If you are worried, make a copy of your current Xcode before you get 9.0.1. Different versions of Xcode can happily live side by side: an install of Xcode is completely self-contained. You will only have problems going back to an earlier version if you make new API calls or you use Swift 4. Unchanged projects can be compiled by 9.0.1 and, if that fails for some reason, you can go back to the previous version.
