I am a new learner and trying to build my first app is I learned from "Develop in Swift Fundamentals with Xcode 11. I have installed Xcode 11.5 on MacBook Pro (mid-2012), running macOS 10.15.7. I tried to build first app "GettingStarted" that builds successfully but shows the error message as below. "FailedToConnectToDTServiceHubError: Cannot connect to Dr. Farooq Try disconnecting and reconnecting the device. Dr. Farooq"

I tried with Xcode 11.7 first but got the same message, then I installed Xcode 11.5, but still I am getting the same error. Can someone help me on this issue, although small for the experts.

Does it run on simulator ?

When you connect the iPhone with UISB and open the Window > Devices and simulators, do you see the iPhone in Device list ?

What is iOS version on device ?

You can try to reboot both Mac and iPhone.

Hi, Claude31, Thank you very much. I finally discovered that my iPhone is running iOS 15, which is not compatible with Xcode 11. Thanks again for your help.
