In SwiftUI, many layout container constructors include a spacing parameter with a default value of nil, which controls the spacing between adjacent views. This article will start with this default parameter to explore the concept of Spacing in SwiftUI in-depth, and share some related tips and considerations.

At the WWDC 2023, Apple introduced the containerRelativeFrame view modifier to SwiftUI. This modifier simplifies some layout operations that were previously difficult to achieve through conventional methods. This article will delve into the containerRelativeFrame modifier, covering its definition, layout rules, use cases, and relevant considerations. At the end of the article, we will also create a backward-compatible replica of containerRelativeFrame for older versions of SwiftUI, further enhancing our understanding of its functionalities.

In this article, I will share some of my experiences and attempts at using the Swift language for embedded development on the SwiftIO development board.

In the toolbox of SwiftUI, overlay and background are two extremely useful view modifiers that play an indispensable role in various development scenarios. This article will delve into the unique attributes of these two modifiers, clarify their fundamental differences from ZStack, and identify the scenarios they are best suited for.

Apple recently updated its App Store Review Guidelines, now allowing emulator apps into the App Store. Just a few days ago, an emulator app named Delta was launched on the store. Delta is an all-in-one emulator designed for iOS, supporting a variety of Nintendo handheld games. This app was actually developed a long time ago but was previously only available to users in non-App Store formats due to policy restrictions.

SwiftData, as the successor to Core Data, has introduced a multitude of innovative and modern design ideas. Despite its availability for some time now, many developers have yet to adopt it in their projects. This situation is partly due to SwiftData’s higher requirements for the operating system version. Additionally, because SwiftData is not yet mature enough in some functionalities, developers might choose to continue using Core Data even if their operating system version meets SwiftData’s requirements. Can we integrate some of SwiftData’s excellent design philosophies and ingenious implementations into the practical use of Core Data? This article aims to explore how to introduce elegant and safe concurrency operations similar to those of SwiftData into Core Data, implementing a Core Data version of @ModelActor.

Although these new frameworks were designed to address issues in existing frameworks, we should not be constrained by past experiences and conventions. It is necessary to learn and use these new tools with an open mind and a fresh perspective. Adopting new frameworks should be seen as an excellent opportunity to refactor projects towards greater safety and modernization.

An increasing number of developers are starting to enable strict concurrency checks in preparation for the arrival of Swift 6. Among the warnings and errors received, a portion relates to SwiftUI views, many of which stem from developers not correctly understanding or using @MainActor. This article will discuss the meaning of @MainActor, as well as tips and considerations for applying @MainActor within SwiftUI views.
