I'm procrastinating on HN right now because my iOS build time is 2 and a half minutes long. About 30-50 seconds on an incremental build. This is true suffering. Oh wanted to update with Specs;

Running SwiftLint or SwiftFormat in a build phase killed my compile times (SwiftLint especially). It'll help a lot to run them manually or with a git pre-commit hook.

I know Swift had really bad compile times for awhile, but anymore I think it's pretty fast. I've moved all my WIP stuff into a single project (113 Swift files, ~5,500 LOC) for my convenience, and incremental builds are around 3 seconds on a 2015 MBPr.
This article shows some flags you can use to find code that is slow for the compiler to deal with: https://www.avanderlee.com/optimization/analysing-build-perf...
