ObjectBox Swift Database - swiftly persist objects and on-device vector database for iOS & macOS

Powerful & superfast database for Swift that's also easy to use. Persist Swift objects quickly and reliably on-device on iOS and macOS.

Demo code

// 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()

Why use ObjectBox for Swift data persistence?

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. You can also star this repository for later 🌟

Features

🧠 Artificial Intelligence - superfast on-device vector search.
🏁 High performance on restricted devices, like IoT gateways, micro controllers, ECUs etc.
💚 Resourceful with minimal CPU, power and Memory usage for maximum flexibility and sustainability
🔗 Relations: object links / relationships are built-in
💻 Multiplatform: Linux, Windows, Android, iOS, macOS

🌱 Scalable: handling millions of objects resource-efficiently with ease
💐 Queries: filter data as needed, even across relations
🦮 Statically typed: compile time checks & optimizations
📃 Automatic schema migrations: no update scripts needed

And much more than just data persistence
👥 ObjectBox Sync: keeps data in sync between devices and servers
🕒 ObjectBox TS: time series extension for time based data

Add ObjectBox to your project

ObjectBox is available as a

• CocoaPods pod
• Swift Package

See Install ObjectBox Swift for details and alternative setup options.

Example

In the Example directory, you'll find a "Notes" example app demonstrating ObjectBox's Swift API. The example comes with two apps: one for iOS and one for macOS. The iOS example is a full GUI application, whereas the macOS example runs a few operations and then exits.

Swift versions

Here's a list of ObjectBox releases, and the Swift versions they were compiled with:

This might be relevant, e.g. when using Carthage. For various reasons, we recommend using the latest version.

Changelog

For notable and important changes in new releases, read the changelog.

Development

The source code for ObjectBox's Swift binding can be found in the Source folder of this repository.

Background: code generation

ObjectBox Swift Database uses generated code for optimal performance at runtime by avoiding reflection etc.

It uses a fork of Sourcery for this.

ObjectBox is a cross-platform database supporting sustainable app development in multiple native languages:

• Flutter/Dart Database: persist Dart objects & build cross-platform apps using Flutter.
• C and C++ Database: native speed with zero copy access to objects on embedded devices
• Java/Kotlin Database: runs on Android, desktop, and servers.
• Golang Database: great for IoT, data-driven tools, and server applications. also enables porting ObjectBox to other languages.
