+# [Lazy Containers](https://github.com/RougeWare/Swift-Lazy-Patterns) #
+A few ways to have a lazily-initialized value in Swift 5.1. Note that, if you are OK with the behavior of Swift's `lazy` keyword, you should use that. This is for [those who want very specific behaviors](https://stackoverflow.com/a/40847994/3939277):
+
+ * [`Lazy`](https://github.com/RougeWare/Swift-Lazy-Patterns/blob/master/Lazy.swift#L184-L248): A non-resettable lazy pattern, to guarantee lazy behavior across Swift language versions
+ * [`ResettableLazy`](https://github.com/RougeWare/Swift-Lazy-Patterns/blob/master/Lazy.swift#L252-L330): A resettable lazy pattern, whose value is generated and cached only when first needed, and can be destroyed when no longer needed.
+ * [`FunctionalLazy`](https://github.com/RougeWare/Swift-Lazy-Patterns/blob/master/Lazy.swift#L334-L444): An idea about how to approach the lazy pattern by using functions instead of branches.
