Build Time Analyzer is a macOS app that shows you a break down of Swift build times. See this post and this post on Medium for context.
Open up the app and follow the instructions.
Download the code and open it in Xcode, archive the project and export the build. Easy, right?
If you are on Xcode 7, instead use the Xcode plug-in.
If you encounter any issues or have ideas for improvement, I am open to code contributions.
