Failed to initiate service connection to simulator

DTServiceHubClient failed to bless service hub for simulator iPhone 8 (81F102A0-7BDB-4A51-903B-CBC4AFFF93FB)

Same issue in Xcode 10 when trying to use **any** simulator that is setup for iOS 12: iPhone XS, iPhone XR, iPhone XS Max, and any older iOS device configured for iOS 12. — Cerniuk, Sep 29 '18 at 15:15
@WilliamCerniuk right dear, Apple should resolve in upcoming versions! — Xcodian Solangi, Oct 01 '18 at 04:43
In my case, App was installed in the device, so I uninstalled my app and run the build again, it works. — satuser, Jan 14 '20 at 07:10

Just clean & build yor project it will run fine. If it does not help, then restart the xcode, clean & build the project.

iOS simulators using iOS 12 still stall for me under Xcode 10 / Mojave – Cerniuk Sep 29 '18 at 15:15
@WilliamCerniuk right dear, Apple should resolve in upcoming versions! or they should give us suggestion to resolve issues in pop up box – Xcodian Solangi Oct 01 '18 at 04:45
macOS 10.14.3 (18D109), ios simulator 12.1. All common fixes for this don't work. I even rm -fr the simulators and recreated them... – Thom Mar 05 '19 at 12:57
Restarting Xcode alone was sufficient to fix the error for me. – Eliot Dec 18 '19 at 01:07

The only thing that worked for me was to restart my computer.

Clean build, xcode restart, simulator restart, simulator erase content and settings... did not help.
