After upgrading to stack to osx-xcode-15.0.x
Our projects unit test time increases 5x (~60 mins) compared to Xcode 14 stack (~15 min)
We are unable to reproduce this on our mac (M1 Pro), unit tests runs smoothly on our side with same Xcode version
Haven’t been able to create a project to reproduce this issue yet, but my friend who is also using Bitrise Xcode 15 stack is also having this issue.
I have found that changing the Preferred Capture Format on your test plan from video to screenshot make it faster. Still not as quick but I managed to get a full run of ci without timing out.
Our build+test times have increased from 4-5 minutes to 7-12 minutes. One thing I noticed was that the default “-destination” device in Bitrise was “iPhone 8 Plus”, which doesn’t work with iOS17 builds, so I had to change it. I arbitrarily decided on “iPhone 14”, and I’m wondering if that is part of the reason for increased build times?
I expect this problem will be fixed in Xcode 15.0.1
Fixed: Executing Unit/UI tests from Xcode on the iOS Simulator takes an extended time to launch on first run of the suite. (115187363) (110330776) (FB12237092)
