Introducing XCDataModel
Xcode's Core Data editor works fine for a handful of entities. But on a real project — dozens of entities, inverse relationships you have to verify by hand, multiple .xcdatamodeld versions to compare — it stops being useful exactly when you need it most. XCDataModel is a standalone Mac app for the moments Xcode can't keep up: onboarding a teammate, planning a migration, or reviewing a PR that touches the data layer.
What it does
Drop any .xcdatamodeld file onto XCDataModel and your entire schema appears as an interactive canvas. Entities are laid out as nodes, relationships are drawn as arrows between them, and you can pan, zoom, and rearrange everything freely.
- Open
.xcdatamodeldfiles directly — no Xcode project required - Interactive canvas with zoom, pan, and undo/redo
- Auto layout to tidy up the diagram in one click
- Sidebar to search and jump to any entity
- Focus mode to isolate a single entity and the relationships it touches
- Double-tap any entity to inspect its attributes and fetch requests
See it in action
Open any .xcdatamodeld file
Drag a .xcdatamodeld file onto the app or pick one from recents. No Xcode project needed — XCDataModel opens it directly.
Explore the full schema
The entire model appears as an interactive canvas. Entities are laid out as nodes, relationships are drawn as arrows between them, and you can pan, zoom, and rearrange everything freely.
Inspect any entity
Select an entity in the sidebar to focus on it. Its attributes, relationships, and fetch requests appear in detail, while the rest of the diagram stays visible for context.
Platform
XCDataModel is a native Mac app, available on the Mac App Store.
