Follows #1325 (merged). Rebased onto main past that squash; the only merge fix was dropping a stored apikey in RealtimeClientV2 that #1323 had already made optional and nothing read.

What

Finishes the transport migration started in #1325: HTTPTypes is the working currency inside every module, not just at the seam.

  • Sources/Helpers/HTTP/: HTTPClient is the one internal seam. send(_:body:timeout:) takes an HTTPTypes.HTTPRequest plus Data? and returns (HTTPTypes.HTTPResponse, Data); stream(_:body:timeout:) keeps the streaming shape. The JSON Content-Type default lives in stream, before the middleware chain, so middlewares see what the transport sees. A package init HTTPRequest(method:url:query:headerFields:) owns query-item encoding. Helpers re-exports HTTPTypesFoundation alongside HTTPTypes.
  • Deleted: Helpers.HTTPRequest, Helpers.HTTPResponse, HTTPClientType, HTTPClientMock. Added Data.decoded(as:decoder:) (package) so the ~60 execute(...).decoded(...) sites in Auth and Storage are untouched, and RecordingTransport in TestHelpers for tests that inspect requests or stub responses.
  • Auth: APIClient.execute(_:body:) returns Data; APIClient.send(_:body:) returns the head too, for the two admin list endpoints that read pagination headers. Dependencies.http is HTTPClient.
  • PostgREST: builders store request: HTTPRequest plus query: [URLQueryItem] and body: Data?; the URL gets its query at execute(). carryingFrom: copies all three.
  • Storage: StorageApi.execute(_:body:) returns Data; StorageApi.upload(_:formData:options:) replaces the multipart HTTPRequest extension.
  • Functions and Realtime: call sites build HTTPRequest directly; per-request timeout is a send/stream parameter backed by the existing RequestTimeout task-local.
  • Public breaks (feat!): HTTPError.response, PostgrestResponse.response, AuthError.api(underlyingResponse:) and FunctionsClient.invoke(decode:) carry HTTPTypes.HTTPResponse instead of HTTPURLResponse. V3_MIGRATION.md gains one section covering all four, and the stale "HTTPURLResponse.url is now the request URL" behavior note from feat!: expose one public transport protocol and middleware chain across all modules #1325 is replaced.

Not done, on purpose: step 5 of SDK-1819 (headers: [String: String]HTTPFields on public configs). HTTPFields.init([String: String]) and .dictionary stay because those configs still need the bridge. No statusCode shim was added to HTTPTypes.HTTPResponse; the migration guide points at status.code.

Why

Two HTTPRequest types in one import graph was a papercut for every contributor (77 Helpers./HTTPTypes. qualifiers), the request conversion had no single owner, and a synthetic HTTPURLResponse was built on every response only to fill four public signatures. A non-URLSession transport paid that cost for nothing. Design notes are on SDK-1819.

Test plan

  • Every module suite migrated off HTTPClientMock to ClosureTransport / RecordingTransport, with no snapshot re-recording (request wire format is unchanged: same query encoding, same Content-Type default, same URLRequest.timeoutInterval).
  • HTTPClientTests cover chain order, Content-Type default, timeout task-local, head-before-body against the new signatures.
  • HTTPErrorTests, AuthErrorTests, PostgrestResponseTests rebuilt around HTTPTypes.HTTPResponse (including Content-Range count parsing via headerFields).

Verification

swift test --no-parallel --skip IntegrationTests
━ Test run with 1262 tests in 130 suites passed after 11.124 seconds with 1 known issue.

./scripts/format.sh        # no changes
./scripts/spell-check.sh   # CSpell: Files checked: 397, Issues found: 0 in 0 files.
./scripts/test-docs.sh     # exit 0, no warnings
grep -rn "Helpers.HTTPRequest\|Helpers.HTTPResponse\|HTTPClientType\|HTTPClientMock" Sources Tests   # empty
grep -rln HTTPURLResponse Sources   # Sources/Helpers/HTTP/URLSessionTransport.swift only

The one known issue is the pre-existing intentional mismatch in DeferredRequestSnapshotTests. Linux: swift build --build-tests in a swift:6.2 container exits 0. Test files that bridge Mocker / URLProtocol output still construct an HTTPURLResponse, since they sit on URLSession.

Reviewer notes

Start with Sources/Helpers/HTTP/HTTPClient.swift, then Sources/Auth/Internal/APIClient.swift, Sources/PostgREST/Legacy/PostgrestRequestBuilder.swift (execute) and Sources/Storage/StorageApi.swift. The Auth/Storage call-site churn is mechanical: url:/method: reorder to match the HTTPTypes init and body: moves out to the execute call.

Fixes SDK-1819

📝 Summary

Summary by CodeRabbit

  • Breaking Changes

    • HTTP responses now use the typed HTTPResponse model, including status and header access.
    • Custom request and response wrappers have been replaced by the standard HTTP types.
    • Function response decoders and error APIs now receive HTTPResponse.
  • Improvements

    • HTTP requests support separate bodies, headers, query items, and configurable timeouts.
    • Storage uploads and Realtime requests use the updated transport behavior.
  • Documentation

    • Added migration guidance for updating response handling to the new APIs.

Walkthrough

The pull request migrates the networking layer from custom HTTP request and response wrappers to HTTPTypes. Requests now separate heads, bodies, query items, and timeouts. Responses return an HTTPResponse head with separate body data. Auth, Functions, PostgREST, Realtime, and Storage clients use the new APIs. Tests use RecordingTransport, and migration documentation covers updated response access.

Priority: ➖ Normal

Merge Risk: 🟠 High · up to 366f8

The HTTP transport migration is broadly consistent, but the identity-linking path in the Auth client references the current session incorrectly and prevents the Auth module from building, which would break all consumers. The migration guide also contains a response-bridging example that will not compile when copied. Both should be fixed before merge.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Resolve the current session before constructing the request.

The header resolves session to AuthClient.session, whose getter is async throws. The code accesses it without try await while declaring the response variable with the same name, so linkIdentityWithIdToken does not compile. Fetch try await sessionManager.session() into currentSession and use currentSession.accessToken.

Not a bug: this is the same pattern main has today and it compiles (CI is green on both). Inside the initializer of the local session, the name resolves to AuthClient.session, whose async throwing getter is covered by the single try await on the outer expression. No change.

… across the HTTP layer

Modules now build `HTTPTypes.HTTPRequest` and hand `HTTPClient` a `Data?` body; `HTTPClient.send`
returns the `HTTPTypes.HTTPResponse` head plus the buffered body. `Helpers.HTTPRequest`,
`Helpers.HTTPResponse`, `HTTPClientType` and `HTTPClientMock` are deleted; tests stub the network
with `ClosureTransport` or the new `RecordingTransport`. The JSON `Content-Type` default and the
query-item encoding each have one owner (`HTTPClient.stream`, `HTTPRequest.init(method:url:query:
headerFields:)`), and no `HTTPURLResponse` is synthesized outside `URLSessionTransport`.

BREAKING CHANGE: `HTTPError.response`, `PostgrestResponse.response`,
`AuthError.api(underlyingResponse:)` and `FunctionsClient.invoke(decode:)` carry
`HTTPTypes.HTTPResponse` instead of `HTTPURLResponse`. See V3_MIGRATION.md.
