I am running my UI Tests on Github CI and the tests are flaky. I don't understand how I can fix it. The animations are disabled and I am running the tests on a iPhone 13 plus. A lot of tests are running green, but some are not working. Locally, I got everything working.
These are some logs:
2022-06-21T13:42:23.2627250Z t = 63.34s Tap Cell
2022-06-21T13:42:23.2707530Z t = 63.34s Wait for com.project.project to idle

2022-06-21T13:42:24.2022460Z /Users/runner/work/project/UITestCase.swift:665: error: -[project.UserTagTest testTapInTextView] : Failed to get matching snapshot: Lost connection to the application (pid 12676). (Underlying Error: Couldn’t communicate with a helper application. Try your operation again. If that fails, quit and relaunch the application and try again. The connection to service created from an endpoint was invalidated: failed to check-in, peer may have been unloaded: mach_error=10000003.)
It can not find the cell because of these logs:
Unable to monitor event loop
Unable to monitor animations
I know this because I sometimes get different errors than the error above, which says that the connection to the application is lost, right below the Unable to monitor... error logging.
Is there anything I can try? I don't have a reproduction project. This is the command that is executed:
xcodebuild test -project project.xcodeproj -scheme project-iosUITests -destination 'platform=iOS Simulator,name=iPhone 13 Pro,OS=15.5'
The CI runs 35 tests and 5 fails randomly with the Unable to errors. Is there any suggestion to fix this problem?
