Summary
If you're one of the Realm users staring down that September 30, 2025 sunset deadline, this is your migration playbook. It covers the complete path from Realm to SwiftData with iOS 17+ support, though the author recommends iOS 26+ and Swift 6 for strict concurrency. The 948 GitHub stars and 168 installs suggest people are actually using this in production, which matters when you're making a database migration. Budget 2-8 weeks for a real app migration according to the guide itself. It's reference documentation, so expect completeness over hand-holding, but that's probably what you need when you're moving your entire data layer anyway.
