Encountering "Missing Mapping Model" Error When Running iPad-designed Core Data App on Mac.

Forums > macOS

Encountering a fatal 'Persistent store migration failed, missing mapping model' issue when running a Core Data app on Mac (originally designed for iPad). Despite attempting common Xcode troubleshooting, the problem persists. It's the first time running on the Mac simulator, and there are no migration issues on iPhone/iPad sim or physical devices. Unsure if any specific steps are needed for Mac compatibility. Any insights appreciated.


The 'Persistent store migration failed, missing mapping model' issue on a Mac simulator may be due to differences in the underlying architecture. Ensure that the data model is compatible with Mac, double-check the mapping model, and confirm that all entities and relationships are accurately represented. Additionally, review any platform-specific code or configurations that might be affecting Core Data migration on macOS.
