Consider implementing a SwiftData Custom Store (new in iOS18) for Realm about realm-swift HOT 6 OPEN

I don't think Realm is a good candidate for this. The example that Apple gave for this custom storage engine was a JSON file. "Translating" Realm's storage engine to SwiftData on-the-fly seems like it would destroy many features: live objects, lazy-loading of the data behind objects, etc. And the extra layer of abstraction seems like it would murder performance and make debugging even more of a nightmare.

The sad reality is that Apple screwed up. They should have bought Realm before Mongo did and they should have integrated it as a first-party replacement for Core Data. They should have recognized that, in the modern world, developers want a data persistence framework that is available EVERYWHERE--not just on Apple platforms.

Tying yourself to SwiftData is a mistake. You're hamstrung to Apple's platforms, you'll get updates and bug fixes exactly once per year, at WWDC, and most of those will be unusable for a long time because you'll have to target a new version of iOS/macOS/watchOS, but your users won't be on that version of the platform for years.

By contrast, Realm updates every few weeks, you can adopt those updates immediately, and you're never tied to a single platform--use Realm anywhere you want; there are SDKs for everything.

Kick Apple's data persistence nonsense to the curb.

My RealmSwift-using code has zero portability so I'm not sure what you mean about multi platform availability being key?

@aehlke Let's say you have a simple "todo" app. You want to create an iOS version, an Android version, and a web app version. If you use Swift Data and CloudKit for your app, good luck building on the latter two platforms. By contrast, Realm has an SDK for each and it talks to the same source of truth in the cloud.

Oh I see - I don't use Realm's cloud services (I have Realm automatically background syncing with CloudKit + my own servers)

I'm hoping https://skip.tools prioritizes the ticket for porting RealmSwift usage to Android
