Swift

How does Swift work with Objective-C code in the same project?

The question is about Swift .

Answer:

Swift works fully with Objective-C, allowing both languages in the same app. Developers can use a bridging header to give Swift access to Objective-C classes, methods, and properties. Objective-C can also run Swift code marked with the @objc attribute. This lets teams update or add new features in Swift without rewriting all the old code. You can easily use Objective-C libraries in Swift, helping you reuse existing resources and make a smooth, gradual switch to Swift in mixed-code projects.
