It's decidedly not free. Reference counting in Swift can be (is?) a major bottleneck. See this project: https://github.com/ixy-languages/ixy-languages and its discussion on Swift performance: https://github.com/ixy-languages/ixy.swift/blob/master/perfo...

It’s free since the language is already using reference counting. But yes, retain/release traffic is often a huge problem in performance-critical code.
