Harlan Haskins is a seasoned software engineer with 13 years of experience focused on Apple platforms, currently building augmented reality frameworks at Apple in New York. A longtime Swift advocate and former member of the Swift compiler team, he contributes across compiler internals, tooling (SwiftPM, swift-driver), and debugger integrations (swift-lldb). Harlan blends systems-level backend work—refactoring Clang/clang-related FileManager code and improving error handling—with polished iOS UI contributions like BRYXBanner and JSQMessages enhancements. His open-source track record shows deep attention to robustness and developer ergonomics, from diagnostics in SwiftSyntax to safe shell-escaping and linking in the driver. He’s active on GitHub and Twitter as @harlanhaskins and brings a practical, compiler-to-UI perspective rooted in a CS degree from RIT.
