Powerful & superfast database for Swift that's also easy to use. Persist Swift objects quickly and reliably on-device on iOS and macOS.
// objectbox: entity
class Person {
var id: Id = 0
var firstName: String = ""
var lastName: String = ""
init() {}
init(id: Id = 0, firstName: String, lastName: String) {
self.id = id
self.firstName = firstName
self.lastName = lastName
}
}
let store = try Store(directoryPath: "person-db")
let box = store.box(for: Person.self)
var person = Person(firstName: "Joe", lastName: "Green")
let id = try box.put(person) // Create
person = try box.get(id)! // Read
person.lastName = "Black"
try box.put(person) // Update
try box.remove(person.id) // Delete
let query = try box.query { // Query
Person.firstName == "Joe"
&& Person.lastName.startsWith("B")
}.build()
let people: [Person] = try query.find()Want details? Read the guides or check out the API docs.
Simple but powerful; frugal but fast: The ObjectBox NoSQL database offers an intuitive Swift API that's easy to pick up, fun to work with, and incredibly fast, making it sustainable in many ways. Its frugal recource use (CPU, memory, battery / power) makes ObjectBox an ideal and sustainable choice for iOS apps. So why not give it a try right away? Check out the installation section below.

This might be relevant, e.g. when using Carthage. For various reasons, we recommend using the latest version.
For notable and important changes in new releases, read the changelog.
The source code for ObjectBox's Swift binding can be found in the Source folder of this repository.
ObjectBox Swift Database uses generated code for optimal performance at runtime by avoiding reflection etc.
It uses a fork of Sourcery for this.
