On macOS, .bundle plugins are broken when using Xcode to generate standalone build

Unity: MacOS

2023.1.X

2022.2.X

Fix an issue with Mac standalone builds where the generated Xcode project did reference .bundle plugins as a single plugin

Verified on 2022.2.12f1 on local machine. Bundle plugin is present after xcode build.

Builds with .bundle plugins in Xcode fail as of 2022.2 when building an exported Xcode project with MacStandalone as the target

Repro:

1) Create a project. Add a .bundle plugin.

2) Build for mac. Make sure the Xcode project generation box is checked.

3) Open project in Xcode and build

Result:

Build fails. The project doesn't have the bundle. Instead it has all of the bundle contents.

Expected:

Succeeds. Only the bundle should be tracked, not its contents.
