Developed by Stability AI in collaboration with academic researchers and non-profit organizations, Stable Diffusion is a deep learning model that generates detailed images based on text descriptions or what so called text prompts. Additionally, it can also be utilized for tasks such as inpainting, outpainting, and generating image-to-image translations guided by text prompts. Since its public debut in August 2022, it has gained popularity among artists, developers, and hobbyists. Stable Diffusion is not the only text-to-image model. You may have heard of Midjourney or DALL-E 2, which are also ..read more

In an earlier tutorial, we shared how to create a custom tab bar view using SwiftUI to replace the standard tab bar. If you’ve already read that tutorial, you know that building your own tab bar is not a difficult task. That said, we have taken it one step further by developing a collection of animated tab bars for your convenience. With our pre-built tab bars, you can choose the one that best suits your project and integrate it seamlessly into your SwiftUI app. Let me introduce our new MotionBar library. This brand new library offers a collection of beautifully ..read more

Whether you’re creating a social media app or a productivity tool, the tab bar interface can enhance the user experience by making it more intuitive and user-friendly. With SwiftUI’s TabView, creating a seamless and customizable tab interface has never been easier. By default, iOS displays the tab bar in its standard form, allowing users to quickly switch between different app functions with ease. However, as a developer, you probably want to customize the tab bar to fit the specific needs of your app. In this tutorial, you’ll learn how to create a scrollable and animated tab bar which support ..read more

The SwiftUI framework comes with a built-in checkbox, but it’s only available on the macOS platform. If you want to use checkboxes on iOS, you have to build your own component. Previously, we’ve covered ToggleStyle to create custom toggles. By applying the same technique, it’s not hard to build a checkbox for your iOS projects. Using Checkbox on macOS Let’s first take a look how you use checkbox on macOS. To create a checkbox, you create a Toggle view and change it to the .checkbox style. Here is an example: If you run the code on macOS, it renders a ..read more

Toggle in SwiftUI is one of the most used views that it allows users to switch between two states, either on or off. This control is a great way to provide a simple and intuitive interface for your users, making it a popular choice for many developers.For example, you might use a toggle in your app to turn on and off certain features, or to switch between different modes or options. Toggle is very easy to implement in your SwiftUI applications. With the ToggleStyle protocol, you can create toggles that match your app’s design and branding. In this tutorial, I ..read more

So, what’s QR code? I believe most of you know what a QR code is. In case you haven’t heard of it, just take a look at the above image – that’s a QR code. QR (short for Quick Response) code is a kind of two-dimensional bar code developed by Denso. Originally designed for tracking parts in manufacturing, QR code has gained popularity in consumer space in recent years as a way to encode the URL of a landing page or marketing information. Unlike the basic barcode that you’re familiar with, a QR code contains information in both the horizontal ..read more

In iOS development, navigation view is definitely one of the most commonly used components. When SwiftUI was first released, it came with a view called NavigationView for developers to build navigation-based user interfaces. With the release of iOS 16, Apple has deprecated the old navigation view and introduced a new view known as NavigationStack to present a stack of views. Most importantly, developers can make use of this new view to build data driven navigation. The Old Way of Navigation Views Prior to iOS 16, you create a navigation interface using NavigationView and NavigationLink like th ..read more

As you know, Apple released Xcode 14 and iOS 16, along with the debut of iPhone 14. Now our Mastering SwiftUI book is updated to support the latest version of iOS and Xcode. All the content including screenshots and source code are updated for Xcode 14 and iOS 16. On top of that, we added over 100 pages of new content to teach you the new APIs of SwiftUI. After three years of development, the SwiftUI framework becomes more and more mature. And it’s ready for production development. If you think it’s time to learn this new framework, our Mastering SwiftUI book ..read more

In iOS 16, SwiftUI introduces a new view called Gauge for displaying progress. You can actually use it to show values within a range. In this tutorial, let’s see how to use the Gauge view and work with different gauge styles. A gauge is a view that shows a current level of a value in relation to a specified finite capacity, very much like a fuel gauge in an automobile. Gauge displays are configurable; they can show any combination of the gauge’s current value, the range the gauge can display, and a label describing the purpose of the gauge itself ..read more
