For the test, I decided to use an app that I actually work on: eidolon. Unlike most iOS apps, the project is stable and not under active development, so it's a prime candidate for accurate-ish benchmarking.
For "fresh" builds, I cleaned the build folder (⌘⇧K) repeatedly until it worked with no permissions problems. Then I sat and waited for Xcode to index the project. I also made sure the simulator (iPad Air 2) was closed, so these times include booting the simulator and launching the app. Each version of Xcode above should use the latest iOS version that it ships with. Then I hit ⌘R and start a timer, only ending it when the app had fully launched.
"Incremental" builds represent a more common use case: changing one file and recompiling with the simulator already running. I added print("hello!") to application(: didFinishLaunchingWithOptions:) and hit ⌘R, timing the time it took for the app to launch.
I repeated each test a few times and took their average times.
It would be super-cool if we could perform the above tests on a variety of machines and consolidate the results here. Below are the instructions to download the code (compatible with Apple Silicon thanks to @pawelurb), and send a pull request adding your own results. I'd super-appreciate it! 🙇
This repository is deprecated, but the results will stay around for posterity. See below for more.

This repository was created in 2015 when I worked at Artsy. The main project I worked on at the time (Eidolon) was open source, making it an ideal test case for measuring Xcode compile times of real-world apps. However, I stopped working at Artsy in 2021 and Artsy is no longer maintaining Eidolon for compatibility with the latest versions of Swift, Xcode, CocoaPods, and open source dependencies.
I could continue maintaining the repo for Artsy, since Eidolon remains open source, but honestly, keeping this Xcode benchmarking repo maintained is a lot of work, and a better repository exists.
So at the end of 2021, I'm deprecating this repository. It was a hell of a ride. I'm grateful to Artsy for the opportunity to leverage their code for the good of the iOS developer community. And I'm most grateful to dozens of contributors who made this a valuable resource. Thank you, everyone.
