fix(ant-dev): dispatcher swift no-skip + lua LUA_PATH wrap#86
Merged
Conversation
Two unrelated dispatcher bugs surfaced when running the full
`ant dev example data -l <lang>` sweep across all 15 SDKs on Linux.
## swift
The adapter shipped with `skip_reason="REST/gRPC SDK is macOS-only per
antd-swift README"`, so swift was silently auto-skipped on every run.
The README claim is outdated — the swift toolchain on Linux (swift.org
release, 6.0.x) builds and round-trips against antd end-to-end. Replace
the skip with a real adapter that runs `swift run AntdExamples N`,
mirroring the csharp/kotlin number-arg pattern.
## lua
`luarocks --local --lua-version=5.4 make` installs the rock under
`~/.luarocks/share/lua/5.4/antd/`, which `lua5.4` doesn't pick up by
default. The adapter just called `lua5.4 examples/02-data.lua`, so the
example fataled with `module 'antd' not found`. Wrap the run via
`bash -c 'eval "$(luarocks --local --lua-version=5.4 path)" && exec
lua5.4 "examples/$1"'` so the freshly-installed rock is on
LUA_PATH/LUA_CPATH for the subprocess.
Filename comes from the `examples` dict (static), passed as a positional
arg to the inner shell — no string interpolation into the command line.
## Test plan
Verified end-to-end on a Linux dev box (Ubuntu 24.04, Swift 6.0.3,
Lua 5.4):
- [x] `ant dev example data -l swift` — round-trip OK, real
`Estimate: 24 bytes in 3 chunks, ...` (no skip)
- [x] `ant dev example data -l lua` — round-trip OK
("Public data round-trip OK!")
- [x] Other 13 SDKs unchanged (cpp/csharp/dart/elixir/go/java/js/
kotlin/php/python/ruby/rust/zig) — full sweep 15/15 green

The Swift SDK is documented as macOS-only in `antd-swift/README.md`, but
in practice the swift.org Linux toolchain (6.0.x) builds and round-trips
against antd end-to-end after a small set of upstream-fixable patches.
This PR collects them and adds a snake-case-decoding fix for the cost
estimate that was hiding behind the "macOS-only" framing.
Verified end-to-end on Ubuntu 24.04 with Swift 6.0.3:
`swift build && swift run AntdExamples 2` → "Public data round-trip OK!"
with real `Estimate: 24 bytes in 3 chunks, storage 43945312500000000
atto, gas 150000000000000 wei, mode single`.
## Changes
### Package.swift — bump grpc-swift to 2.x
`grpc-swift-protobuf 1.x` requires Swift tools 6.0+, which conflicts
with the previous `from: "1.23.0"` pin on `grpc-swift` (which is on the
1.x line, requiring 5.x tooling). Bump `grpc-swift` to `2.0.0` and add
the new `grpc-swift-nio-transport` package — `GRPCNIOTransportHTTP2`
moved out of the main grpc-swift repo in 2.x.
### AntdRestClient.swift — three fixes
1. **`FoundationNetworking` import** — Linux builds split URLSession out
of `Foundation` into a separate `FoundationNetworking` module.
Guarded with `#if canImport(...)` so macOS/iOS are unaffected.
2. **PUT-response cost is optional** — daemon's `POST /v1/data/public`,
`/v1/data/private`, `/v1/chunks` currently return `{address,
chunks_stored, payment_mode_used}` without `cost`, so the previous
`let cost: String` decoder fataled. Mirrors the antd-php / antd-py
fallback to empty-string. Same shape addressed in #77 (kotlin) and
the long-standing PHP/Python pattern.
3. **CostDTO snake_case decoding** — the bug hidden by today's e2e:
`JSONDecoder.snakeCase` (which is `keyDecodingStrategy =
.convertFromSnakeCase`) converts JSON `file_size` → expected Swift
property `fileSize`. CostDTO had snake_case property names, so
decoding silently nilled them out and `dataCost` / `fileCost` always
returned zero for `fileSize`/`chunkCount`/`gas`/`mode`. Rename to
camelCase so the decoder matches.
### Errors.swift — `override` keyword on subclass inits
Swift 6's stricter init resolution flagged the 9 error subclass
initializers as missing `override` against `AntdError.init(_:statusCode:)`.
Add the keyword.
### AntdExamples/Main.swift — Linux-safe minimal example
The previous bundled example used `SecRandomCopyBytes` from Apple's
`Security` framework (macOS-only) and had pre-existing arity bugs in
several of the per-example helper functions. Replace with a minimal
Linux-portable example 02 that exercises the public data round-trip and
exits non-zero on mismatch — enough for cross-SDK e2e validation. The
full example suite would be a separate restoration once
`SecRandomCopyBytes` is replaced and the arity bugs are fixed.
## Test plan
- [x] `cd antd-swift && swift build` clean on Ubuntu 24.04 with Swift
6.0.3 (one cosmetic warning: `dependency 'grpc-swift' is not used
by any target` — only the nio-transport sub-package is used)
- [x] `swift run AntdExamples 2` against a local devnet — round-trip OK,
real estimate fields
- [x] Cross-SDK e2e harness: 15/15 SDKs pass, swift no longer skipped
## Companion PR
PR adding `swift run AntdExamples N` to the `ant dev example`
dispatcher (and removing the `skip_reason` that was auto-skipping
swift) is in #86. Either can land first; without the antd-swift
patches here, the dispatcher's swift adapter will fail at compile.

Cuts v0.7.1 atop v0.7.0. Primarily refreshes the upstream `ant-core` pin to the `ant-cli-v0.2.3` release tag (no API change for antd consumers).
