mostly this error comes This is another error that comes frequently Hi, after updating to xcode 10.2.1 simulators are not working.My using mscOS Mojave Version 10.14.4 in my Mac mini (Late 2012). The Simulators takes 20-30mins to attach the apps and after waiting for that much it gives error messages like "could not attach to pid:980","could not attach to pid:1020", "DTServiceHubClient failed to bless service hub for simulator". After this error message system starts lagging, performance slows down drastically.



I tried everything, Cleaning build folder, resetting simulator, reinstall xcode, updated mac OS, checked the host.txt file it includes localhost line, ping is also right. Please help me I have no idea what to do.
