Swift 6.1 unleashes official WebAssembly builds through SwiftWasm—no patches required. Dive into this article to discover how to craft WebAssembly apps with Swift and unlock the boundless potential of cross-platform development.
In SwiftUI, dismiss is popular for its flexibility, but overusing it can introduce hidden risks, testing challenges, and stability issues. Opt for state-driven methods like Binding or custom environments for safer, more maintainable UI logic.
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.
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.
