Apple recently notified developers submitting apps for review to include privacy manifest files in their apps if they use specific APIs. This requirement stems from the new policy introduced at WWDC 2023, aimed at compelling app developers and SDK producers to explicitly declare their app's privacy practices. By May 1, 2024, apps that fail to provide a complete privacy manifest will not pass the App Store's review process. Developers are required to provide clear privacy statements for the APIs or third-party libraries used, ensuring transparency and the protection of user privacy. 订阅中文版 RSS ..read more

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. 订阅中文版 RSS Read More ..read more

In the previous article "Concurrent Programming in SwiftData", we delved into the innovative concurrent programming model proposed by SwiftData, including its principles, core operations, and related considerations. This elegant programming solution has earned considerable praise. However, as more developers attempt to use SwiftData in actual SwiftUI applications, they have encountered some challenges, especially after enabling Swift's strict concurrency checks. They found that SwiftData's actor-based concurrency model is difficult to integrate with traditional application construction methods ..read more

In the SwiftUI framework, lazy layout containers such as List and LazyVStack provide a method for efficiently displaying large datasets. These containers are ingeniously designed to dynamically build and load views only when necessary, thereby significantly optimizing the app's performance and memory efficiency. This article will explore some practical tips and important considerations aimed at enhancing developers' ability to leverage SwiftUI's lazy containers for improved app responsiveness and resource management. 订阅中文版 RSS Read More ..read more
