✨ Super sweet syntactic sugar for Swift initializers.
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
}()-
You can use
then()to all ofNSObjectsubclasses.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("devxoul@gmail.com", forKey: "email") $0.synchronize() }
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)
}
}-
