- Created clean module separation: - SpineC: C/C++ compilation only (working) - SpineSwift: Generated Swift bindings + platform-agnostic API - SpineiOS: iOS-specific UI components only - Updated Package.swift with proper target structure - Moved generated Swift files to SpineSwift/Generated - Removed redundant SpineModule - Created test with skeleton_drawable_test.swift ported from Dart - Test successfully runs using SpineC module directly - Note: SpineSwift has Objective-C selector conflicts to be fixed
