How do I convert Kotlin code to Swift with LetsConvert?

Paste your Kotlin source into the editor, choose Swift as the output language, and click Convert. Review the generated Swift file for platform-specific APIs like Android SDK calls, then adjust type mappings for optionals and closures.

Why would a developer convert Kotlin to Swift instead of rewriting from scratch?

Converting preserves business logic, data models, and algorithm structure, reducing migration effort when porting Android apps to iOS. You avoid introducing bugs from manual translation, though platform-specific framework calls (e.g., Android Activity vs SwiftUI/UIKit) still require manual adaptation.

How does the conversion preserve Kotlin's null-safety and coroutines in the Swift output?

Kotlin's nullable types (String?) become Swift optionals (String?) with explicit unwrapping in logic. Coroutines (suspend functions) are mapped to Swift async/await functions; structured concurrency uses Task and Continuation accordingly. Sealed classes become Swift enums with associated values, and data classes map to structs when possible.

Is KOTLIN-TO-SWIFT free to use?

Yes, KOTLIN-TO-SWIFT 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! KOTLIN-TO-SWIFT 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.
