I’m facing this issue on the screenshot every second time or so. Happens on chapter 7’s starter project with a few added tests.
Here’re some tips that this relates to wrong module name being used in testing environment: ios - Swift Unit Test EXC_BAD_ACCESS(code=1, address=0x8) - Stack Overflow
I’ve converted SO answer swift 3 , fed it to NSPersistentContainer’s init and it didn’t help:
lazy var managedObjectModel: NSManagedObjectModel =
{
let modelURL = Bundle.main.url(forResource: self.modelName, withExtension: "momd")
let managedObjectModel = NSManagedObjectModel(contentsOf: modelURL!)
let environment = ProcessInfo.processInfo.environment
let isTest:Bool
if let count = environment["XCTestConfigurationFilePath"]?.characters.count, count > 0 { isTest = true }
else { isTest = false }
let moduleName = (isTest) ? "CampgroundManagerTests" : "CampgroundManager"
// Create a new managed object model with updated entity class names
var newEntities = [] as [NSEntityDescription]
for entity in managedObjectModel!.entities
{
let newEntity = entity.copy() as! NSEntityDescription
newEntity.managedObjectClassName = "\(moduleName).\(entity.name)"
newEntities.append(newEntity)
}
let newManagedObjectModel = NSManagedObjectModel()
newManagedObjectModel.entities = newEntities
return newManagedObjectModel
}()
I also see this in the top of my console output:
CoreData: warning: Unable to load class named ‘CampgroundManagerTests.Optional(“CampSite”)’ for entity ‘CampSite’. Class not found, using default NSManagedObject instead.
What’s the simplest way to fix this error?
Thanks
