Delivered a Swift compatibility upgrade for google/oss-fuzz in 2026-04, focusing on updating the Swift toolchain and fuzzing environment to align with the latest Swift releases and base OS versions. The work ensures continued fuzzing coverage against up-to-date Swift projects and reduces maintenance risk by deprecating older Swift versions (e.g., 5.x) in favor of Swift 6.2. Implemented via commit 9f7e10fb1ebe349f494bd1cef5f30a23f77bafe3, with changes spanning compiler/runtime upgrades and Dockerfile/project config adjustments. This reinforces OSS-Fuzz's ability to discover vulnerabilities in modern Swift software and maintains alignment with upstream Swift ecosystem.
