Query: “What are the most common pain points with Swift for developers in 2025?”4/4/2026

Build times on Linux when using the new Foundation are quite painful (we need to not only build swift-foundation, but also swift-syntax due to use of macros - it's a well-known problem of course, but just wanted to mention it as it causes long CI turnaround for us).
