Core data migration - Appstore build crashing on iOS 8 devices, working on iOS 9

1
votes

My app store update build is crashing, it's a core data crash but I am getting this crash on only iOS 8 devices, it is working fine on iOS 9 devices. I have correctly performed light weight migration as well added the new model version keeping the old one as a base, added the dictionary in options as well while adding "addPersistentStoreWithType".

ManagedObjectModel

lazy var managedObjectModel: NSManagedObjectModel = {
    // The managed object model for the application. This property is not optional. It is a fatal error for the application not to be able to find and load its model.
    let modelURL = NSBundle.mainBundle().URLForResource("abcProject", withExtension: "momd")
    NSLog("Url is -  \(modelURL)")
    return NSManagedObjectModel(contentsOfURL: modelURL!)!
}()

PersistentStoreCoordinator

 lazy var persistentStoreCoordinator: NSPersistentStoreCoordinator? = {
    var coordinator: NSPersistentStoreCoordinator? = NSPersistentStoreCoordinator(managedObjectModel: self.managedObjectModel)
    let url = self.applicationDocumentsDirectory.URLByAppendingPathComponent("abcProject")
    var error: NSError? = nil
    var failureReason = "There was an error creating or loading the application's saved data."
    do {
        let mOptions = [NSMigratePersistentStoresAutomaticallyOption: true, NSInferMappingModelAutomaticallyOption: true]
        NSLog("TEST564 - 7 URL - \(url)")
        try coordinator!.addPersistentStoreWithType(NSSQLiteStoreType, configuration: nil, URL: url, options: mOptions)
    } catch var error1 as NSError {
        error = error1
        coordinator = nil
        // Report any error we got.
        var dict = [String: AnyObject]()
        dict[NSLocalizedDescriptionKey] = "Failed to initialize the application's saved data"
        dict[NSLocalizedFailureReasonErrorKey] = failureReason
        dict[NSUnderlyingErrorKey] = error
        error = NSError(domain: "YOUR_ERROR_DOMAIN", code: 9999, userInfo: dict)
        // Replace this with code to handle the error appropriately.
        // abort() causes the application to generate a crash log and terminate. You should not use this function in a shipping application, although it may be useful during development.
        NSLog("TEST564 Unresolved error \(error), \(error!.userInfo)")
        abort()
    } catch {
        fatalError()
        NSLog("TEST564 FATAL error")

    }

    return coordinator
}()

Above is my set of code for reference. I have searched everywhere and I get details about the light weight migration only.

Following is the device log after crash:-

Do you have any detail at all about the crash? Right now it's not even clear what indicates that the crash is due to migration. – Tom Harrington
I have edited the question with the complete device log crash after install. Please have a look into it and let me know if you are able to find the issue . Thanks – Manish Pathak
I am also facing same issue.Migration works on iOS 9 device but crashing on iOS 8 devices. – Desert Rose
@DesertRose - Can u please send the same two set of codes which I have put , for my reference ? – Manish Pathak

The error, Can't find model for source store says that when the app tried to migrate the persistent store, it could not find the data model that had been used to create the store. Data migration requires both the old and new data stores. The old one is used to load the data, and the new one is used to update the data for future use.

The reason this works on iOS 9 is that iOS 9 added model caching for use in lightweight migrations of SQLite stores. On iOS 9 you can therefore get a successful migration without the old model, because the old version will be automatically cached. This feature was not available on iOS 8, so if you're still supporting 8 then you still need to include the old version of the model in your app.

Finally I got it resolved by doing a simple change .

Earlier code :-

url = self.applicationDocumentsDirectory.URLByAppendingPathComponent("abcProject1")

Fixed code :-

url = self.applicationDocumentsDirectory.URLByAppendingPathComponent("abcProject1.sqlite")

adding <.sqlite> extension to my url path solved the issue for me. It is fully tested with all the possible scenarios. Thank you all for your help.

To avoid the crash I created new database for iOS 8 because I didnt need existing data that much.

I changed my storeURL from

let url = self.applicationDocumentsDirectory.URLByAppendingPathComponent("abcProject")

to

let url:NSURL
if (OS_VERSION<9.0)
{
    url = self.applicationDocumentsDirectory.URLByAppendingPathComponent("abcProject1")
}
else
{
    url = self.applicationDocumentsDirectory.URLByAppendingPathComponent("abcProject")
}

This fixed the crash for me.
