Various iOS extensions for creating reusable views in code

Button.swift

import UIKit

extension UIButton {
    static func createBordered(light: Bool) -> UIButton {
        let button = UIButton(type: .roundedRect)
        button.contentEdgeInsets = UIEdgeInsets(top: 5, left: 7, bottom: 5, right: 7)
        button.layer.cornerRadius = 5
        button.translatesAutoresizingMaskIntoConstraints = false
        if (light) {
            button.backgroundColor = UIColor.white
            button.setTitleColor(UIColor.primary, for: .normal)
        }
        return button
    }
}

Label.swift

import UIKit

extension UILabel {
    static func createTitle(text: String, light: Bool, oversized: Bool) -> UILabel {
        let label = UILabel()
        label.translatesAutoresizingMaskIntoConstraints = false
        label.backgroundColor = UIColor.clear
        label.textColor = light ? UIColor.white : UIColor.primary
        label.font = UIFont.systemFont(ofSize: oversized ? 36 : 22, weight: UIFontWeightThin)
        label.adjustsFontForContentSizeCategory = true
        label.text = text
        return label
    }
}

TextField.swift

import UIKit

extension UITextField {

    static func createDefault(_ placeholder: String?) -> UITextField {
        let textField = UITextField()
        textField.borderStyle = .roundedRect
        textField.backgroundColor = UIColor.white
        textField.placeholder = placeholder
        textField.translatesAutoresizingMaskIntoConstraints = false
        return textField
    }

    static func createPassword(_ placeholder: String?) -> UITextField {
        let textField = createDefault(placeholder)
        textField.isSecureTextEntry = true
        return textField
    }
}
