Friday Q&A 2017-09-22: Swift 4 Weak References
Read OriginalThis technical article by Mike Ash details how weak references are implemented in Swift 4, contrasting it with the older Swift implementation. It covers the flaws of the old system (like zombie objects and thread-safety issues) and describes the new object data layout, including reference counts and auxiliary runtime information. It's a deep dive for developers interested in Swift's memory management internals.
