoad()
    self.view.addSubview(self.titleLabel)
    self.view.addSubview(self.tableView)
  }

}
