Xcode 10.1 and libimobiledevice issue for IOS physical devices

I have installed Xcode 9.2, appium 1.7.2 and dependencies like libimobiledevice and etc.,. It is working fine and i can run the automation upto 11.2 IOS version physical devices. But, when I try the same with Xcode 10.1 and latest libimobiledevice in Mac Os 10.13.6, But I am getting error either confitest access denied while doing the installation or getting lockdownd error code -21 when running the ios_webkit_debug_proxy. Please give your input, Thanks in advance.

I googled the above and saw a lot of chatter about this issue:

This one is specific to libmobiledevice. Perhaps it’s your issue?
