This SPM package contains a very basic implementation of a generic Stack<Element> type that has value semantics and uses copy-on-write (COW) to improve its performance.
Therefore, it works similarly to the collection types from Swift's standard library (e.g., Array<Element>, Set<Element>, String).
There is an accompanying blog post for this repository: https://tonisuter.com/blog/2020/01/understanding-copy-on-write-value-types-swift/
This repository was only created to demonstrate Swift's copy-on-write mechanism with an example. It has various limitations and is not supposed to be used in production. If you ever want or need to create a Stack type you should probably just wrap a regular Swift array (or use the array directly).
