/*
|
|
Typical reasons for an error here include:
|
|
* The parent directory does not exist, cannot be created, or disallows writing.
|
|
* The persistent store is not accessible, due to permissions or data protection when the device is locked.
|
|
* The device is out of space.
|
|
* The store could not be migrated to the current model version.
|
|
Check the error message to determine what the actual problem was.
