Simple and easy way to use Core Data. Inspired by Active Record.

• CRUD actions
• Search object by key and value

• iOS 9.0+
• Xcode 8.0+

An example can be found in the project. Just download and run the .xcproject to see it in action.

github "jaisonv/ActiveCoreData"

Copy the class ActiveCoreData.swift to your project.

Create a new Data Model file having the same name as the project.

Eg.: Project.xcdatamodeld

After creating the Core Data entities, select Editor > Create NSManagedObject Subclass.... This will generate the classes automatically.

Now it's just necessary to import ActiveCoreData where you need to manipulate the entities (if it wasn't added manually).

In the example we have an entity called Animal. If we want to create a new Animal just call create() as follows:

// create animal
let animal = Animal.create()

// set attributes
animal.species = "Dog"
animal.breed = "Chihuahua"
animal.name = "Rex"
animal.color = "Black"

To persist entity, simply call save(). After creating an entity it will only be persisted after this method is called.

// persist animal
animal.save()

findAll() will return an Array containing all the stored objects for that entity.

let animals = Animal.findAll() as! [Animal]
for animal in animals {
    print("Name: \(animal.name)")
    print("Breed: \(animal.breed)")
}

The method findAll(attribute: String, value: String) can be used to find an array of objects matching a specific attribute value. The attribute parameter is the property to search and the value parameter is its value.

let animals = Animal.findAll(attribute: "name", value: "Rex") as! [Animal]
for animal in animals {
    print("Name: \(animal.name)")
    print("Breed: \(animal.breed)")
}

findFirst() finds the first persisted object of type 'Animal'.

if let animal = Animal.findFirst() {
    print("Name: \(animal.name)")
    print("Breed: \(animal.breed)")
}

The method findFirst(attribute: String, value: String) can be used to find the first object matching a specific attribute value. The attribute parameter is the property to search and the value parameter is its value.

if let animal = Animal.findFirstByAttribute("name", value: "Rex") {
    print("Name: \(animal.name)")
    print("Breed: \(animal.breed)")
}

delete() will delete the persisted data.

animal.delete()

There are some stuff that would be nice to add and I will when I have more time. If you want to add something else or you have a feature request, just let me know.

Features to add:

• Asynchronous saving
• Support Cocoapods

If you have any questions feel free to ping me on Twitter.
