We describe a new LLVM frontend for Infer, specifically for Swift analysis. This project is vital due to Swift’s increasing use in Meta’s iOS applications, with the primary goal of identifying critical issues such as retain cycles and null pointer crashes at the Objective-C and Swift boundary. We cover some highlights of the implementation of the frontend, including the translation of virtual calls and the mapping of LLVM’s memory model to Pulse’s abstract heap. Challenges like opaque pointers are discussed, alongside the comprehensive testing infrastructure established for validation. The work ultimately aims to contribute to more robust and reliable Swift applications by enhancing Infer’s capabilities in detecting memory safety issues for Swift.
