Seru (セル)

Core Data in Swift.

Seru (Cell in Japanese) is a clean and beautiful Core Data stack in Swift.
Seru is design to be light and fast and to fit all type of applications.

Use example: Setup Core Data in 1 line of code Seru() and insert object in background.

let seru = Seru()

seru.performBackgroundSave({ context in
  let person = Person(managedObjectContext: context)
  person.name = "Petter"
}

Usages

class AppDelegate: UIResponder, UIApplicationDelegate {            
  lazy var seruStack = Seru()
  ...
}

Actions

var seruStack: Seru
seruStack.persist()

}
