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.
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.
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.
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.
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.
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.
In this post, I’d like to show you how to create a Swift framework for iOS, watchOS, and tvOS and get them distributed via Carthage and CocoaPods. It’s a technique I use to share frameworks across all my apps and with the community.
It is convenient to keep your settings or default values in a `.plist` file or settings bundle for your project. In this post, we will explore how to attach an extension off the NSBundle class this make it super easy to read those values.
Swift has a unique and elegant class inheritance system. In this post, I’d like to shed light on all the inheritance goodies in Swift, such as designated, convenience, failable, automatic, and required initializers. Not only are these powerful concepts, but they also enforce safe and intentful code.
