Apply Swift Format

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.

SampleProject/
├── 📱 SampleProject.xcworkspace
├── 🔧 SampleProject.xcodeproj
│
├── swift-format.json               # Swift Format
├── 📦 Main App & Server
│   ├── SampleProject/              # iOS 
│   ├── SampleProjectTests/
│   └── SampleProjectServer/        # Server
│
├── 🧩 Modules (Core Libraries)
│
├── 📦 Dependencies
│   └── Packages/                  # SPM packages
│
└── 📄 Config Files
    ├── SampleProject.xcconfig
    └── GoogleService-Info.plist

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
