During March 2026, Alex contributed to the tuist/tuist repository by developing a feature that stabilized cross-platform XCFramework builds. He addressed the challenge of ensuring both device and simulator builds could reliably access the correct binaries by implementing platform slice handling and updating FRAMEWORK_SEARCH_PATHS to include all relevant slices. This technical approach reduced build-time errors and minimized post-merge regressions, directly improving CI reliability and the overall developer experience. Alex’s work required in-depth knowledge of Swift, Xcode, and iOS development, and demonstrated collaborative problem-solving through co-authoring a coordinated fix for issue #9730 within the project’s codebase.
