• ✓Ecosystem Steering Group core team representative
• ✓Website and Contributor Experience Workgroups

Why we celebrate them. Mishal keeps the machinery of the Swift project itself running: the CI, the releases, the website, the contributor experience. It is thankless infrastructure work that every single Swift toolchain download depends on, and he has done it for years with quiet excellence.

Dave Lee

Swift debugging engineer on LLDB at Apple

• ✓Debugging Improvements in Swift 5.9
• ✓LLDB Swift language support
• ✓Advanced debugging talks and lldb helpers

Why we celebrate them. Dave makes the moments when your code is broken less painful, improving how LLDB understands Swift and sharing practical debugging techniques with the community. His Swift 5.9 debugger improvements like the new p and po implementations touched every Xcode user.

Egor Zhdan

Swift and C++ interoperability engineer at Apple

• ✓C++ Interoperability Workgroup
• ✓std::string and std::vector import support
• ✓LLVM developer meeting talks on Swift C++ interop

Why we celebrate them. Egor is one of the engineers who taught Swift and C++ to speak to each other, importing the C++ standard library so decades of existing code can be reached safely from Swift. His workgroup participation kept the effort open and community-driven from day one.

Zoe Carver

Swift and C++ interop pioneer

• ✓C++ Interoperability Vision Document
• ✓Swift C++ interop compiler work
• ✓libc++ contributions

Why we celebrate them. Zoe started leading Swift's C++ interoperability effort while still in high school and carried it all the way to a WWDC23 keynote feature. That arc, from open source volunteer to shaping a flagship language capability, is one of the great stories of the Swift project.

Gábor Horváth

Compiler engineer on Swift and C++ interop safety

• ✓Safe C and C++ interop mode in Swift 6.2
• ✓Clang maintainer for static analysis
• ✓EuroLLVM talks on interop with memory-safe languages

Why we celebrate them. Gabor works on the hard question of how Swift can borrow C++ code without inheriting its unsafety, helping ship the safe interop mode with bounds-checked span support. His Clang static analysis background makes him exactly the right person guarding that boundary.
