- 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 Python 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.

Key differences between Python and Swift
| Characteristic | Python | Swift |
|---|---|---|
| Syntax | Python has a clean and readable syntax with a focus on code readability and simplicity. | Swift has a modern and concise syntax that is similar to Python, but with some additional features like optionals and type inference. |
| Paradigm | Python supports multiple programming paradigms including procedural, object-oriented, and functional programming. | Swift is a multi-paradigm language that supports both object-oriented and functional programming. |
| Typing | Python is dynamically typed, which means that variable types are determined at runtime. | Swift is statically typed, which means that variable types are checked at compile-time. |
| Performance | Python is an interpreted language and generally has slower performance compared to compiled languages like Swift. | Swift is a compiled language and generally has faster performance compared to interpreted languages like Python. |
| Libraries and frameworks | Python has a vast ecosystem of libraries and frameworks for various purposes, including web development, data analysis, and machine learning. | Swift has a growing ecosystem of libraries and frameworks, but it is not as extensive as Python's. |
| Community and support | Python has a large and active community with extensive documentation and support resources. | Swift has a growing community, but it is not as large or mature as Python's. However, it is backed by Apple and has official documentation and support. |
| Learning curve | Python has a relatively easy learning curve, especially for beginners, due to its simple syntax and readability. | Swift has a moderate learning curve, especially for those with prior programming experience. It may be more challenging for beginners. |
Frequently Asked Questions
How do I convert Python to Swift?
Paste your Python code into the input box, confirm the languages are set to Python and Swift, and click Convert. CodeConvert AI analyzes your Python code and generates equivalent Swift code in seconds, preserving the original logic and structure.
What are the main differences between Python and Swift?
Python 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 Python construct to its closest Swift equivalent. See the comparison table below for the key differences between Python and Swift.
Is the converted Swift code accurate?
The AI produces high-quality Swift code that preserves the behavior of your original Python code and follows Swift conventions. It handles common patterns, data structures, and idioms for both Python and Swift. For large or performance-critical code, review and test the Swift output before using it in production.
Can I convert an entire Python project to Swift?
You can convert Python 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 Python 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 Python?
Yes. CodeConvert AI converts in both directions, so you can convert Swift to Python just as easily using our Swift to Python converter. Try the Swift to Python Converter
Is the Python 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 Python 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.
