Xcode Cloud Export Archive Fails with Xcode 26.2 RC

Export archive step fails in Xcode Cloud when using Xcode 26.2 (17C48) RC.

• The same project exports successfully when switching back to Xcode 26.1 in Xcode Cloud workflow settings.
• The same project exports successfully when using Xcode 26.2 RC locally.
• Projects without Apple Watch app do not encounter this issue (not so sure about this).

From Xcode Cloud UI:

Exporting for App Store Distribution failed. Please download the logs artifact for more information.

Run command: 'xcodebuild -exportArchive ...
Command exited with non-zero exit-code: 70

From xcodebuild-export-archive.log:

Workaround

• Switching Xcode Cloud workflow to use Xcode 26.1 works around the issue.
• Using Xcode 26.2 RC locally works around the issue.
