This shows significant improvement from Mojave, Xcode 10 build times on the same hardware: Clean build 0:40, incremental 0:13 see https://github.com/ashfurrow/xcode-hardware-performance/pull/94/files

and new Mac Pro 2019 3.2 GHz 16-Core Xeon so not worth it, showing: Clean build 0:40, incremental 0:06 see https://github.com/ashfurrow/xcode-hardware-performance/pull/111/files

@paulz , do all these build times include launching the simulator and waiting until the app has launched?

paulz commented 4 years ago

Good point @beeradmoore, I was measuring just build time without the time of launching the simulator app and launching the app.

Now with the Launching app adds 10 seconds to the incremental build! And 6 seconds to the clean build 47 seconds and 12 seconds

Launching app and simulator (iPad Pro iOS 13.3, an iPad Air 2 is only iOS 12.2) adds another 10 seconds 57 seconds and 22 seconds

Also, I am not seeing the Xcode reindexing project after cleaning the build folder, as mentioned here: https://github.com/ashfurrow/xcode-hardware-performance/blame/master/Readme.md#L138

@paulz Thanks for the contribution! Are the current results in the pull request representative of launching the simulator as well? In other words, is this good to merge?

paulz commented 4 years ago

Updated the stats to include simulator launch and app startup. Ready to merge! Thank you for maintaining the metrics, @ashfurrow
