iOS has built-in support for adding shadows to UIView components. All you need to do in order to add a shadow to a UIView object is to set the shadow properties of the view’s layer. Shadows are a powerful user interface design element, making the visual components stand out by giving them a 3D look and feel. In order to display a shadow in Swift, iOS allows you to specify its color, opacity, offset and radius. Our recommendation is to try out different values for these variables, to see for yourself what are they exactly.

Localization is the process of adapting a client app to a specific language. A localized mobile app renders all its content in the user’s language. In this article, we discuss a few key aspects on why you should localize iOS apps. While it could be obvious while this is a good idea, most developers would rather not invest time for localizing their apps, when working on a minimum viable product. Even if you don’t plan on adding localization support initially, it’s recommended to keep an eye on localization while writing your code, to make sure you won’t run into much trouble when the time for localizing the app comes.

Writing highly-modularized code is critical in building a robust iOS app, that is scalable and extensible. To make a well-architected iOS app in Swift, there are various design patterns that can be used, to build a high-quality codebase. We focus a lot on building robust architecture in our Xcode app templates, so in this article we are sharing the way we leverage protocol-oriented programming in Swift, to create scalable iOS apps. We are not creating just one app, but instead, we are making a ton of app templates, so a good design is critical to our mission.

Debugging code written in Swift/Objective-C can be tricky sometimes, especially for someone who’s just starting to learn iOS programming. We’re listing a few techniques and tools for debugging code in Xcode, that any successful mobile app developer should be familiar with. The inspiration for this list was the work we’ve done building our beautiful iOS app templates.

Beautiful design drives more users to an app. It’s not only about the design of the app itself but also about the aesthetics of the overall App Store presentation of your app. This article contains several useful tips that will help you increase App Store downloads, by making enhancements to your screenshots.

As a mobile developer, design is among the top priorities of your daily job. The user interface is one of the most important aspects of a mobile app, so we thought a list of the best design resources out there would be useful for all iOS developers.

There are many situations when you'd like to add a header and footer to a UICollectionView component, in Swift. Regardless whether it's a simple title or a more advanced view, UICollectionView supports headers and footers out of the box, without too much boilerplate code.

WWDC 2020 has ended. As usually, Apple introduced a lot of new things during the conference. They include the transition from Intel chips to ARMs, new iMacs, new OSs. One of the most expected announcements also happened: SwiftUI 2.0. Let's discover if there is anything new in this version of SwiftUI, which starts to mature nicely.

It has been almost a year since SwiftUI was introduced at WWDC. We've tried SwiftUI for a few months now, and even built a premium fitness app just with SwiftUI. Unfortunately, after this adventure, we've decided, as a team, to not pursue SwiftUI apps any further. The framework is simply not ready for complex apps, and, to be honest, this should be embarrassing for Apple, given how low the quality bar was for this launch.

Although it's undeniable that SwiftUI has made breakthroughs in redefining how to build an iOS app, it still has difficulties building a real application which can get quite complex. Also, while SwiftUI is still a kid – we have to accept some issues as well as use hacky solutions and hope it gets better in the next releases.
