+# pdftract-swift-publish WorkflowTemplate
+#
+# Publishes the Swift SDK to github.com/jedarden/pdftract-swift by creating a git tag.
+# Triggered by the pdftract-release-cascade after pdftract-build-binaries completes.
+# The workflow clones the Swift SDK repo, syncs the version, runs conformance
+# tests, creates a git tag matching the binary version, and pushes it.
+# Swift Package Manager is git-tag-based, so the tag IS the version.
+#
+# === Parameter Reference ===
+# - tag: Git tag from the main repo (e.g., v1.0.0)
+# - version: SemVer version string (e.g., 1.0.0)
+#
+# === Steps ===
+# 1. clone-sdk-repo: Clone github.com/jedarden/pdftract-swift
+# 2. sync-version: Update Package.swift (SPM doesn't require explicit version)
+# 3. conformance: Run swift test --filter ConformanceTests (must pass to publish)
+# 4. tag-and-push: Create and push git tag VERSION (numeric, no v prefix)
+# 5. warm-spi: Post the tag to Swift Package Index to trigger indexing
+#
+# === Re-runnability ===
+# A re-run after a partial failure will detect the existing tag and skip the push
+# step (idempotent). The workflow is safe to re-run.
+#
+# === SPM Tag Format ===
+# SPM tags use NUMERIC format only: 1.0.0, not v1.0.0
+# The workflow strips the 'v' prefix from the binary tag when creating the SPM tag.
+#
