Description
ObjectBox is a superfast, light-weight object persistence framework (aka a database). This Swift API seamlessly persists objects on-device for iOS and macOS.
let santa = Person(firstName: "Santa", lastName: "Claus")
try personBox.put(santa)
let query: Query = personBox.query {
return (Person.firstName.contains("Santa") || Person.age > 100)
&& Person.lastName.isEqual(to: "Claus")
}.build()
let oldClauses = query.find()

Swift Database - swiftly persist objects on iOS and macOS
Your opinion matters to us! Please fill in this 2-minute Anonymous Feedback Form.
ObjectBox is a superfast, light-weight Swift database persisting Swift objects fast, easily, and fully ACID-compliant on-device on iOS and macOS. On top, it comes with an out-of-the-box Data Sync handling the complexity of occassionally connected devices, networking and conflict resolution code for you. Build apps that reliably sync between devices and any backend, offline on-premise or online with the Cloud.
let santa = Person(firstName: "Santa", lastName: "Claus")
try personBox.put(santa)
let query: Query<Person> = personBox.query {
return (Person.firstName.contains("Santa") || Person.age > 100)
&& Person.lastName.isEqual(to: "Claus")
}.build()
let oldClauses = query.find()

Features
๐ High performance on restricted devices, like IoT gateways, micro controllers, ECUs etc.\ ๐ช Resourceful with minimal CPU, power and Memory usage for maximum flexibility and sustainability\ ๐ Relations: object links / relationships are built-in\ ๐ป Multiplatform: Linux, Windows, Android, iOS, macOS
๐ฑ Scalable: handling millions of objects resource-efficiently with ease\ ๐ Queries: filter data as needed, even across relations\ ๐ฆฎ Statically typed: compile time checks & optimizations\ ๐ Automatic schema migrations: no update scripts needed
And much more than just data persistence\ ๐ฅ ObjectBox Sync: keeps data in sync between devices and servers\ ๐ ObjectBox TS: time series extension for time based data

Adding ObjectBox to your project
CocoaPods is recommended to set up ObjectBox in your project.
See the installation docs for alternative setups,
or the New to CocoaPods? section below for a quick intro.
To install the ObjectBox
pod, add the following line to your Podfile:
pod 'ObjectBox'
Then run this to install the ObjectBox framework:
cd /path/to/your/project/folder/ # whatever folder your Podfile is in.
pod install
Pods/ObjectBox/setup.rb myproject.xcodeproj # whatever your Xcode project is named
And, don't forget to close the Xcode project (.xcodeproj) and open the workspace (.xcworkspace) instead. Now, you are all set to define your first ObjectBox entities; e.g. check the getting started guide or the example described below.
New to CocoaPods?
CocoaPods is a dependency manager and sets up libraries like ObjectBox in your Xcode project. To install it, run this in a terminal:
sudo gem install cocoapods
In CocoaPods, you keep track of used libraries in a file called "Podfile". If you don't have this file yet, navigate to your Xcode project folder and use CocoaPods to create one:
pod init
CocoaPods troubleshooting
If pod install
fails, try updating CocoaPods first:
gem update xcodeproj && gem update cocoapods && pod repo update
Swift versions
Here's a list of ObjectBox releases, and the Swift versions they were compiled with:
ObjectBox version(s) | Swift version |
---|---|
1.5.0 | 5.3(.2) |
1.4.1 | 5.3 |
1.3, 1.4.0 | 5.2 |
1.2 | 5.1 |
This might be relevant, e.g. when using Carthage. For various reasons, we recommend using the latest version.
Example
In the [Example](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.
To setup the example, use CocoaPods to acquire the framework:
cd Example/
pod install # if that fails, update CocoaPods (see Installation)
Pods/ObjectBox/setup.rb
This will generate a NotesExample.xcworkspace
that you can launch to try out ObjectBox.
Background: code generation
ObjectBox Swift Database generates code at build time for optimal performance at runtime by avoiding reflection etc. This is automatically done for you and should be transparent. Internally, we use a fork of Sourcery for this.
Source code
Source code for ObjectBox's Swift binding can be found [in the Source folder](Source/README.md).
Already using ObjectBox?
We're on a mission to bring joy and delight to Mobile app developers. We want ObjectBox not only to be the fastest Swift database, but also the swiftiest Swift data persistence, making you enjoy coding with ObjectBox.
To do that, we want your feedback: what do you love? What's amiss? Where do you struggle in everyday app development?

Cross-platform database: Mobile, Desktop, Browser, Embedded, IoT
ObjectBox is a cross-platform database supporting multiple native languages:
- ObjectBox Java/Kotlin Database: runs on Android, desktop, and servers.
- Golang Data Persistence: great for IoT, data-driven tools, and server applications.
- C and C++ Database: native speed with zero copy access to objects on embedded devices also enables porting ObjectBox to other languages.
- Flutter/Dart Database: persist Dart objects & build cross-platform apps using Flutter.
