π― Sweet Syntactical Sugar For Swift
Simply add Sukari to your initializers
Use .this{} to Initialize Swiftly! π
let fileManager = FileManager().this {
$0.urls(for: .applicationDirectory, in: .userDomainMask)
}
Clean up your initialization Code! β¨
let tableView : UITableView = {
let table = UITableView()
table.backgroundColor = .white
table.register(UserCell.self, forCellReuseIdentifier: "CellID")
table.separatorStyle = .none
table.allowsSelection = false
return table
}()Initialize in this way. and and stop repeating yourself! π¦
let tableView = UITableView().this {
$0.backgroundColor = .white
$0.register(UserCell.self, forCellReuseIdentifier: "CellID")
$0.separatorStyle = .none
$0.allowsSelection = false
}Easily Create and Set Value Types π
let point = CGPoint().set {
$0.x = 100
$0.y = 200
}Add Sugar to your own Types with a little Extension π
extension CustomType: Sukari {}
let instance = CustomType().this {
$0.color = .blue
$0.label.text = "Custom Type"
}Make your code base a little Sweeter π
class LoginViewController : UIViewController {
var loginButton = UIButton().this {
$0.setTitle("Login", for: .normal)
$0.backgroundColor = . yellow
$0.layer.masksToBounds = true
$0.layer.cornerRadius = 5
}
let emailTextField = UITextField().this {
$0.placeholder = "Email"
$0.borderStyle = .roundedRect
$0.font = UIFont.systemFont(ofSize: 14)
$0.backgroundColor = UIColor(white: 0, alpha: 0.03)
}
override func viewDidLoad() {
super.viewDidLoad()
view.addSubview(loginButton)
view.addSubview(emailTextField)
}
}
Unwrap
Unwrap lets you easily require Optional values.
Use unwrap() on any optional that you expect to always be non-nil, or else crash your App with a more (optional) descriptive debug message with .unwrap(debug:)
On top of that, unwrap also provides a sytactic enhancement to easily unwrap optionals through an under-the-hood Guard Statement.
- No More

Adopt this simple but effective enhancment to your code base Now!

Usage
Call unwrap() on any Optional, optionally giving a debugMessage for debugging purposes:
struct Person {
let name: String
let email: String
init(dictionary: [String: Any]) {
name = dictionary["name"].unwrap(debug: "Unable to find json Element Name") as! String
email = dictionary["email"].unwrap(debug: "Unable to find json Element Email") as! String
}
}
let dictionary = ["ame": "Chris", "email": "chrisbkarani@gmail.com"]
let chris = Person(dictionary: dictionary)
print(chris.name) //Chris
print(chris.email) // chrisbkarani@gmail.com
Another Real-World Example
Without Using Unwrap
class LoginController: UIViewController {
var token: Token?
override func viewDidLoad() {
super.viewDidLoad()
// more code is more bugs
guard let unwrappedToken = token else {
// if this crashes we enter a 'nil' state in our app with no debug information
return
}
LoginService.login(unwrappedToken)
}
}With Unwrap
class LoginController: UIViewController {
var token: Token?
override func viewDidLoad() {
super.viewDidLoad()
LoginService.login(token.unwrap())
}
}Installing
