Sukari
Description
Enjoy Beutiful Syntactic Enhancements that will save you Hundreds Or Thousands of lines of Code
Simply add Sukari to your initializers
-
this()is an extension on all NSObject subclasseslet fileManager = FileManager().this { $0.urls(for: .applicationDirectory, in: .userDomainMask) }
Clean up your initialization Code
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.
let tableView = UITableView().this {
$0.backgroundColor = .white
$0.register(UserCell.self, forCellReuseIdentifier: "CellID")
$0.separatorStyle = .none
$0.allowsSelection = false
}Easily copy value Types
Easy Customization
Use your own Types With a simple Extension
extension CustomType: Sukari {}
let instance = CustomType().this {
$0.color = .blue
$0.label.text = "Custom Type"
}A Real World Example
class LoginViewController : UIViewController {
var loginButton = UIButton().this {
$0.setTitle("Login", for: .normal)
$0.backgroundColor = . yellow
$0.layer.masksToBounds = true
$0.layer.cornerRadius = 5
}
override func viewDidLoad() {
super.viewDidLoad()
view.addSubview(loginButton)
}
}
Unwrap
Unwrap lets you easily require Optional values to be non-nil, or crash with ease.
Often Times you have to handle many optionals in your code Using Guard or If let in order to unwrap optional values in your code.
This Has Two Problems.
- It Causes Code Congestion, making your code harder to read and maintain
- After Unwrapping with
GuardorIf letyou recieve absolutely No debuging information.
Unwrap Solves these problems by providing Syntactical Sugar to your code.
Quickly and easy unwrap your optionals with .unwrap and provide debug information such as which line and file the crash happened with .unwrap(debug:)
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
Descriptive Debug Messages
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
