AlecrimCoreData Documentation

Welcome to the AlecrimCoreData documentation, which provides detailed information on how to use the AlecrimCoreData framework for efficient Core Data management in your iOS and macOS applications. AlecrimCoreData simplifies the implementation of Core Data stack and operations, allowing you to focus on your app’s business logic.

Getting Started

Before you start using AlecrimCoreData, you need to install it in your Xcode project. You can install it either manually or through CocoaPods.

To install AlecrimCoreData manually, download the latest release from the GitHub repository and add the necessary files to your project.

If you prefer to use CocoaPods, simply add the following line to your Podfile:


pod 'AlecrimCoreData'

Once you have AlecrimCoreData installed in your project, you can initialize it by following these steps:

  1. Create an instance of AlecrimCoreDataStack, which represents the Core Data stack.
  2. Configure the AlecrimCoreDataStack instance according to your app’s requirements, such as setting the persistent store type and options.
  3. Invoke the createManagedObjectContexts() method on the AlecrimCoreDataStack instance to create the managed object contexts.

Core Data Stack

The Core Data stack provided by AlecrimCoreData consists of a set of managed object contexts connected in a parent-child relationship, simplifying the handling of concurrent operations and data synchronization.

The Core Data stack includes the following managed object contexts:

  • Root Managed Object Context: The highest-level context, responsible for interacting with the persistent store coordinator and saving changes to disk.
  • Main Managed Object Context: The middle-level context used for most read and write operations.
  • Background Managed Object Context: The lowest-level context used for time-consuming or concurrent operations.

Working with Entities

To create a new entity using AlecrimCoreData, follow these steps:

  1. Create a new instance of the desired entity using the EntityDescription(name:) initializer.
  2. Set the properties of the newly created entity.
  3. Save the changes to the Core Data stack using the appropriate managed object context.

To fetch existing entities from the Core Data store, you can use AlecrimCoreData’s fluent querying API. Here’s an example:



let entities = self.dataContext
.tableFor(entity: MyEntity.self)
.filter(predicate: somePredicate)
.sort { $0.name < $1.name } .toArray()

Advanced Topics

AlecrimCoreData supports batch updates, allowing you to efficiently perform simultaneous changes to multiple entities. To perform batch updates, use the update(attribute:withValue:) method on a Table<T> instance.

AlecrimCoreData simplifies working with Core Data relationships by providing convenient methods for setting, modifying, and querying related entities.

AlecrimCoreData provides error handling mechanisms to gracefully handle Core Data related errors. You can utilize the provided AlecrimCoreDataErrorHandler struct to handle and manage errors.

If you require localized strings within your Core Data entities, AlecrimCoreData offers localization support through the AlecrimCoreDataLocalization struct. This allows you to store translations of entity properties in multiple languages.

AlecrimCoreData supports unit testing by providing a separate Core Data stack designed specifically for testing purposes. This enables you to easily run tests without affecting your production data.
