The Swift type checker is a crucial component of the Swift compiler, responsible for ensuring that code is type-safe and free from errors. However, the type checker can be slow and inefficient in certain situations, leading to performance issues and code compilation delays. To address these challenges, the Swift team has outlined a roadmap for improving the type checker, which includes short-term and long-term goals, as well as future improvements. In this article, we will explore the roadmap, its goals, and the planned improvements to the Swift type checker.
