iOS: Delete ALL Core Data Swift

Question

I am a little confused as to how to delete all core data in swift. I have created a button with an IBAction linked. On the click of the button I have the follow

Answer 1

Swift 4 :

destroyPersistentStoreAtURL(_:withType:options:) will delete (or truncate) the target persistent store. This will safely destroy a persistent store.

Add:

do {
    try persistentStoreCoordinator.addPersistentStore(ofType: NSSQLiteStoreType, configurationName: nil, at: persistentStoreURL, options: nil)
} catch {
    // Error Handling
}

Destroy / Delete / Truncate:

do {
    try persistentStoreCoordinator.destroyPersistentStoreAtURL(persistentStoreURL, withType: NSSQLiteStoreType, options: nil)
} catch {
    // Error Handling
}

Note : Parameters in above method should be identical to addPersistentStoreWithType method. You need to re-initiate storeCoordinator to use store again.
