Our CI runner is a bare-metal dedicated server with an AMD Epyc 7413 24c/48t 2.65/3.6 GH, 128 GB ECC 3200 Mhz RAM and NVMe SSD.
I have just configured a Mac mini M4 24GB as runner for Xcode builds.
Just for kicks, I also activated a docker runner on the Mac mini and handed it a random job.
That job takes an average of 4m40s to run on the AMD server.
It took 1m20s to run on the M4 Mac mini.

Are you interested in finding the SwiftUI views in your app that update the most? The following article shows how to use the SwiftUI instrument to find the views that update the most:

I should try to get a #FuckingXcode tag going. Because fucking #Xcode.
Run a test suite, all the tests get green checkmarks next to them. Then write a test that fails. To debug the test, run just that one test. All checkmarks remain while you run that one test, despite others not running. If you break another test, it looks like it still passes. If you use cmd-opt-ctrl-g to rerun the last test set run, it LOOKS like they all pass, but they don't. Xcode keeps stale pass icons instead of removing or greying them out. If don't remember you're not running the entire suite… ¯\_(ツ)_/¯
Fucking Xcode.
In #Xcode, is there a way to configure how the debugger shows a type of variable?
Specifically, I'm using `Duration`, which is basically unreadable in the variables panel. However, I created an extension for Duration that adds a ` timeInterval` property that returns a TimeInterval (which is a type alias for Double).
How do I get Xcode to always render Duration using the `timeInterval` property I added to it?
[Edit] IntelliJ IDEA calls this “Java Type Renderers”, so if you know what that is that's basically what I'm looking for.
Apple, please fix medianalysisd CPU eater in simulator 😭
This makes your simulators (along with Xcode previews or even interface builder) to eat all your cores for many minutes - consuming tons of energy.
What this even analyze inside simulators? Is it a bug? It was introduced somewhere in #Xcode 26.4 or .3 but still is present in 26.5 😌
