+## Swift
+
+Swift formatting is enforced with `swift-format` default utility from Apple.
+To install and run it on all the files in the project, use the following command:
+
+```bash
+brew install swift-format
+swift-format . -i -r
+```
+
+The style is controlled by the `.swift-format` JSON file in the root of the repository.
+As there is no standard for Swift formatting, even Apple's own `swift-format` tool and Xcode differ in their formatting rules, and available settings.
