Swift's runtime now ignores safety-disabling environment variables in privileged processes, and JetBrains is cutting Kotlin's Gradle support at the knees.

Swift's runtime now ignores SWIFT_* environment variables in setuid/setgid binaries, and in platform-binary or hardened-runtime executables it will also skip variables that disable safety checks [1]. This is a hard security win for anyone shipping privileged Swift tooling. Meanwhile, Kotlin is shedding test code for Gradle 8.9 through 8.13 in four separate PRs [2][3][4][5], a signal that the build system is moving on. Flutter's tooling got three Windows fixes: UNC path resolution in depfile parsing [6], argParser wrap-column handling [7], and a swap of deprecated wstring_convert for native Win32 APIs [8]. The team also unskipped web decoration image lerp tests [9], and Ben Konyi's PR strips synthetic 'type' and 'method' fields from service extension responses [10]. Apple's distributed runtime is getting validation hardening [11], and cxx-interop now honors libkern's return ownership attributes [12]. It's a busy 94 commits and 61 PRs.

Action items

→ Audit Swift runtime consumers for SWIFT_* env var reliance; update if you run setuid or hardened binaries apple/swift [immediate]
→ Plan to drop Gradle 8.13 and older from Kotlin build matrix JetBrains/kotlin [plan]
→ Monitor Flutter's Windows tooling fixes if you hit UNC path or wrap-column issues flutter/flutter [monitor]
