I'm trying to migrate a existing core data db into an app group so that it can be accessed by an apple watch.
So far i have tried
func migrateStore() {
persistentContainer = NSPersistentContainer(name: "Diamond_Painting_Logbook")
persistentContainer.loadPersistentStores { (description, error) in
if let error = error {
fatalError("Could not create CoreData store: \(error)")
}
var nURL = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: "group.Desbrina.dpl.Diamond-Painting-Logbook.shared")
nURL = nURL?.appendingPathComponent("Diamond_Painting_Logbook.sqlite")
if let newURL = nURL {
do {
let psc = self.persistentContainer.persistentStoreCoordinator
let store = psc.persistentStores[0]
NSLog("7 *****************")
try psc.migratePersistentStore(store, to: newURL, options: nil, withType: NSSQLiteStoreType)
NSLog("8 *****************")
} catch {
}
}
}
}Its throwing an error on the line.
try psc.migratePersistentStore(store, to: newURL, options: nil, withType: NSSQLiteStoreType)I'm asuming its because the destination file doesn't exist.
