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.
