Swift Format is made by Apple. If your Xcode Version is latest version (after Xcode 16), you don’t need to install it. Toolchain contains swift format.
xcrun --find swift-format
///Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift-format
https://github.com/swiftlang/swift-format?tab=readme-ov-file#configuring-the-command-line-tool
Step 1. Create swift-format.json
swift-format dump-configuration > swift-format.json
//It will show default settings for formatting and listing
Copied default settings and create a file like swift-format.json in your project root directory.

Step 2. Add Build Script
echo "🐥 Formatting"
swift-format format --configuration swift-format.json --ignore-unparsable-files -i -p -r ${PROJECT_DIR}
echo "🐥 Linting"
swift-format lint --configuration swift-format.json --ignore-unparsable-files -p -r ${PROJECT_DIR}
Step 3. Build Project
Okay It works
