Polymorphic methods in enums This is an interesting discussion on the official Swift forums. It was started by Pablo Bendersky who would like to be able to add extensions on enums constrained by the enum case. I can see the value in this. Posted on August 13, 2018 #polymorphic #enum
Migrating an Objective-C class to Swift: a piecemeal approach Migrating legacy Objective-C code to Swift can be an arduous process, and is often done as part of general code maintenance over a long period of time. In this post, Ole Begemann presents a piecemeal approach to such a migration, and provides a solution for a particular roadblock he encountered.

Where usage in Swift Antoine van der Lee presents examples of how and when we can use the where clause in Swift to easily filter values. Posted on August 10, 2018 #where
Synthesized Conformance to Equatable Greg Heo looks behind the curtain to show us how the Swift compiler automatically synthesizes conformance to the Equatable protocol. Greg starts by describing how the compiler decides is conformance is possible, before looking at how it generates the code. Posted on August 9, 2018 #equatable #c++
Conditional Compilation in Swift, Part 1 Dave Delong has developed his own way of conditionalizing compilation of Swift code when using Xcode. Dave shows us how we can use configuration files settings together with certain build settings to conditionally compile code based on the platform being targeted.

Never Mattt Thompson from NSHipster looks at Never, a simple, uninhabited Swift type. Mattt first explains uninhabited types before demonstrating how we can use Never to eliminate states. Posted on August 7, 2018 #never
Structuring Swift code In this post John Sundell offers his advice on how we can structure our Swift projects in a solid and consistent manner, making them easier to navigate for existing and new team members. Posted on August 6, 2018 #structure #organization
Swift tip: Building arrays with compactMap Jesse Squires demonstrates how we can use the Swift compactMap function to build arrays of optional items, while maintaining the intended order of the items. Posted on August 3, 2018 #compactMap #filter #array
Benchmarking Swift Locking APIs This is a really interesting post from Vadim Bulavin in which he benchmarks Swift locking APIs. While the results are not entirely surprising, I was surprised by how bad one particular API performed. Posted on August 2, 2018 #benchmark #locking #async
