Memory management scares most developers when it doesnât work as expected. Appleâs Automatic Reference Counting (ARC) magically handles most memory management we used to do manually, but still often needs guidance to work well. Swift provides us with cool tools like capture lists, unowned, and weak references to do so. In this talk, Hector Matos discusses memory leaks and retain cycles â how these

Swift is now open source. For the latest news, visit the Swift open source blog Like many other languages, Swift allows a class to override methods and properties declared in its superclasses. This means that the program has to determine at runtime which method or property is being referred to and then perform an indirect call or indirect access. This technique, called dynamic dispatch, increases

I spent most of my free time last weekend and a few days of last week on migrating my Swift code to Swift 3.0 â I migrated my open source projects as well as my private side projects.

It definitely could have been better, but I think the largest problem was overcoming the cognitive hurdle of seeing all the changes and errors from Xcodeâs migration tool

1) Allow two Cacheables of the same type to be compare protocol Cacheable: Equatable { //....// func identifier() -> String } func ==<T : Cacheable>(lhs: T, rhs: T) -> Bool { return lhs.identifier() == rhs.identifier() } Pros This is the simplest solution. Cons You can only compare two Cacheable objects of the same type. This means that code below will fail and in order to fix it you need to make
