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.
