Showing error in Swift5 Generator

This project showcases a weird error where callback closure is not called.

• This happens with the default library selected (URLSession). With Alamofire, everything is fine.
• In the 5.0.0 stable version, the error is not happening
• Snapshot Commit: 90ed1290fafe08306283f9acb74650e5b8d19302 from 2020-01-22
• Tested with Xcode 12.3 (12C33) on macOS Catalina 10.15.7 (19H15)
• Try switching the generator from snapshot to stable pod in Podfile to see the change.

Debugging

• The issue seems to be in URLSessionImplementations.swift in line 137. self seems to be deallocated immediately, because it’s weak.
• When I remove [weak self] it works again. But this isn’t the root of the problem, since the stable version also has [weak self]
