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.
Percentage-based Spacing Using Autolayout and Storyboard
Due to the many screen sizes in the mobile world, staying relative to screen size is crucial. Hard-coding margins and sizes based on points can be short-sighted. In this post, we will subclass NSLayoutConstraint to achieve percentage-based margins.
What’s New in iOS 10 and Beyond
It is clear from this year’s WWDC that Apple envisions a new era beyond the traditional apps-in-a-grid-on-your-home-screen model. iOS 10 is more of a revolutionary iteration to the Apple ecosystem and vision. There were many initiatives uncovered that gives us clues to the future of Apple.
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.
Protocol-Oriented TableView and CollectionView in Swift
Working with the UITableView and UICollectionView is verbose and inconvenient; also the API’s are inconsistent with each other. In this post, I’d like to reconcile the two API’s and add some sugar to make it more pleasant to work with these commonly used controls.
Protocol Conformance Extensions in Swift
Swift is a unique language that has some revolutionary ideas. One of which is protocol conformance extension. This concept allows you to take an existing type and force it to adopt another protocol it never knew it existed before.
