ObjectBox Swift

Version Platform

ObjectBox is a superfast, light-weight object persistence framework. 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<Person> = personBox.query {
    return (Person.firstName.contains("Santa") || Person.age > 100)
           && Person.lastName.isEqual(to: "Claus") 
}.build()
let oldClauses = query.find()

Want details? Read the guides or check out the API docs.

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
1.4.1 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.

How can ObjectBox Help You?

We want ObjectBox to be not only the fastest, but also the most Swift-friendly persistence solution.

To do that, we want your feedback: what do you love? What's amiss? Where do you struggle in everyday app development?

We're looking forward to receiving your comments and requests:

Thank you!

Background: code generation

ObjectBox Swift 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).
