+## Swift/SwiftUI Integration Plan
+
+The Swift implementation for Ditto CoT library follows a 7-phase approach:
+
+### Phase 1: Foundation & Schema Integration (2-3 weeks)
+- Swift Package Manager setup with proper module structure
+- Schema code generation (JSON Schema → Swift Codable types)
+- Build integration with existing Makefile system
+- CI/CD pipeline extension for Swift builds and tests
+
+### Phase 2: Core CoT Event Handling (3-4 weeks)
+- CoTEvent model with builder pattern (similar to Rust implementation)
+- XML parsing/serialization using XMLCoder or custom parser
+- Event validation against XSD schema
+- Type-safe event builders for each CoT event type
+
+### Phase 3: Ditto SDK Integration (2-3 weeks)
+- Document conversion following established CRDT optimization patterns
+- Observer integration with Combine framework
+- Async/await support for modern Swift concurrency
+- R-field reconstruction handling
+
+### Phase 4: SwiftUI Integration Layer (2-3 weeks)
+- ObservableObject wrappers for CoT event streams
+- View models for common CoT event display patterns
+- Data binding utilities for real-time updates
+- SwiftUI-specific convenience APIs
+
+### Phase 5: Testing Infrastructure (3-4 weeks)
+- Unit tests using XCTest framework
+- Integration tests with mock Ditto instances
+- Cross-language validation tests against Java/Rust implementations
+- SwiftUI UI tests for interface components
+- Performance benchmarks using XCTMetric
+
+### Phase 6: Documentation & Examples (1-2 weeks)
+- Swift-specific documentation following existing patterns
+- Example iOS/macOS app demonstrating full integration
+- Migration guides from other Ditto SDK patterns
+- API reference generation using Swift-DocC
+
+### Phase 7: Advanced Features & Optimization (2-3 weeks)
+- CRDT optimization refinements for Swift-specific patterns
+- Memory management optimization for iOS constraints
+- Background processing support for iOS/macOS apps
+- SwiftUI performance optimizations for large event lists
+
+### Implementation Principles
+- Protocol-oriented design following Swift best practices
+- Value types where appropriate for thread safety
+- Reference types for stateful components (stores, converters)
+- Modern concurrency with async/await and actors where beneficial
+- Platform-specific considerations for iOS/macOS/watchOS/tvOS
