Jenkins running xcode unit tests not working - xcode

Question

I'm trying to configure CI with Jenkins for Xcode. I'm getting the following error in the console. The tests are running and I get a test output with JUnit. However it still says that it cannot runscripts.

EDIT
The following error is given from running unit tests on command line in addition to the above error:
Session could not be started: Error Domain=DTiPhoneSimulatorErrorDomain Code=2 "Simulator session timed out." UserInfo=0x7fb9d35003a0 {NSLocalizedDescription=Simulator session timed out.}
The script for the unit tests that I am running is:
#!/usr/bin/env ruby
if ENV['SL_RUN_UNIT_TESTS'] then
launcher_path = "ios-sim"
test_bundle_path= File.join(ENV['BUILT_PRODUCTS_DIR'], "#{ENV['PRODUCT_NAME']}.#{ENV['WRAPPER_EXTENSION']}")
environment = {
'DYLD_INSERT_LIBRARIES' => "/../../Library/PrivateFrameworks/IDEBundleInjection.framework/IDEBundleInjection",
'XCInjectBundle' => test_bundle_path,
'XCInjectBundleInto' => ENV["TEST_HOST"]
}
environment_args = environment.collect { |key, value| "--setenv #{key}=\"#{value}\""}.join(" ")
app_test_host = File.dirname(ENV["TEST_HOST"])
passed = system("#{launcher_path} launch \"#{app_test_host}\" #{environment_args} --args -SenTest All #{test_bundle_path}")
exit(1) if !passed
exit 0
else
puts "SL_RUN_UNIT_TESTS not set - Did not run unit tests!"
exit 0
end
Please help me out.
Thanks!
