Initable

Initialize views/controllers from code/xib/storyboard with one simple interface .initiate()

Controllers example:

// Controller without nib.
class FooController: UIViewController, CodeInitable { }
let foo = FooController.initiate()

// Controller with xib named "FooContoller"
class BarController: UIVewController: XibInitable {
    static var xibName: String { "FooContoller" }
}
let bar = BarController.initiate()

// Controller with storyboard named "BazStoryboard" with id "BazControllerId"
class BazController: UIVewController: StoryboardInitable {
    static var storyboardId: String { "BazControllerId" }
    static var storyboardName: String { "BazStoryboard" }
}
let baz = BazController.initiate()

Initable Example

BundleFileReader

Reading custom object/JSON/Data from Bundle.

Bundle contains foo.json file.

{
    "bar": 100
}

Reading:

struct Foo {
    let bar: Int
}

let foo: Foo = BundleFileReader.readObject("foo")

LocalNotificationService

Lightweight tool for managing local notifications. Tools:

1. Use requestAuthorization to request User's approve for sending notifications
2. Use getAuthorizationStatus to check current authorization status
3. Use willPresent to ask the delegate what to do after receiving notification
4. Use didRecieve to inform delegate about receiving notification

Example:

LocalNotificationService.shared.getAuthorizationStatus { status in
    if status == .authorized { 
        // Do some...
    } else {
        // Do another...
    }
}

Extensions

Useful extensions for all code situations

let number = Float.two // 2.0
let closure = Closure.Int // (Int) -> Void
let color = UIColor(hex: "#FFFFFF") // White Color
// and others

Extensions example

MulticastDelegate

MulticastDelegate hepls to manage more than one delegate.

protocol FooDelegate: AnyObject { 
    func bar()
 }

let multicastDelegate = MulticastDelegate<FooDelegate>()

multicastDelegate.add(delegate: object)
multicastDelegate.remove(delegate: object)

multicastDelegate.invokeForEachDelegate { delegate in
    delegate.bar()
}

UIKit.View(Controller) Preview

Live preview for UIKit views/controllers.

class FooView: UIView { ... }

struct FooView_Previews: PreviewProvider {
    static var previews: some View {
        ViewPreview {
            FooView()
        }
    }
}

Button

Base button class with a lots of customization.

Usage from code:

class FooButton: Button { }

Usage from nib:

1. Set your button class to Button in IB
2. Set Type = Custom in IB
3. Set Style = Default in IB

Layout

Simple view layout

let superview = UIView()
let subview = UIView()

superview.layoutSubview(subview, with: LayoutInsets.zero, safe: true)

StackView

StackView with item content builder.

let items = (0..<10).map { Int($0) }
let stackView = ItemsStackView<Int, UILabel>(
    axis: .horizontal,
    distribution: .fill,
    alignment: .fill,
    spacing: 10,
    edgeInsets: .zero,
    items: items
) { item in
    let label = UILabel()
    label.text = "\(item)"
    
    return label
}
