Aoife McLaughlin prepared the guardian/source-apps repository for future cross-platform development by implementing conditional compilation to gate iOS-specific UI components, ensuring that these elements are only included when building for iOS. Using Swift and SwiftUI within Xcode, Aoife updated the macOS deployment target to version 15.0, aligning the project’s configuration with the broader goal of multi-platform support. This foundational work reduces the risk of platform-specific issues and minimizes future refactoring effort as the codebase evolves. While no bugs were fixed during this period, the changes established a maintainable structure that accelerates the roadmap toward UI parity across Apple platforms.
