With the official release of Swift 6.1, SwiftWasm has also undergone a major upgrade. This milestone update marks the first time SwiftWasm has achieved a build entirely based on the official Swift open-source toolchain—leaving behind the era of custom patches. This change not only significantly simplifies the installation process for developers and greatly reduces the consumption of system storage, but more importantly, the genuine build method drastically lowers platform maintenance costs and injects new vitality into the Swift ecosystem. In this article, we will explore how to build WebAssembly applications using Swift, showcasing the endless possibilities of Swift's cross-platform development.

Overusing SwiftUI’s dismiss can harm app stability and maintainability. Instead, manage view dismissal through Binding, functions, or custom environment values to ensure clear, testable, and predictable UI behavior. This state-driven approach helps avoid hidden performance issues and builds a more robust architecture.

SwiftUI’s Environment is a powerful and elegant mechanism for dependency injection, and almost every SwiftUI developer encounters and uses it in daily development. Not only does it simplify data transfer between views, it also opens up greater possibilities for application architecture design. In this article, we will set aside specific implementation details and instead focus on the role and boundaries of Environment within an architecture, exploring some often-overlooked yet crucial design ideas and practical experiences.

In the Internet age, developers increasingly interact with network data. Just as we rely on the debugging features of our IDEs to optimize our code, network debugging tools have become indispensable assistants for quickly, efficiently learning, researching, and analyzing network data. This article explains how to use Proxyman to capture the network request information of an iPhone app and simulate server responses by providing mock data. This allows you to test and develop applications without relying on a real server.

This article aims to serve as a guide for developers interested in SwiftData, helping you understand its strengths and limitations so you can make informed decisions based on your project needs. Whether you’re considering adopting SwiftData in a new project or planning a migration from another persistence solution, the following content will provide valuable insights to support your decision-making process.

The Observation framework has brought native property-level observation to Swift, effectively preventing unnecessary view updates in SwiftUI triggered by unrelated property changes, thereby enhancing application performance. However, since @State does not offer a lazy initialization constructor like @StateObject, it may lead to performance degradation or even logical issues due to the premature construction of instances in certain scenarios. This article explores how to implement a lazy initialization solution for Observable instances using @State.

In SwiftUI development, have you ever encountered situations where seemingly correct animation code fails to work as expected? Or animations that run perfectly on certain iOS versions but behave abnormally on others? These frustrating animation issues can often be resolved with a powerful yet understated tool — the Animatable protocol.

In the past month and a half, I’ve made a series of adjustments to my blog, covering areas such as the publishing mechanism, code architecture, and layout design. These changes have not only enhanced the performance and user experience of the blog but also made content maintenance and updates more efficient. This article provides a brief overview of the key changes.
