I've tried manually updating the example version myself (duplicating the project, linking to the swift-10.2.1 RealmSwift framework, and updating the Swift version to 4.2.1 in all projects' Build Settings), however this causes a different issue:
Module compiled with Swift 4.2.1 cannot be imported by the Swift 5.0.1 compiler

I don't believe this is still an issue.
