Unity iOS TestFlight Upload Error Fix - Asset validation failed (90206) Invalid Bundle

Error Analysis

• When attempting to upload to TestFlight using Transporter, the following error occurred:

Asset validation failed (90206)
Invalid Bundle. The bundle at 'TOYVERSE.app/Frameworks/UnityFramework.framework' contains disallowed file 'Frameworks'.(ID: 54a900bb-b251-492a-bed7-ee556a02d857)

• Traces of disaster…

Solution

• Checked StackOverflow thread
• Go to the xcworkspace of the Xcode project built from Unity.
• Search for embed in Build Settings for both Unity-iPhone app and UnityFramework.
• You will see Always Embed Swift Standard Libraries. If this is set to Yes, the upload is highly likely to fail.

• Therefore, disable these two in the Unity build script PostProcessBuild via post-processing.

...
foreach (var targetGuid in new[] { mainTargetGuid, project.GetUnityFrameworkTargetGuid() })
{
  project.SetBuildProperty(targetGuid, "ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES", "No");

  project.SetBuildProperty(targetGuid, "LD_RUNPATH_SEARCH_PATHS", "$(inherited) /usr/lib/swift @executable_path/Frameworks");
  //project.AddBuildProperty(targetGuid, "LD_RUNPATH_SEARCH_PATHS", "/usr/lib/swift");
}

project.SetBuildProperty(mainTargetGuid, "ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES", "No");
...

• Build again and upload, and it succeeds!
