Design Patterns: Proximity and Swift: A Comprehensive Guide

In today’s world, software development has become an integral part of any organization. The need for robust and maintainable code is greater than ever before. Design patterns are a great way to ensure that your code is easily readable, understandable, and maintainable. In this blog post, we will be discussing the Proximity design pattern and how it works with Swift.

The Proximity design pattern is a powerful tool that helps developers create flexible and maintainable code. It enables developers to keep their code organized and easy to understand. This design pattern is based on the principle of proximity, which states that objects are more likely to interact when they are close together. The Proximity design pattern allows for efficient communication between objects by placing them in close proximity.

The Proximity design pattern can be implemented in Swift by using classes and structs. Classes are used to define object types, while structs are used to store data. By using structs, developers can create objects with specific properties that can be used to interact with other objects. The Proximity design pattern also makes use of protocols, which are used to define the behavior of objects. Protocols provide a set of rules which must be followed by objects in order to interact with each other.

To get started with the Proximity design pattern in Swift, you must first create a class or struct to represent the object type you want to work with. For example, if you want to create a button that will trigger an action when clicked, you would create a class called “Button”. This class would have two properties: a title for the button and an action that will be triggered when the button is clicked.

Once the class is created, you must define the behavior of the button by implementing the protocol “Actionable”. This protocol defines the methods that must be implemented in order to make the button interactive. The two methods that must be implemented are “performAction” and “getTitle”. The “performAction” method will be called when the button is clicked, and the “getTitle” method will be used to get the title of the button.

Once the class and protocol are defined, you can now use the Proximity design pattern to create objects that interact with each other. To do this, you must create a class called “ButtonGroup”, which will contain a collection of buttons. This class will have a method called “addButton”, which will add a button to the group. Once a button is added to the group, the group will call the “performAction” method of the button when it is clicked. This allows the group to interact with the buttons in a structured and organized manner.

The Proximity design pattern makes it easy to create objects that interact with each other in a structured and organized way. It also makes it easy to maintain and update code. By using this design pattern, developers can ensure that their code is robust and maintainable. 

class Button {
    var title: String
    var action: () -> ()
    
    init(title: String, action: @escaping () -> ()) {
        self.title = title
        self.action = action
    }
}

protocol Actionable {
    func performAction()
    func getTitle() -> String
}

extension Button: Actionable {
    func performAction() {
        action()
    }
    
    func getTitle() -> String {
        return title
    }
}

class ButtonGroup {
    var buttons = [Button]()
    
    func addButton(_ button: Button) {
        buttons.append(button)
    }
    
    func performActionForButtonWithTitle(_ title: String) {
        for button in buttons {
            if button.title == title {
                button.performAction()
            }
        }
    }
}

By using the Proximity design pattern, developers can create objects that interact with each other in a structured and organized way. This makes it easier to maintain and update code, as well as ensuring that the code is robust and maintainable. Design patterns are a great way to ensure that your code is easily readable, understandable, and maintainable.
