- Click the convert button.
- The resulting Swift code from the conversion will be displayed in the output box.
Examples
The following are examples of code conversion from Objective-C to Swift using this converter. Note that you may not always get the same code since it is generated by an AI language model which is not 100% deterministic and gets updated from time to time.
Example 1 - Is String Palindrome
Program that checks if a string is a palindrome or not.
Objective-C
Swift
Example 2 - Even or Odd
A well commented function to check if a number if odd or even.

Key differences between Objective-C and Swift
| Characteristic | Objective-C | Swift |
|---|---|---|
| Syntax | Objective-C uses a C-style syntax with Smalltalk-style messaging. | Swift uses a more modern and concise syntax inspired by several programming languages. |
| Paradigm | Objective-C is a superset of C and supports both procedural and object-oriented programming paradigms. | Swift is a multi-paradigm language that supports both object-oriented and functional programming paradigms. |
| Typing | Objective-C is a dynamically typed language. | Swift is a statically typed language with type inference. |
| Performance | Objective-C has good performance and is widely used in iOS and macOS development. | Swift is designed to be fast and provides performance improvements over Objective-C. |
| Libraries and frameworks | Objective-C has a large number of libraries and frameworks available. | Swift has a growing ecosystem of libraries and frameworks, and is compatible with Objective-C libraries. |
| Community and support | Objective-C has a mature and established community with extensive documentation and support. | Swift has a rapidly growing community and is actively supported by Apple with regular updates and improvements. |
| Learning curve | Objective-C has a steeper learning curve compared to Swift. | Swift has a relatively easier learning curve, especially for developers familiar with modern programming languages. |
Frequently Asked Questions
How do I convert Objective-C to Swift?
Paste your Objective-C code into the input box, confirm the languages are set to Objective-C and Swift, and click Convert. CodeConvert AI analyzes your Objective-C code and generates equivalent Swift code in seconds, preserving the original logic and structure.
What are the main differences between Objective-C and Swift?
Objective-C and Swift differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each Objective-C construct to its closest Swift equivalent. See the comparison table below for the key differences between Objective-C and Swift.
Is the converted Swift code accurate?
The AI produces high-quality Swift code that preserves the behavior of your original Objective-C code and follows Swift conventions. It handles common patterns, data structures, and idioms for both Objective-C and Swift. For large or performance-critical code, review and test the Swift output before using it in production.
Can I convert an entire Objective-C project to Swift?
You can convert Objective-C files one at a time by pasting each file's code. For a full migration, convert each file and then review how classes, dependencies, and project structure map from Objective-C to Swift. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
Can I convert Swift back to Objective-C?
Yes. CodeConvert AI converts in both directions, so you can convert Swift to Objective-C just as easily using our Swift to Objective-C converter. Try the Swift to Objective-C Converter
Is the Objective-C to Swift converter free, and do I need to install anything?
Yes, it is free and runs in your browser with nothing to install and no IDE extension required. You can convert Objective-C to Swift without an account for up to 5 conversions per day. Sign in for free for higher limits.
What are the benefits of signing in?
Signing in unlocks CodeConvert AI's Pro converter with more powerful AI models, a built-in chat assistant, code execution, saved conversion history, and personal notes. Every free account includes 5 credits and supports up to 25,000 characters of input per conversion, with no credit card required.
