Language comparison
Key differences between Dart and Swift
| Characteristic | Dart | Swift |
|---|---|---|
| Syntax | Dart has a C-style syntax with curly braces and semicolons. | Swift has a syntax that is similar to Objective-C, but with a more modern and concise approach. |
| Paradigm | Dart supports both object-oriented programming and functional programming paradigms. | Swift is a multi-paradigm language that supports both object-oriented programming and functional programming paradigms. |
| Typing | Dart is a statically typed language, which means that variable types are checked at compile-time. | Swift is a statically typed language, which means that variable types are checked at compile-time. |
| Performance | Dart is designed to be fast and efficient, with a focus on optimizing performance. | Swift is designed to be fast and efficient, with a focus on optimizing performance. |
| Libraries and frameworks | Dart has a growing ecosystem of libraries and frameworks, including Flutter for building cross-platform mobile apps. | Swift has a rich ecosystem of libraries and frameworks, including SwiftUI for building user interfaces. |
| Community and support | Dart has a supportive community and is backed by Google, which provides documentation, tutorials, and resources. | Swift has a large and active community, with support from Apple, which provides extensive documentation, tutorials, and resources. |
| Learning curve | Dart has a relatively low learning curve, especially for developers familiar with C-style languages. | Swift has a moderate learning curve, especially for developers familiar with C-style languages. |
Common questions
Frequently Asked Questions
How do I convert Dart to Swift?
Paste your Dart code into the input box, confirm the languages are set to Dart and Swift, and click Convert. CodeConvert AI analyzes your Dart code and generates equivalent Swift code in seconds, preserving the original logic and structure.
What are the main differences between Dart and Swift?
Dart 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 Dart construct to its closest Swift equivalent. See the comparison table below for the key differences between Dart and Swift.
Is the converted Swift code accurate?
The AI produces high-quality Swift code that preserves the behavior of your original Dart code and follows Swift conventions. It handles common patterns, data structures, and idioms for both Dart and Swift. For large or performance-critical code, review and test the Swift output before using it in production.
Can I convert an entire Dart project to Swift?
You can convert Dart 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 Dart 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 Dart?
Yes. CodeConvert AI converts in both directions, so you can convert Swift to Dart just as easily using our Swift to Dart converter. Try the Swift to Dart Converter
Is the Dart 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 Dart 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.
