A native macOS and iOS application for viewing and editing EULUMDAT (LDT) and IES photometric files.

• Multiple Diagram Types: Polar, Cartesian, Butterfly, 3D, Heatmap, BUG Rating, LCS
• File Import/Export: LDT, IES, and SVG formats
• Batch Conversion: Convert multiple files at once
• Validation: Built-in validation with warnings and errors
• Templates: Pre-configured luminaire templates
• Interactive 3D: SceneKit-based 3D photometric solid visualization

1. Xcode 15+ (for macOS/iOS development)
2. Rust (for building the core library)
3. Swift Package Manager (included with Xcode)

1. Build the XCFramework (required before first build):

   cd /path/to/eulumdat-rs
   ./scripts/build-xcframework.sh

   This script:

   • Installs required Rust targets (iOS, macOS simulator, macOS)
   • Generates UniFFI Swift bindings
   • Builds the Rust library for all platforms
   • Creates the swift/eulumdat_ffiFFI.xcframework

2. Build the Swift App:

   cd EulumdatApp
   swift build

   Or open EulumdatApp.xcodeproj in Xcode and press ⌘R to build and run.

⚠️ XCFramework is NOT committed to git

• The swift/eulumdat_ffiFFI.xcframework/ directory is gitignored
• It must be generated locally by running ./scripts/build-xcframework.sh
• CI/CD pipelines should run this script as part of the build process

⚠️ User-specific files are gitignored

• xcuserdata/ and *.xcuserstate (Xcode user settings)
• .build/ directories (build artifacts)
• See .gitignore for complete list

This means the XCFramework hasn't been built. Run:

./scripts/build-xcframework.sh

The Swift bindings may be out of date. Rebuild the XCFramework:

./scripts/build-xcframework.sh

Clean and rebuild:

cd EulumdatApp
rm -rf .build
swift build
