See how Swift’s protocol-oriented programming makes building objects easier and more efficient for developers.

When Apple announced the release of Swift, the first protocol-oriented language, at their Worldwide Developers Conference (WWDC) in 2015, it indicated a shift away from their existing object-oriented programming, Objective-C.

But because Objective-C utilizes implicit sharing inheritance, creating new objects becomes a slow process, and the new objects often have functionalities that are unneeded. In this case, if a class hierarchy is complex, maintaining it can cause problems like inefficiency and race conditions.

With Swift’s protocol paradigm, developers can now build objects without inheritance, objects can be used by existing code, and a single class can work with multiple protocols without the need for inheritance.

In this post, we’ll discuss Swift’s protocol paradigm and its advantages. Knowledge of object-oriented programming is helpful for understanding this post’s content.
