Use Xcode 8 with iOS 11
As of now this is only for Debugging on iOS device, not Simulator
Xcode 8 could not support unless you have the DeviceSupport folder for the iOS 11 version.
You can download a Xcode 9 beta (latest Xcode 9) or get an DeviceSupport folder from other user.
Simply copy it to your folder or create an symbolic link
