Online Swift Compiler
Write Swift in the browser and run it on our machines. The editor is opening.
Free online Swift compiler and editor
JDoodle is an online IDE that has served the programming community since 2013. You write, compile, and run code in the browser for Swift and many other languages, without installing a toolchain.
What you see on this page is JDoodle’s free Swift compiler. Write Swift in the editor, press Execute, and JDoodle runs it on its servers. You do not install Swift, and you do not need a JDoodle account to run code.
Online Swift editor
JDoodle’s Swift editor on this page highlights syntax, completes as you type, matches brackets, and folds blocks. It is an online Swift editor and a compiler together: you write here, then Execute runs your program on JDoodle’s servers.

Frequently asked questions
Is JDoodle’s online Swift compiler free?
Yes. JDoodle lets you write and run Swift without paying. A JDoodle account is only needed to save projects, use more AI credits, or unlock faster workspaces.
Do I need to install Swift to use JDoodle?
No. JDoodle runs Swift on its servers. Open this page in a browser and execute.
Which Swift version should I pick on JDoodle?
Choose the version that matches the course or codebase you are working against from the version menu. The builds JDoodle has installed are 2.2, 3.1.1, 4.1, 5.1, 5.5, 5.9.1, and Swift 6.2.4.
Can I add Libraries on JDoodle?
Yes, if the package is public. Private or local packages are not supported on this JDoodle page.
Can I run a multi-file Swift project online?
Not on this page, which runs a single Swift file. One file starts faster, so this page suits exercises and practice. For classes, packages and libraries split across files, open the JDoodle Swift IDE. Everything else works the same on both.
Is this an online Swift editor or a compiler?
Both. The page is an online Swift editor and it compiles and runs what you write.
Input, interactive runs, files, and the rest of the editor work the same on every language. See the JDoodle IDE documentation.
