From cbaec52c205542916cb9e84e10eb25bec2bc38e4 Mon Sep 17 00:00:00 2001 From: jedarden Date: Mon, 1 Jun 2026 11:44:14 -0400 Subject: [PATCH] fix(pdftract-5lvpu): add lc_first filter to Swift method names for proper naming Swift method names should start with lowercase (extract, extractText, etc.). The lc_first filter was already registered in the code generator but not applied to method declarations. This fixes the template to use lowercase method names matching Swift conventions. Verification: - All 9 contract methods generate with correct naming - All 8 error cases generate correctly - Package.swift specifies macOS 13+ and Linux support - README documents iOS as unsupported - Argo workflow synced to declarative-config Closes pdftract-5lvpu Verification note: notes/pdftract-5lvpu.md --- notes/pdftract-5lvpu.md | 152 ++++++++++++++++++ .../PdftractCodegen/Methods.swift.tera | 12 +- 2 files changed, 158 insertions(+), 6 deletions(-) create mode 100644 notes/pdftract-5lvpu.md diff --git a/notes/pdftract-5lvpu.md b/notes/pdftract-5lvpu.md new file mode 100644 index 0000000..1841c08 --- /dev/null +++ b/notes/pdftract-5lvpu.md @@ -0,0 +1,152 @@ +# Swift SDK Implementation Verification (pdftract-5lvpu) + +## Summary +The Swift SDK templates and Argo Workflow for publishing are fully implemented and tested. + +## Verification Results + +### ✅ Swift Package Manager Templates +Location: `templates/sdk-skeleton/swift/` + +**Files generated:** +- `Package.swift` -
