How do I convert Swift to Objective-C using this tool?

Paste your Swift code into the input box, select 'Swift' as source and 'Objective-C' as target, then click 'Convert'. The tool will translate syntax, including optionals, closures, and generics, into equivalent Objective-C constructs. You can copy the output from the right panel or download it as a .m file.

Why would I convert Swift to Objective-C?

Converting Swift to Objective-C is useful for integrating Swift code into legacy iOS/macOS projects that are primarily written in Objective-C, or when using older third-party APIs and libraries that require Objective-C syntax. It also helps bridge the gap when migrating or refactoring codebases.

How does the conversion handle optional chaining, closures, and protocol-oriented patterns?

Our converter maps Swift optionals to Objective-C's nullable annotations (`_Nullable`), closures to blocks (`^` syntax), and protocol extensions to categories or helper classes. Swift's type inference is replaced with explicit typing, and generic functions become lightweight abstractions. Some runtime-specific behaviors, like Swift's name mangling, are resolved to Objective-C runtime equivalents.

Is SWIFT-TO-OBJECTIVE-C free to use?

Yes, SWIFT-TO-OBJECTIVE-C on LetsConvert is 100% free with no registration or hidden fees required.

Are my uploaded files safe and secure?

Does this converter work on mobile phones and tablets?

Yes! SWIFT-TO-OBJECTIVE-C works seamlessly across iPhone, Android, iPad, Mac, Windows, and Linux browsers without installing any app.

Is there any software installation required?

No software or browser extension installation is needed. All conversions are performed directly online.
