Xcode 8 cannot support if you do not have a DeviceSupport folder for iOS 11.

• You can download Xcode 9 beta (the latest Xcode 9) or get the DeviceSupport folder from another user.

• Just copy it to a folder or create a symbolic link

sudo ln -s /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/11.0\ \(15A372\) /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/11.0

Answer 3

I did this, and everything is fine, I still work in a commercial application using Xcode 8 + Swift 3, and in search of Xcode 9 beta with Swift 4. Just download Xcode 9 and using the Xcode 8 settings, install the command line tools use 9.0.

Answer 4

I preferred to copy the ALL folder:

 /Volumes/**HighSierra**/Applications/Xcode-**beta.app**/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/11.0\ \(15A5278f\) 

at

  /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/**11** 

I can confirm that I can work on my iPhone 7 with iOS 11
