How do I trust a swift macro target for Xcode Cloud builds?

I just added my first Xcode 15, Swift 5.9 macro from an open source package that I'm referencing via Swift Package Manager. The first time I compiled locally, I had to trust the macro's package via a dialog box, which is fine for a local build. However, now my app doesn't build on Xcode Cloud, with the error "Target must be enabled before it can be used."

How do I tell Xcode Cloud to trust the macro's target?

The suggestion provided by slavikus does work, but it poses a security risk because it enables any macro, allowing for the inclusion of malicious code in your Xcode build.

A safer approach could be to inform Xcode Cloud about the Macros you have explicitly enabled in your project, which are stored at ~/Library/org.swift.swiftpm/security/macros.json, by creating a post-clone script that copies this file into an internal location within Xcode Cloud.

Here are the steps to implement this solution:

1. Create a folder called ci_scripts in your project's root directory.
2. In this folder, create a script named ci_post_clone.sh with the following content:

#!/bin/zsh 

mkdir -p ~/Library/org.swift.swiftpm/security/
cp macros.json ~/Library/org.swift.swiftpm/security/

3. Copy file ~/Library/org.swift.swiftpm/security/macros.json into the same folder.

This script will be executed after your project is cloned from the repo and before Xcode Cloud starts building the project.
