Xcode Cloud can't build projects that uses Composable Architecture v1.4.0

[darrarski]

Description

After updating an Xcode project to use Composable Architecture v1.4.0, Xcode Cloud can no longer build it. CI fails with the following errors:

Target 'CasePathsMacros' must be enabled before it can be used.

Target 'ComposableArchitectureMacros' must be enabled before it can be used.

The project does not use any of the newly introduced macros. It builds fine with Xcode Cloud when using previous releases of Composable Architecture.

I'm aware that third-party macros should be enabled in Xcode before use. I'm unsure how to set it up to work when using Xcode Cloud.

Checklist

• I have determined whether this bug is also reproducible in a vanilla SwiftUI project.
• If possible, I've reproduced the issue using the main branch of this package.
• This issue hasn't been addressed in an existing GitHub issue or discussion.

Expected behavior

Xcode Cloud can build a project that depends on Composable Architecture

Steps to reproduce

1. Create a new Xcode project.
2. Add Composable Architecture dependency (make sure you use v1.4.0).
3. Setup Xcode Cloud.
4. Run Xcode Cloud build.

@darrarski This is a general new step required by macros. A quick web search led me to this page with a few ways of addressing the error:

https://forums.swift.org/t/is-there-a-way-to-programmatically-allow-trust-the-compiler-plugin-to-run-from-the-command-line/65690

Command line default you can set:

defaults write com.apple.dt.Xcode IDESkipMacroFingerprintValidation -bool

Argument you can pass to xcodebuild

-skipMacroValidation

Since this isn't a bug I'm going to convert it to a discussion.

Thanks for the feedback! Adding the following line to ci_scripts/ci_post_clone.sh solves the problem:

defaults write com.apple.dt.Xcode IDESkipMacroFingerprintValidation -bool YES
