Mockingbird doesn't support Xcode 16's new PBXFileSystemSynchronizedRootGroup's

[rivera-ernesto]

New Issue Checklist

• I updated the framework and generator to the latest version
• I searched the existing GitHub issues and list of common problems

Overview

Xcode 16 now allows you to create Folders instead of Groups

This new folders (PBXFileSystemSynchronizedRootGroups) are meant to simplify keeping all contained items into the parent's target among other things, but they are not supported by Mockingbird which throws this error:

Using Mockingbird v0.20.0
Error: The element PBXFileSystemSynchronizedRootGroup is not supported.
Command PhaseScriptExecution failed with a nonzero exit code

Environment

• Mockingbird CLI version 0.20.0
• Xcode and Swift version swift-driver version: 1.115.1 Apple Swift version 6.0.3 (swiftlang-6.0.3.1.10 clang-1600.0.30.1) Target: arm64-apple-macosx15.0
• Package manager CocoaPods
• Unit testing framework XCTest
• Custom configuration
  • Mockingbird ignore files
  • Supporting source files

It happened me something similar. After Mockingbird is downloaded, it shows this error:

PBXFileSystemSynchronizedBuildFileExceptionSet is not supported

I'm following the Mockingbird SPM tutorial.

Same issue here.
The solution on our side was to remove all the folders from the project and use only groups.
Too bad that this great framework is not updated any more, the last release (tag) is from 2022.
I consider 3 years old libraries outdated.
