How do I convert CS (C#) to SWIFT using this tool?

Paste your C# code into the input box or upload a .cs file, select SWIFT as the target language, and click "Convert". The tool will parse your code and generate Swift syntax, including class declarations, methods, and variable types. Then copy the converted code or download it as a .swift file. For larger projects, use the batch upload feature to convert multiple .cs files at once.

Why should I convert C# to Swift?

Converting C# to Swift is essential when porting your application from .NET (e.g., Windows or Xamarin) to Apple platforms like iOS and macOS. Swift is optimized for Apple's hardware and integrates seamlessly with Xcode and APIs like UIKit and Combine. Converting your code lets you reuse business logic while adapting the UI layer, reducing development time compared to rewriting from scratch. It also ensures you take advantage of Swift's memory safety and performance.

How does the converter handle C# features like nullable types, async/await, and LINQ?

The converter is designed to map C# constructs to their Swift equivalents. Nullable value types are translated to Swift optionals. async/await methods become Swift async functions with the appropriate error handling. LINQ queries are converted to Swift's higher-order functions like map, filter, and reduce. However, some platform-specific libraries cannot be translated automatically; these are flagged for manual review so you can adjust them to Swift-native APIs.
