The article details how the author used LLMs to solve a decade-old bug in a music streaming app that used a unique Swift/C++ cross-platform architecture. The bug was related to offline song storage functionality that had persisted through multiple platform migrations. The solution involved analyzing a complex tech stack including Djinni, Carthage, and custom C++/Swift interoperability layers.
Background
The article discusses a complex cross-platform mobile app architecture that combined Swift/Objective-C for UI and C++ for business logic, using the Djinni framework. This setup, while powerful, created challenging debugging scenarios that persisted for years until modern LLM tools helped resolve them.
