AddThen

🎨 View instance sugar for Swift & UIKit

Example

Add UIView & UIViewController code with AddThen

let label = UILabel()
label.backgroundColor = .red
label.text = "Hello, World"

...

view.addSubview(label)

This is equivalent to :

let label = UILabel()

...

view.add(label) {
  $0.backgroundColor = .red
  $0.text = "Hello, World!"
}

view.add(
  UIStackView { 
    UIButton()
    UIView()
    UIImageView()
  }
)

Also very useful with SnapKit

let label = UILabel()

...

view.add(label) {
  $0.backgroundColor = .red
  $0.text = "Hello, World!"
  
  $0.snp.makeConstraints {
    $0.edges.equalToSuperview()
  }
}

More SwiftUIfully

/// in certain function in UIViewController
let label = UILabel()

body {
    label.then({ $0.textColor = .red })
    UIButton()

}

body {
    if true {
        UIView()
    } else {
        EmptyView() // EmptyView will not be added 
    }
}

if you want to handle certain view which should not be added, use Emptiable or EmptyView
