Over the course of this summer, I had the opportunity to participate in the Google Summer of Code at Swift. I implemented a new Swift library within the swift-syntax package: SwiftLexicalLookup. The library consists of various lexical queries and, most importantly, implements the new unqualified lookup API that, in the long run, is supposed to replace the current implementation within the compiler. This post summarizes my GSoC experience, briefly describes the new library, and discusses its future.
