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.
Swifty Locations with Observables
Let’s use the closure-based pattern to wrap CLLocationManager for allowing callers to subscribe to observables instead of using shared delegate functions.
Delegates to Swift Closure Pattern
Delegation is a simple and powerful pattern. However, closures are more Swifty and scales better. Let’s convert delegates to closures!
Creating Thread-Safe Arrays in Swift
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.
Multi-Threading with Unsafe Resources in Swift
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.
Full Stack iOS and WordPress in Swift
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 […]
Enum-based Queue Factory for GCD
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.
Common Initializer Patterns in Swift
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.
Memory Leaks and Resource Management in Swift and iOS
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.
Swift Utility Belt Series: Introduction
Swift is a powerful and fun language. Its protocol-oriented nature allows you to do retroactive modeling and promotes composition over inheritance. In this series of posts, I will share Swift snippets that I’ve used across projects that I feel are really helpful in rapid development.
