The Bridge design pattern is a useful concept for implementing separation of concerns in your code. It allows you to create a bridge between two different abstraction layers, allowing you to keep your code organized and maintainable.
At its core, the Bridge pattern involves creating a protocol that defines the contract for an object. This contract is then implemented by a concrete class that provides the actual implementation of the object's functionality.
One of the key advantages of using the Bridge pattern is that it allows you to easily change the implementation of an object without affecting its underlying abstraction. This can be particularly useful when you need to swap out one implementation for another, or when you need to update the implementation of an object without affecting its abstraction.
For example, let's say you have a GUI application that uses a variety of different buttons. You could create an abstract Button class that defines the protocol for a button, and then create concrete classes for each type of button (e.g. RoundButton, SquareButton, etc.) that implement the Button protocol. This would allow you to easily change the implementation of your buttons without affecting their underlying abstraction.
Here is an example of how to implement the Bridge pattern in Swift. First, we create an abstract Button class that defines the functionality for a button:

Next, we create a `ButtonImplementation` protocol that defines the methods that a button implementation must implement:
Finally, we create concrete classes for each type of button that implement the ButtonImplementation protocol:
We can now create instances of the Button class, passing in the appropriate button implementation for each button:
This allows us to easily change the implementation of our buttons without affecting their underlying abstraction. For example, we could create a new button implementation for a rectangular button and easily swap it out for the square button implementation:
The Bridge design pattern is a powerful tool for creating organized, maintainable, and extensible code. By separating the abstraction and implementation of an object, you can easily change and extend your code without affecting its underlying functionality.
