Issue Description:

I have a UITableViewController subclass which has a @published property. This class override the `func tableView(_:didSelectRowAt🙂` method and set a value of the @published property in this method.

This scenario makes the Swift compiler to crash with `Segmentation fault: 11`

I attached a reproducible project
