A Deep Dive into SwiftUI Rich Text Layout: Beyond AttributedString — Inside MarkdownView and RichText

As the creator of MarkdownView and RichText, LiYanan has not only resolved numerous pain points regarding SwiftUI Markdown rendering and mixed text layout, but his solutions have also been adopted by heavyweight products like X (Grok). In this post, I invited him to unreservedly share his technical evolution—from initial experiments based on the Layout Protocol and the pitfalls of TextRenderer, to ultimately achieving a flawless interactive experience through the underlying TextKit.

Using MainActor.assumeIsolated to Solve Legacy API Compatibility Issues with Swift 6

While Swift has offered strict concurrency checking for some time, many of Apple's official APIs have yet to be fully adapted, and this situation may persist for quite a while. As Swift 6 gradually gains adoption, this problem becomes increasingly prominent: developers want to benefit from the concurrency safety guarantees provided by the Swift compiler, while struggling with how to make their code meet compilation requirements. This article will demonstrate the clever use of MainActor.assumeIsolated in specific scenarios through an implementation case with NSTextAttachmentViewProvider.

Swift 6: Sendable, @unchecked Sendable, @Sendable, sending and nonsending

Swift's concurrency model introduces numerous keywords, some of which are similar in naming and purpose, often causing confusion among developers. This article examines several keywords related to cross-isolation domain passing in Swift concurrency: Sendable, @unchecked Sendable, @Sendable, sending, and nonsending, helping you understand their respective roles and use cases.

Default Actor Isolation: New Problems from Good Intentions

While Swift's strict concurrency checking has good intentions, it significantly increases the burden on developers in many single-threaded scenarios. Developers are forced to add unnecessary Sendable, @MainActor, and other declarations to their code just to satisfy the compiler's requirements. Swift 6.2's new Default Actor Isolation feature will greatly improve this situation and reduce unnecessary boilerplate code. This article will introduce the Default Actor Isolation feature and point out some situations to be aware of when using it.

Core Data Migration Incident Analysis: The Hidden Traps We Overlooked

Compared to some open-source frameworks, Core Data and SwiftData, despite having Apple's official endorsement, often leave developers helpless when exceptions occur due to their "black box" nature, making it difficult to quickly locate problems and find effective solutions. This article documents an app startup timeout incident caused by Core Data model migration, shares the solution, and deeply analyzes the underlying causes.
