This article aims to explore several common misconceptions of SwiftUI to help developers better understand and utilize SwiftUI. We will dissect these misconceptions, including those about the perceived difficulty of learning SwiftUI, expectations of cross-platform development, the scope of framework capabilities, and misunderstandings about the amount of code involved. By clarifying these concepts, we hope to provide clearer learning directions and usage strategies for SwiftUI developers.

The advent of SwiftUI has brought revolutionary changes to Apple ecosystem development, but it still faces some challenges when addressing certain complex requirements. Recently, I developed a component called Infinite4Pager, which supports infinite four-direction scrollable paging. In this article, we will analyze the key ideas in the implementation process, discuss the points that need special attention, and candidly review the shortcomings of SwiftUI in coping with such scenarios. Through this case, we not only learn the specific technical implementation but also better understand how to break through the convention and solve problems creatively within the framework of SwiftUI.

Announced at WWDC23, Swift introduces an amazing new way for internationalization (i18n) for Swift apps and packages with String Catalogs. This guide covers the basics of getting started with String Catalogs in a new project: WWDC23 String Catalogs. However, it doesn't touch on a use case where there is a single monorepo with multiple Swift packages (and there are no sample projects). In this article, we'll explore how to set up your monorepo so each Swift Package can have its own String Catalog, which gets auto-merged into one when building your host app, without breaking a sweat!

In the world of SwiftUI, List and LazyVStack, as two core lazy containers, offer robust support for developers to display large amounts of data. However, their similar performance in certain scenarios often causes confusion among developers when making a choice. This article aims to analyze the characteristics and advantages of these two components to help you make a better decision.

Since the inception of the Swift language, XCTest has been the preferred testing framework for the majority of Swift developers. However, deeply rooted in Objective-C, its API design heavily borrows from the traditions of that language, failing to fully reflect the modern best practices of Swift programming. In some respects, this has even become a barrier to further development. To overcome these limitations, Apple officially introduced Swift Testing at WWDC 2024—a new testing framework specifically designed for the Swift language. This framework has been integrated into Xcode 16 and positioned as the official testing tool of choice. In this article, we will delve into the features, usage, and unique aspects of the Swift Testing framework, analyzing how it helps developers write test codes faster (Swifter) and more in line with Swift programming habits (Swifty).

At WWDC 2024, Apple once again introduced a series of remarkable new APIs for SwiftUI's ScrollView component. These new features not only enhanced developers' ability to control scrolling behaviors but also reflected the ongoing evolution of the SwiftUI framework's design philosophy. This article will explore these latest scroll control APIs and review the development of all significant APIs related to scroll control since the inception of SwiftUI. Through this micro view, we will reveal the changes in SwiftUI's design style over the past few years and the underlying macro design trends.

The Text component is extremely common in SwiftUI applications. Over the past few years, despite Apple continually expanding its capabilities, developers have been eager for deeper control over this component. At WWDC 2024, SwiftUI introduced the TextRenderer protocol, granting developers new powers to adjust the rendering performance of the Text component, making it possible to achieve many previously unimaginable effects. This article will delve into this new feature.

WWDC 2024 has successfully concluded. Throughout this week, Apple showcased a series of new features and functionalities that will significantly impact the future. I will share my thoughts and feelings about several aspects that particularly resonated with me, reflecting on the highlights of this WWDC.
