Swift FAQ
Do I need to install Swift to use this?
No. The Swift 6.0 runtime runs in your browser via CodeLab's embedded editor. Open the compiler, pick Swift, and press Run.
Is running Swift online free?
Yes. The CodeLab Playground is free with no account. Optional paid plans add privacy and larger limits — see the pricing page.
