The setup.rb Script
ObjectBox uses a Swift code generator to generate boilerplate code that passes object information to the library. Therefore, you can simply enjoy plain Swift objects.
ObjectBox brings its own code generator (based on Sourcery
) to generate boilerplate code that passes information about your objects to the library. Code generation avoids inheritance trees and runtime reflection so you can write plain Swift objects that can be persisted extremly fast.
setup.rbscript does the following things to ensure the code generator is run transparently whenever you build your project:
In your Xcode project, add a "New Run Script Phase" and make sure it comes above the Compile Sources phase of your project. The code generator needs to generate the code you want to compile first.
We call the Build Phase "[OBX] Update Sourcery Generated Files".
Enter the following script into this build phase:
The above example assumes you've extracted the files from the ObjectBox release on Github into a folder named
ObjectBoxnext to your project. If you had a folder named
externalfor all external dependencies next to a
myprojectfolder that contains your project, that line might read:
You get the picture. In general, it is a good idea to use project-relative paths, so anyone checking out your project can run it, no matter where they keep their checkouts, or what their username.
Build your project once, so it can create the
generated/EntityInfo.generated.swiftfile for you. It will not contain much of interest, yet, but now that the
generated/directory and its contents exist, you can drag them into your Xcode project so they get compiled as well (make sure you add folders as "groups", not as "folder references").
You now have a working ObjectBox setup in your project and should be able to follow the rest of the instructions in our Getting Started section.
