How do I convert a C file to Swift with LetsConvert?

Upload your .c or .h file, select SWIFT as the target language, then choose optional settings such as comment preservation and memory-safe rewrites. Click Convert and review the output in the side-by-side editor. For multi-file projects, convert each C translation unit separately and use the Swift files in your Xcode project.

Why should I convert C code to Swift?

C requires manual memory management and unsafe pointer handling, while Swift uses ARC and strong typing to prevent common crashes. Converting lets you reuse legacy C algorithms inside iOS, macOS, watchOS, and tvOS apps without relying on a bridging header, and makes the codebase easier to maintain with Swift's protocol-oriented design.

How does the C-to-Swift conversion preserve pointer, struct, and macro behavior?

Structs are mapped to Swift structs, #define constants become computed properties or static let values, and pointers are typically converted to optional, inout, or pointer-safe wrappers with explicit null checks. Constructs with no direct Swift equivalent—such as unions, raw pointer arithmetic, and variable-length arrays—are flagged for manual review instead of being converted silently.

Is C-TO-SWIFT free to use?

Yes, C-TO-SWIFT 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! C-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.
