How to Add Custom Build Properties in Unity for Desktop Projects

When working with Unity, particularly if you're targeting different platforms, you may find yourself needing to customize build properties. While it’s straightforward to add build flags for iOS builds using Unity’s post-processing tools, the process can be less clear for Mac desktop projects. So, how can you effectively add an OTHER_CODE_SIGN_FLAGS or similar build properties for OSX builds in Unity? Let’s delve into the solution!

The Problem at Hand

Unity provides an efficient way to configure iOS builds through a specialized setup known as PBXProject. Using this, developers can easily append build flags and make other modifications that streamline the build process. However, when it comes to Mac desktop builds, you might notice that there’s no equivalent StandaloneProject structure available. This leads to a frustrating scenario where you may still have to manually tweak your Xcode project every time you create a build, defeating the purpose of automation.

The Limitation

No StandaloneProject: There isn't a dedicated structure in Unity for desktop builds like there is for iOS.

Manual Work: You might end up configuring build properties by hand each time you generate your project.

The Solution

Fortunately, there’s a workaround for this challenge. By utilizing Unity's build post processing capabilities, you can automate the inclusion of additional build properties into your OSX project. Here’s how you can do it:

Step-by-Step Guide

Create a Custom Post-Processor Script

You need to create a script that will act as a post-processor for your build. Here’s the complete code you would use:

Understand the Code

File Paths: The script specifies the path to the project file (project.pbxproj).

File Reading/Writing: It reads the content of this file, allows you to inject the necessary build property (OTHER_CODE_SIGN_FLAGS), and then rewrites the modified content back to the file.

Log Output: It also provides feedback in the console log to confirm the action.

Adaptation for Other Properties

You can modify the string replacement code to add any other build properties where needed. This allows for great flexibility as your project's needs evolve.

Final Thoughts

While adding build properties to OSX builds in Unity may not have a straightforward approach directly within the Unity interface, utilizing a custom post-processor script effectively bridges that gap. With this method, not only do you automate your build processes, but you also save yourself from the repetitive chore of manual adjustments each time you compile your project.

By implementing these small yet powerful changes, you can maintain a streamlined workflow in Unity when targeting desktop platforms, just as you do for mobile.



Now you can effortlessly customize your Mac desktop builds with build properties, making your development process in Unity much more efficient!
