Rockstar🎓
Top SchoolStuart Montgomery is a Swift testing frameworks engineering manager with 14 years at Apple, now leading the Swift testing team from Austin after a progression through XCTest, iOS Phone/FaceTime, and build engineering roles. He specializes in test automation and QA for Swift, contributing notably to the open-source swift-corelibs-xctest project where he enhanced asynchronous testing, added XCTWaiter functionality, and improved test skipping and expectation handling. His career blends deep platform-level engineering with developer tooling and build systems, giving him a rare end-to-end perspective on shipping reliable systems for large-scale consumer software. Colleagues rely on him for pragmatic API redesigns that balance backward compatibility with modern async patterns. He holds a BS in Computer Science from the University of Texas at Austin and brings both hands-on coding and people leadership to complex testing and developer-experience challenges. An understated but consistent thread in his work is improving testability of core libraries so engineers can deliver features faster with higher confidence.
