Xcode 8 on High Sierra (10.13.1)

Good afternoon. I updated my mac to the latest OS, but did not take into account one point, namely the version of the icon code of their compatibility with macOS. Initially, I needed this particular mac to work in xcode with the SDK for iOS 10.3 and swift 3 versions. But so I did not take into account that high sierra is now in the AppStore only with xcode 9, it is with the SDK for iOS 11, and fully works only with swift 4. So now there are two ways out: 1) Is it possible to run in xcode 8.3.3 on 10.13.1? The xcode app itself runs, but will the whole thing work correctly? I understand that there are some components that need to be manually tightened, at least (up to this point, I put xcode only from the App Store). I haven't worked particularly in xcode before, so I don't know what the difficulties might be in this case. 2) Roll back to 10.9.5 from the time machine from a fresh backup and from there it will be updated (without data loss) to 10.12, on which there will definitely be no problems with xcode 8.
