Why I'm Still Thinking About Core Data in 2026 Core Data remains widely used in 2026, but its mismatch with modern Swift concurrency, type safety, and code expression is growing. This article outlines the three core pain points and introduces a path to modernization without abandoning Core Data.

Core Data turns 21 this year — not dead, but showing its age. Concurrency hides behind `perform`, models drown in boilerplate, and string predicates still fail at runtime. This isn’t a call to leave; it’s asking: if you stay, what can you actually fix?

Huge shoutout to this week's sponsor: Notepad.exe by @krzyzanowskim.com

Try Swift 6 without Xcode bloat or slow Playgrounds. Notepad.exe runs code in ~30 seconds—no project setup. Multi-toolchain, simulator support: open and code.

Why Does Passing NSManagedObjectContext Across Isolation Domains No Longer Error in Swift 6.2? The Real Change Isn't in the Compiler Why NSManagedObjectContext no longer triggers concurrency errors in Swift 6.2? The real change lies in Core Data’s SDK import semantics, not the compiler itself. NSManagedObjectContext is now marked with NS_SWIFT_SENDABLE and NS_SWIFT_NONISOLATED in Xcode 26

In Swift 6.2 (Xcode 26.3), why can `NSManagedObjectContext` cross actor isolation?

I dug through the Core Data headers to find the real reason—here it is.
