Worked on stabilizing cross-platform XCFramework builds in the tuist/tuist repository by implementing platform slice handling for device and simulator builds. Addressed the challenge of ensuring all relevant platform slices were included in FRAMEWORK_SEARCH_PATHS, which allowed both device and simulator builds to resolve the correct binaries and reduced build-time errors. This technical approach improved continuous integration reliability and minimized post-merge regressions for multi-platform XCFramework usage. The work involved collaborative problem-solving on issue #9730 and required proficiency in Swift, Xcode, and iOS development. The contribution focused on enhancing developer experience and maintaining robust build processes across platforms.
