Core Data Lab lets you easily view, edit, and analyse data of SQLite-based Core Data and SwiftData apps. View, track, and explore what’s inside your Core Data database, including all Core Data-specific details like relationships, entity descriptions, fetch request templates, composite attributes, and more. Quick start • Set up a new project in a few easy steps using the project assistant. • Select an app or model file and let Core Data Lab search for a matching database. • Or select a database file and let Core Data Lab search for matching apps. • Or use the simulator browser to select a database and app combination in one go. Data change tracker • Hit the Play button on the toolbar to start tracking database changes. • New, deleted, and changed data rows are displayed with distinct colors. • Each previous row version is displayed individually, including all value changes. • No need to change your project or implement special libraries. • Works with macOS apps and apps running in an iOS, iPadOS, watchOS, tvOS or visionOS simulator. Data filter • Use the built-in easy-to-use predicate editor to filter and query your data. • Save predicates as part of a Core Data Lab project for easy access. • Duplicate predicates to make quick variants of the same filter. Data editor • Edit and create data directly in the inspector panel or detail window. • Delete rows directly in the data grid. • Change, replace, or nullify data with batch updates. • All data mutations are validated by the active Core Data Object model. Relationships viewer • View instantly all relationships and related data of a selected row. • Easily switch to another relationship. • Selecting a row in the relationship panel will show the data in the inspector panel. Simulator browser • Browse local iOS, iPadOS, watchOS, tvOS or visionOS simulators for Core Data apps and databases. • Add app and database combinations with one click to your project. Object model diagrams • Visualize your Core Data model in one or more diagrams, showing all entities, attributes, fetched properties, and relationships. • Inspired by the ‘graph style’ editor of the data model designer tool in Xcode 13 and older. • Exportable to PDF and clipboard. Content viewer • Automatic detection and display of web links, image data, HTML content, PLIST objects, binary content, and more. • Switch to Text view to inspect the HTML, XML, or JSON text content of web links. • Built-in HTML debugger. Entity description viewer • View all details of all attributes of a selected Core Data entity. • Inspect all other details like relationships, indexes, and constraints. Raw data viewer • Open and view SQLite databases without a Core Data object model. • Support for opening SQLite files in the Finder. Data import • Import data using CSV or JSON files. • JSON import supports relationship data and composite attributes. • All data import happens under validation of the active Core Data Object model. Data export • Export a selected row or table to CSV or JSON. • Export data tracking data to CSV or JSON including history data. • JSON export supports relationship data and composite attributes. • CSV data can be viewed and further processed in Excel or Numbers. Project-based • Your database, app, and model references are stored in a Core Data Lab project. • Data filters, selections, sorting settings, and diagrams are also part of the same project. • This makes it easy to stop and continue working with your data, without recreating anything. • Projects are saved as standard NSDocument files, including tabbed windows, auto-save, and more.
