Xcode 9 supports not only Swift 4, but a transitional version 3/2 as well, so your project should compile without any harsh difficulties.

You can specify different Swift versions (https://longthanhtourist.com/content/uploads/files/download/new-version-of-swift-key-apk.zip) per target, this is very helpful if some third-party libraries didn't update yet or if you have multiple targets in your project.
