Extension To Class Swift at Alexis Hayes blog

Extension To Class Swift. in this swift tutorial, i’ll show you how to add new functionality to existing swift classes using class extensions. We can achieve this using an extension. extensions in swift allow you to extend an existing class, struct, enumeration, or protocol with new functionality. We use the extension keyword. Whether it’s a custom type defined by you or a current type inside of a framework, extensions can create custom accessors and enhance the types you work with. Implementing protocols as separate extensions. lately, though, i have seen that apple suggests using extensions to an even greater extent, e.g. at its core, an extension is a way to augment existing types without modifying their source code. in swift, we can add new functionality to existing types. extensions, well, extend existing swift named types — i.e., structs, classes, enums, and protocol — so you can add more functionality to them. In other words, you can extend the functionality of classes, structs, enums, and protocols that. This enables you to insert your own code into existing system code to which you wouldn’t otherwise have access, such as the foundation framework.
