Flutter is migrating away from deprecated strict analysis modes in favor of lint rules, while Swift patches critical crashes in bit-field accessors and C interoperability.

Flutter shipped a significant cleanup across its analysis pipeline [1], replacing deprecated strict analysis modes with lint rules to align with Dart SDK direction and reduce technical debt. This is foundational work that affects how developers write and validate Flutter code going forward. On the Swift side, the compiler team fixed a crash in C++ interoperability when handling bit-field accessors [2], which was tripping Clang's constant evaluator and taking down swift-frontend. They also expanded C-interop support to handle Objective-C type metatypes through @c declarations [3], closing a gap where ClangImporter could read 'Class' types but C-interop functions couldn't use them. A separate fix addresses backtracing infrastructure [4] by marking friendly backtrace tests unsupported under remote-run, acknowledging that DWARF absolute paths don't translate across machines. String bridging tests also got corrected in use_os_stdlib mode [5], fixing a compatibility edge case.

Action items

→ Review Flutter lint rules in your project as strict analysis modes are phased out flutter/flutter [plan]
→ If using Swift C++ interoperability, pull the latest toolchain to avoid bit-field crashes apple/swift [immediate]
→ Monitor Swift C-interop PRs if you're bridging Objective-C Class types apple/swift [monitor]
