Language comparison
Key differences between Swift and Dart
| Characteristic | Swift | Dart |
|---|---|---|
| Syntax | Swift has a syntax that is similar to many other modern programming languages, making it easy to read and write. | Dart has a syntax that is similar to JavaScript and other C-style languages, making it familiar to many developers. |
| Paradigm | Swift is a multi-paradigm language that supports both object-oriented and functional programming. | Dart is a multi-paradigm language that supports both object-oriented and functional programming. |
| Typing | Swift is a statically-typed language, which means that variable types are checked at compile-time. | Dart is a optionally-typed language, which means that variable types can be specified but are not required. |
| Performance | Swift is known for its high performance and efficiency, making it suitable for resource-intensive applications. | Dart is designed to be fast and efficient, but it may not perform as well as some other languages in certain scenarios. |
| Libraries and frameworks | Swift has a growing ecosystem of libraries and frameworks, including popular ones like SwiftUI and Alamofire. | Dart has a growing ecosystem of libraries and frameworks, including popular ones like Flutter and AngularDart. |
| Community and support | Swift has a large and active community, with plenty of resources and support available for developers. | Dart has a growing community, with an increasing number of resources and support available for developers. |
| Learning curve | Swift has a relatively low learning curve, especially for developers familiar with other modern programming languages. | Dart has a relatively low learning curve, especially for developers familiar with JavaScript and other C-style languages. |
Common questions
Frequently Asked Questions
How do I convert Swift to Dart?
Paste your Swift code into the input box, confirm the languages are set to Swift and Dart, and click Convert. CodeConvert AI analyzes your Swift code and generates equivalent Dart code in seconds, preserving the original logic and structure.
What are the main differences between Swift and Dart?
Swift and Dart differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each Swift construct to its closest Dart equivalent. See the comparison table below for the key differences between Swift and Dart.
Is the converted Dart code accurate?
The AI produces high-quality Dart code that preserves the behavior of your original Swift code and follows Dart conventions. It handles common patterns, data structures, and idioms for both Swift and Dart. For large or performance-critical code, review and test the Dart output before using it in production.
Can I convert an entire Swift project to Dart?
You can convert Swift 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 Swift to Dart. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
Can I convert Dart back to Swift?
Yes. CodeConvert AI converts in both directions, so you can convert Dart to Swift just as easily using our Dart to Swift converter. Try the Dart to Swift Converter
Is the Swift to Dart 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 Swift to Dart without an account for up to 2 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.
