How do I convert an Objective-C file to Kotlin with LetsConvert?

To convert Objective-C code to Kotlin, open the LetsConvert tool, paste or upload your .m/.h files, select Kotlin as the target language, and click 'Convert'. The tool automatically translates syntax, maps APIs, and preserves comments. You can then copy or download the resulting Kotlin file.

Why would I convert Objective-C to Kotlin?

Converting Objective-C to Kotlin is useful when migrating an iOS or macOS app to Android, or when moving to Kotlin Multiplatform for shared business logic. Kotlin offers null safety, more concise syntax, and coroutines for async tasks, making code easier to maintain. Objective-C's dynamic runtime and messaging differ from Kotlin's static typing, so conversion helps align with modern development practices.

What happens to Objective-C categories, protocols, and blocks when converted to Kotlin?

LetsConvert maps Objective-C categories to Kotlin extension functions, protocols to interfaces (sometimes sealed classes), and blocks to lambdas. Memory management (ARC) is converted to Kotlin's garbage collection, and nil messaging is handled using nullable types. Dynamic runtime calls are replaced with safer statically-typed equivalent patterns where possible, preserving the original logic and copyright comments.
