April 2025 (2025-04) monthly summary for sprucekit-mobile: Delivered key enhancements and stability improvements focused on the mobile SDK's reliability and readiness for SSI-related features. Core dependency and runtime improvements align SSI dependencies across the Rust project and upgrade the runtime usage for exported FFI methods, boosting stability and enabling future SSI capabilities. A targeted login bug fix restored reliable login functionality by reverting the Swift Tools Version to 5.3, adjusting Swift language mode, and correcting a login error handler typo. These changes reduce risk, improve user experience, and position the mobile SDK for upcoming SSI features.

February 2025: Delivered end-to-end vehicle-title presentation via OID4VP in mobile flows, enabling the mobile SDK to act as a holder for verifiable credentials and support vehicle-title presentation paths. Implemented OID4VP-based presentation in spruceid/mobile-sdk-rs and sprucekit-mobile, including flexible holder authorization handling, enhanced credential presentation logic, and support for new credential formats. Upgraded to mobile-sdk-rs v0.9.0 in sprucekit-mobile to align dependencies and enable a smoother release cycle. Demonstrated strong cross-repo collaboration, robust dependency management, and a focus on business value by streamlining secure vehicle-title verifications in mobile apps and laying groundwork for broader verifiable-credential scenarios.

January 2025 monthly summary for sprucekit-mobile: Focused on refining the release workflow to align with main before updating Package.swift, resulting in more reliable mobile package updates and smoother releases.

December 2024 – SpruceKit-Mobile: Delivered interoperability and security enhancements across the mobile credential stack. Key features include standardizing OID4VP credential presentations with a PresentationSigner; enabling DID methods and VCDM 2.0 verification in VC Playground; adding DID-method utilities and VCDM v2 support in Mobile SDK; introducing bitstring status list support for LDP VC to improve VC status handling; along with release workflow improvements and dependency upgrades to boost reliability and security. Fixed issues include descriptor map path handling for single-credential scenarios, invalid signature handling in VC Playground, and DER encoding fixes for verifiable presentation signatures. These workstreams collectively improve interoperability, cryptographic robustness, and release quality, accelerating time-to-value for customers deploying interoperable credential workflows.

November 2024 monthly summary for sprucekit-mobile (spruceid/sprucekit-mobile). Two major feature streams were delivered: OID4VP library upgrade and VP token handling improvements, and a new delegated verifier for OID4VP. These changes enable multi-credential VP creation and submission flows, improved error handling, and scalable verification across Swift and Rust implementations. The work reduces integration risk, improves interoperability with input descriptor path handling, and strengthens test coverage.
