Description ADKaster opened on Aug 2, 2024 Issue body actions List of issues preventing moving forward on moving Swift 6.0 support out of an experimental state: Swift issues: Please backport d8352e93c1c8042d9166eab3d76d6c07ef585b6d swiftlang/llvm-project#8998 Details: Swift’s version of LLVM is missing the fix for [Clang] ICE in CheckPointerToMemberOperands passing decltype of lambda llvm/llvm-project#53815 . This means that any assertions build of llvm from the swift open source project cannot build our code. Snapshot builds are released with assertions on. Workaround: Build swift from source on Linux without llvm assertions, or use macOS. PR: 🍒 [Clang] [Sema] Handle placeholders in ‘.*’ expressions (#83103) swiftlang/llvm-project#9038 Fixed in Swift 6.0.0 release Interop: Compiler and C++ Bridging header disagree on ABI of Optional swiftlang/swift#75593 Details: It is not currently possible to return a swift optional of a small C++ type back to C++. The compiler and the generated bridging header disagree on how that is supposed to be done. Workaround: Don’t use Optional, use a return type that forces the C++ type to be heap allocated. Array is one alternative. Interop: Compiling with C++17 or higher on Ubuntu 22.04 fails with cyclic header dependencies in libstdc++ swiftlang/swift#75661 Details: Swift’s clang module map for libstdc++ contains cycles when is included. See https://forums.swift.org/t/swift-5-9-release-on-ubuntu-22-04-fails-to-build-std-module/67659 Workaround: Edit /lib/swift/linux/libstdcxx.h to comment out the #include line. PR: [cxx-interop] Disable c++ execution header with libstdcxx versions >= 11 swiftlang/swift#75662 (Just a workaround, not a fix) 6.0 Backport: 🍒 [cxx-interop] Disable c++ execution header with libstdcxx versions >= 11 swiftlang/swift#75971 Fixed in swiftlang/swift:main and release/6.0, but not in 6.0.0 or 6.0.1 Interop: Cannot return swift::Optional from C++ function swiftlang/swift#76024 Details: Returning binding types swift::Optional or swift::String from a C++ function is not supported Workaround: Return std:: types? Swift cannot import libstdc++-13 chrono header in C++23 mode swiftlang/swift#76809 Details: Swift 6.0 cannot import
