Presenting data through graphs and charts is one of the most remarkable features of mobile applications today. iOS Charts make apps look more beautiful and noticeably more attractive. We already integrated a number of Swift Charts into many mobile app templates such as the Dashboard iOS App Template or Personal Finance iOS App Template.

In today’s privacy-focused world, keeping a high bar for the security of our iOS apps, by storing critical user data securely is more important than ever. When handling sensitive user data such as passwords, in-app purchases, etc, in iOS apps, a mobile developer needs to take security into consideration. In our App Templates, we are taking security very seriously, by making it part of our core values. In this tutorial, we will show you how to use the Keychain in Swift to store sensitive user data by implementing a persistent login feature on iOS.

As we have mentioned in previous posts, there are more and more iOS applications in App Store and obviously we are living in a highly competitive market. Hence, creativity and differentiation are essential for success. In today’s article, we will show you a great feature that makes apps feel more playful and performant – haptic feedback. We’ll learn how to generate haptics feedback in Swift with code examples.

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.

UIImage is the Swift approach to modeling images. In order to display an image on the screen, you’re most likely going to use UIImageView, which takes a UIImage object and presents it in the view hierarchy. To color UIImage objects there’s some extra work required. Coloring images can be very helpful when dealing with app icons, tab bar items, navigation items, etc.

Open Source Swift Libraries are becoming more diverse and are growing in numbers quickly, as Swift becomes more mature. In this article, we curated the best open source Swift Libraries that you can use to bootstrap your next iOS project. They will make your codebase more robust, more performant and will allow you to ship iOS projects more quickly.

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.

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.
