ApplyStyleKit

May 21, 2025

ApplyStyleKit is a library that applies styles to UIKit using Swifty Method Chain.

Normally, when applying styles to UIView etc.,it is necessary to write propertyName and equal operator many times.

With ApplyStyleKit, you can comfortably apply style to your code.

Like this:


                                              
                                                sampleLabel.applyStyle

.backgroundColor(.yellow)

.text(“sample label”)

.textAlignment(.center)

.textColor(.green)

.font(.boldSystemFont(ofSize: 30.0))

.numberOfLines(0)

Installation

Requirements

iOS 9.0 or late
Swift 4.2
Xcode 10

Carthage


                                              
                                                github “shindyu/ApplyStyleKit”

CocoaPods


                                              
                                                target ‘<Your Target Name>’ do

pod ‘ApplyStyleKit’

end

Usage


                                              
                                                import ApplyStyleKit
class ViewController: UIViewController {

let sampleView = UIView()

let sampleLabel = CustomLabel()
override func viewDidLoad() {

super.viewDidLoad()
// Apply style

sampleView.applyStyle

.backgroundColor(.red)

.alpha(0.5)
// When applying to layer

sampleView.layer.applyStyle

.cornerRadius(10)

.borderColor(.gray)

.borderWidth(2)
// Of course, you can apply it if you inherit UIView etc.

sampleLabel.applyStyle

.text(“Of course, you can apply it if you inherit UIView etc.”)

.textAlignment(.center)

.textColor(.green)

.font(.boldSystemFont(ofSize: 30.0))

.numberOfLines(0)

}

}

Advanced

You can also create your own applyStyleMethod.

To be able to define the extension, the access modifier of base which is a property of StyleObject is public.

example:


                                              
                                                extension StyleObject where Base: UIView {

@discardableResult func specialStyle() -> StyleObject {

base.backgroundColor = .red

base.layer.cornerRadius = 10

return self

}

}

Support

QuartzCore

✅ CALayer

UIKit

✅ UIView

✅ UILabel

✅ UIButton

✅ UIImageView

✅ UISwitch

✅ UIControl

✅ UIStackView

✅ UISlider

✅ UITableView

✅ UICollectionView

Basic policy

ApplyStyleKit intends to target methods with no return value and properties with setter. Due to the nature of ApplyStyleKit, I think that returning types other than StyleObject should be avoided.
