We recently upgraded our CI from Xcode 15.3 to Xcode 16 and now use the iOS 18 simulator to run our unit tests. We are seeing a large performance regression in our test times (takes twice the time as before).
I noticed a lot of CPU consumption related to the iOS simulator image that I didn’t observe with Xcode 15.3.
I checked also if the issue is specific to the iOS 18 simulator but it also happens when running with iOS 17.5 under Xcode 16.
Any ideas how to work around this?
