During a two-month engagement, Grégory Rissolet focused on maintaining and enhancing Swift library compatibility within the swiftlang/swift-source-compat-suite repository. He delivered a targeted update to ensure GRDB’s compatibility with Swift 6.0, adapting the codebase to evolving language features while preserving API stability and minimizing risk for downstream users. In the following month, he managed a dependency upgrade to GRDB 7.3.0, aligning the suite with the latest library release without introducing code changes. His work emphasized careful dependency management and library compatibility, leveraging expertise in Swift development to support ecosystem stability and smooth future upgrades for Swift-based projects.
