I am using Mac OS in VMWare for iOS app development.
After updating the OS and Xcode, the iOS device isn\'t available so I cannot test it.
When the device is
I have 2 computers with VMWare Workstation and Mac OS Sierra installed as the guest OS. First machine could recognize my iOS device whereas my second machine could not recognize it. The second machine was exhibiting the same behavior as others reported where it would reconnect and disconnect with the iPhone endlessly.
Thankfully, my second machine had network connectivity problems with my VM. So I stumbled upon the solution when I reset my network settings for the VM.
You can try the following steps and see if it works for you. It worked for me.
