Cannot run Xcode (7.3) UI tests in Jenkins

I am trying to run Xcode UI tests from command line on a Jenkins machine that work on my local computer. However, when I try to run the UI tests in Jenkins, they appear to fail to launch the app in the simulator. What happens is the device loads in the simulator, the UI test target opens, and the screen goes black. Then nothing seems to happen for 30 seconds until I get an error as follows (I expect the app to launch and the automation to begin):

Could the app be failed to start because my Jenkins machine can't open it fast enough before Xcode implicitly fails the test? Or could there be a notification that is blocking the app from launching?

What happens is that XCTest tries to send Home button press event to the device, but does not receive notification for completion for 30 seconds.

I don't think it has anything to do with a notification UIAlertView blocking the Home button from sending the testing target to the background, since in my experience such problem raises a different error message ("Failed to background test runner within ...").

I am not familiar with the Jenkins solution, but if you suspect the timeout to be too short, you can try changing it as follows (some hacky way I found).

Add the following lines to a code that will run earlier then [XCTestDriver _runSuite] (for instance, add your own __attribute__((constructor)) function and put this code inside):

extern __attribute__((weak)) void* _XCTSetEventConfirmationTimeout(NSTimeInterval);
// Change the default 30 seconds timeout.
long MY_NEW_EC_TIMEOUT = 120;
NSLog(@"Trying to call _XCTSetEventConfirmationTimeout(%ld)", MY_NEW_EC_TIMEOUT);
if (&_XCTSetEventConfirmationTimeout) {
    NSLog(@"_XCTSetEventConfirmationTimeout address found");
    _XCTSetEventConfirmationTimeout(MY_NEW_EC_TIMEOUT);
    NSLog(@"_XCTSetEventConfirmationTimeout successfully called");
} else {
    NSLog(@"_XCTSetEventConfirmationTimeout address not found");
}
