There are hundreds of complex routing frameworks and libraries in iOS. Usually they’re overly complex to retrofit into an existing app or they completely bypass Storyboards. In this post, I’d like to offer a simple, native-like routing mechanism that leverages Storyboards like a boss to handle navigation.
Localization in Xcode is handled with NSLocalizedString, but it is such a verbose and legacy-like API. There’s a Swiftier way that still respects Xcode .xliff exports and comments.
Let’s use the closure-based pattern to wrap CLLocationManager for allowing callers to subscribe to observables instead of using shared delegate functions.
Delegation is a simple and powerful pattern. However, closures are more Swifty and scales better. Let’s convert delegates to closures!
Thread-safe resources in Swift can be achieved with Grand Central Dispatch. Using a concurrent queue and the barrier flag, reads can occur in parallel while writes are given mutual exclusivity for safety and optimization.
GCD is not for thread-unsafe shared resources since it does not guarantee the same thread will be used for the queue. We can use the threads API with a bit of sugar syntax.
WordPress has been around for almost a decade and a half. It survived the CMS wars and remained relevant during the mobile shift. It’s been battle-tested under various scenarios and load. It showed us what a thriving 3rd party marketplace looks like. Now, WordPress is realizing a grander vision! In the release of WordPress 4.7, the REST API plugin was merged […]
Grand Central Dispatch (GCD) is a great technology provided by Apple. It provides an elegant level of abstraction to work with threads, queues, and locks. And it went through a much needed make-over in Swift 3. In this post, I would like to take this one step further using enums as a queue factory.
Swift initialization rules are there for very good reasons, but sometimes it can make things tedious. In this post, I will show how to avoid duplicating code across initializers while still obey Swift initialization rules. This pattern uses static functions, tuples, and typealiasing.
Less code and less memory while performing the same task at hand is truly where the art comes in. In this post, I’d like to highlight some of the various pitfalls that lead to memory leaks, which inevitably result in crashes. I will also cover some tools and remedies to resolve these issues.
