Sync
A sync layer for SwiftData apps that handles JSON-to-model mapping, deterministic diffing, and reactive local reads.
What is Sync?
SwiftSync is a synchronization layer for SwiftData applications that automates the process of converting JSON data from a backend API into SwiftData models and vice versa. It solves the problem of manually writing repetitive sync logic by providing deterministic diffing, automatic relationship handling, and reactive local reads, allowing developers to focus on building their app's features rather than data synchronization boilerplate.
iOS and macOS developers building SwiftData-based applications that need to sync data with a backend API, particularly those using SwiftUI or UIKit who want reactive, automatic UI updates when data changes.
Developers choose SwiftSync because it eliminates the need to write custom sync code for every model, provides a convention-first approach that reduces configuration, and integrates seamlessly with SwiftData and SwiftUI for a reactive, local-first data flow.
