How to implement Encrypted Core Data in Existing project with Swift 5.3.2 #336

I have a project built with Xcode 12.2, Swift 5.3.2, and Core Data. Now I need to secure my core data with this library. I have already done lightweight migration for the project. How do I configure an existing project with this library? Please help me out.
Implementation as follows,
I’m always getting crash on container.loadPersistentStores with EXEC_BAD_ACCESS
lazy var persistentContainer: NSPersistentContainer = {
/*
The persistent container for the application. This implementation
creates and returns a container, having loaded the store for the
application to it. This property is optional since there are legitimate
error conditions that could cause the creation of the store to fail.
*/
let url = self.applicationDocumentsDirectory.appendingPathComponent(“MyTask.sqlite")
let container = NSPersistentContainer(name: “MyTask”)
do {
let options = [
EncryptedStorePassphraseKey : “xxxxxxxxxxx”,
EncryptedStore.optionFileManager()! : EncryptedStoreFileManager.default()!
] as [String : Any]
let description = try EncryptedStore.makeDescription(options: options, configuration: nil)

        // Create Persistent Store Description
        let persistentStoreDescription = NSPersistentStoreDescription(url: url)
        // Configure Persistent Store Description
        persistentStoreDescription.type = EncryptedStoreType
        //persistentStoreDescription.setOption(NSString("xxxxxxxxxxx"), forKey: NSPersistentStoreFileProtectionKey)
        persistentStoreDescription.shouldMigrateStoreAutomatically = true
        persistentStoreDescription.shouldInferMappingModelAutomatically = true
        container.persistentStoreDescriptions = [persistentStoreDescription]
    }
    catch {
        NSLog("Could not initialize encrypted database storage: " + error.localizedDescription)
    }
    container.loadPersistentStores(completionHandler: { (storeDescription, error) in
        if let error = error as NSError? {
            // Replace this implementation with code to handle the error appropriately.
            // fatalError() 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.

            /*
             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.
             */
            fatalError("Unresolved error \(error), \(error.userInfo)")
        }
    })
    return container
}()
