Use Xcode 8 with iOS 11

Question

I want to use Xcode 8 with iOS 11.

should I upgrade my Xcode. However, my code can\'t be built by the new compiler, so I want to stay with Xcode 8.

Answer 1

I preferred to copy ALL the folder:

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

to:

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

I can confirm I can run on my iPhone 7 with iOS 11
