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.

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.

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.

While working on the SwiftUI Chat tutorial, we ran into the issue of handling the keyboard animations by adjusting the layout of all the views visible on the screen, depending on whether the keyboard is visible or not. In this tutorial, we are going to learn how to handle the keyboard animations in SwiftUI with the help of ObservedObject.

In this detailed tutorial, we are taking a look at how you can add and customize an iOS launch screen in your iOS app and why it's important to take your launch screen design seriously. The task itself is not difficult, and I'll assume you are writing your iOS app in Swift, using Xcode.

Note: If you come from an Android/React Native background, you might have used "splash screen" to describe this app starting screen. Apple prefers "Launch Screen", which is what we're going to use in this article.

Hey everyone, in this article, we are going to learn how to build custom reusable components with ViewModifier, and how to create base views with ViewBuilder. These are powerful mechanisms to implement gorgeous design systems that are consistent across the entire app and that encourage code reusability and good architectural patterns.

In this iOS tutorial, we are going to learn how to implement a tab bar in SwiftUI by leveraging TabView. Feel free to skip directly to the source code (at the bottom of the page), if you already know what you're doing.

Hello, welcome back to our SwiftUI tutorials series. In this article, we are going to learn how to use the photo camera and library picker in SwiftUI to take photos within our iOS apps – a feature that nearly every mobile application needs nowadays, especially with the latest iPhone release, that has 3 cameras!
