Xcode 10.1 beta cannot connect to iPhone XS

When connecting the new iPhone XS a poppup appears "A software update is required to connect to your iOS device"


After clicking install a "downloading" window comes up for a while followed by


"Installation failed

Can't install the software because it is not currently avaliable from the Software Update Server."

Which version of XCode ?
