How do I convert a SWIFT file to CS using LetsConvert?

Simply paste your Swift code into the left editor, choose 'CS' (C#) as the output language, and click 'Convert'. The tool instantly translates your classes, methods, and comments. You can then copy the C# code or download it as a .cs file.

Why convert from SWIFT to CS?

Converting Swift to C# allows you to share business logic between iOS and .NET applications, significantly reducing development time. It also enables cross-platform projects with Xamarin or .NET MAUI and simplifies migrating existing Swift codebases to Windows or Azure services.

How does the conversion handle Swift-specific features like Optionals and async/await?

Our converter preserves core type safety: Swift Optionals map to C# nullable types, and async/await translates directly to .NET's Task-based async pattern. Generic constraints, closures, and comments are also maintained. However, iOS-specific APIs (e.g., UIKit) require manual adaptation, as they have no direct C# equivalents.

Is SWIFT-TO-CS free to use?

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

Are my uploaded files safe and secure?

Yes! File privacy and security are guaranteed. Basic conversions run locally in your browser. Files sent for server processing are automatically deleted within 1 hour.

Does this converter work on mobile phones and tablets?

Yes! SWIFT-TO-CS 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.
