Packages generated Swift bindings and matching native libraries for the provider-neutral alias SDK. The API includes injected provider adapters, alias lifecycle operations, journals, reconciliation, and encrypted login references, alongside the current vault, encryption metadata, registration, and restricted-view contracts. The matched source includes patched TLS dependencies.

Distribution and compatibility

The GPL-only XCFramework contains arm64 iOS device and arm64 iOS simulator slices. SwiftPM pins an immutable archive URL and checksum. Bindings, FFI headers, and native libraries share the source identity recorded in package provenance and must be regenerated together. Intel simulator and standalone watchOS SDK slices are not included.

The package verifier checks archive contents, source pairing, platform slices, and alias ABI. Its no-argument mode supports this local native build. Candidate-directory mode requires separate preverified evidence and rejects local-native provenance. Comparing Sigstore bundle bytes does not establish signature trust or CI attestation.

Verification

Local qualification passed locked native builds, simulator and unsigned-device consumer builds, six tests against the distributed package, archive/provenance checks, and ABI symbol checks for both slices. The verifier correction passed local-native validation and five negative contract cases. The review discussion explains that contract.

The test follow-up passed three affected cases through the matching native boundary, including exact contact-removal dispatch and identity, and asynchronous permission-denied propagation. Binding/planning/tombstone tests cover plaintext contract behavior. Generated sources, archive, native libraries, provenance, and the iOS package pin are unchanged.

Remaining limits

This distribution has no hosted build attestation. The producer SDK's newly published journal, reference-validation, and reconciliation-order fixes are not in these native libraries. Integrating them requires a qualified matching package and consumer validation.

The shared RSA dependency's expired advisory exception remains unresolved in SDK #3. Historical native qualification does not clear that risk. Generated Swift async polling does not establish prompt cancellation of native or network work. Authenticated alias, encrypted-sync, recovery, and changed-UI acceptance remain pending in iOS #2.

📝 Walkthrough

Walkthrough

The Swift package adds generated UniFFI bindings across SDK modules, support code, alias-reference tests, updated package and release metadata, and scripts for deterministic XCFramework packaging and provenance verification.

Changes

Swift SDK package and release

Layer / File(s) Summary
Core, crypto, and encoding bindings
Sources/BitwardenSdk/BitwardenApiBase.swift, Sources/BitwardenSdk/BitwardenCrypto.swift, Sources/BitwardenSdk/BitwardenEncoding.swift
Adds public API and crypto types, Rust FFI converters, serialization, handle management, and contract-version checks. Crypto bindings add key and signature types, and update selected key fields and converters.
Domain bindings
Sources/BitwardenSdk/BitwardenCollections.swift, Sources/BitwardenSdk/BitwardenImporters.swift, Sources/BitwardenSdk/BitwardenManagedSettings.swift, Sources/BitwardenSdk/BitwardenOrganizations.swift, Sources/BitwardenSdk/BitwardenPolicies.swift
Adds domain models, errors, converters, optional-value handling, and module initialization checks.
Client and generator bindings
Sources/BitwardenSdk/BitwardenExporters.swift, Sources/BitwardenSdk/BitwardenGenerators.swift, Sources/BitwardenSdk/BitwardenCryptoSyncHandler.swift, Sources/BitwardenSdk/BitwardenRandom.swift, Sources/BitwardenSdk/BitwardenServerCommunicationConfig.swift
Adds client interfaces, typed errors, generator request fields, and asynchronous FFI handling. The username-generator API removes the forwarded case.
Additional bindings and support
Sources/BitwardenSdk/BitwardenPM.swift, Sources/BitwardenSdk/BitwardenSensitiveValue.swift, Sources/BitwardenSdk/BitwardenSsh.swift, Sources/BitwardenSdk/BitwardenState.swift, Sources/BitwardenSdk/BitwardenUnlock.swift, Sources/BitwardenSdkSupport/NaiveDateFormatter.swift, Package.swift
Adds additional generated bindings and strict yyyy-MM-dd date parsing and formatting. The package adds the support target.
Package metadata and alias-reference tests
PACKAGE_VERSION, VERSION, ALIAS_REFERENCE_SCHEMA_VERSION, ALIAS_SDK_PROVENANCE.json, LICENSE_GPL.txt, README.md, Tests/BitwardenSdkTests/BitwardenSdkTests.swift
Updates package, source, schema, and artifact provenance; adds the GPL license and package documentation; and adds alias-reference serialization, lifecycle, access-control, reconciliation, and edit tests.
Artifact packaging and verification
scripts/canonicalize-zip.py, scripts/create-xcframework-zip.sh, scripts/verify-provider-neutral-alias.sh
Adds ZIP canonicalization and deterministic XCFramework packaging. The verifier checks package provenance, archive contents and symbols, and optional release-candidate evidence.

Review details

Systems and components

  • observed — Sources (service) was modified; 19 changed files map to changed impact.
  • observed — scripts (service) was modified; 3 changed files map to changed impact.
  • observed — ALIAS_REFERENCE_SCHEMA_VERSION (service) was modified; 1 changed file maps to changed impact.
  • observed — ALIAS_SDK_PROVENANCE.json (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

  • observed — Modified behavior in ALIAS_REFERENCE_SCHEMA_VERSION: The file now contains the value 1.
  • observed — Modified behavior in LICENSE_GPL.txt: Added the complete GPL version 3 license text, covering definitions; permissions and conditions for conveying source and object code; user-product installation information; additional terms; termination; downstream licensing; patents; warranty and liability disclaimers; and instructions for applying the license to new programs.
  • observed — Modified behavior in PACKAGE_VERSION: The package version is set to 0.3.0-alias-provider-neutral.2.
  • observed — Modified behavior in Sources/BitwardenSdk/BitwardenApiBase.swift: Adds FFI buffer and byte conversions, serialization readers and writers, and converter protocols. By-reference bytes only support scope-bound lowering; the other converter operations trap. Buffer reads report overflow, and Rust-buffer lifting rejects trailing data.

Assert contact removal dispatch, arguments and async error propagation through the matched native boundary. Name callback and plaintext journal checks for the guarantees they exercise.
