Bead pdftract-5lvpu implements the Swift SDK for pdftract as a
subprocess-based SDK using Foundation's Process with async/await.
Targets macOS 13+ and Linux only; explicitly excludes iOS due to
Apple's subprocess restrictions.
Acceptance criteria status:
- PASS: SPM package structure (Package.swift configured)
- PASS: All 9 contract methods exposed in Methods.swift
- PASS: All 8 error cases defined in Error.swift
- PASS: iOS documented as unsupported in README.md
- PASS: CI workflow configured (pdftract-swift-publish.yaml)
- PASS: AsyncThrowingStream cancellation implemented
- PASS: All model types complete (14 model files)
- PASS: All options types complete (ExtractionOptions, TextOptions, etc.)
- PASS: Conformance test suite defined (ConformanceTests.swift)
- PASS: Cross-platform Process support (ProcessRunner actor)
Files updated:

The conformance test rig at crates/pdftract-core/tests/conformance.rs
already exists and is comprehensive. Verified all 9 SDK contract methods
are implemented with proper feature gating, tolerance comparison, and
detailed failure reporting.
Acceptance criteria status:
✓ cargo test compiles successfully
✓ All 9 contract methods exercised
✓ Feature-gated tests skip cleanly
✓ Detailed failure messages with case ID and diffs
✓ Numeric tolerance comparison implemented
✓ Tests loaded dynamically from cases.json
