ITMS-90714: Invalid binary error when uploading a Mac Catalyst app using Xcode 26.1

[SwissTemp]

Hi. Since the Xcode 26.1 update yesterday, I'm receiving a "ITMS-90714: Invalid binary - The app contains one or more corrupted binaries. Please rebuild the app and resubmit." error when uploading the binary of my app to App Store Connect. After hours I finally managed to narrow it down to the swift-collections package (specifically DequeModule). As soon as this package is added, the error shows up. But: This is only when building for Mac Catalyst. When building for iOS or tvOS everything is fine.

Information

• Package version: 1.3.0
• Platform version: 26.1
• Swift version: swift-driver version: 1.127.14.1 Apple Swift version 6.2.1 (swiftlang-6.2.1.4.8 clang-1700.4.4.1) Target: arm64-apple-macosx26.0

Checklist

• If possible, I've reproduced the issue using the main branch of this package.
• I've searched for existing GitHub issues.

Steps to Reproduce

Open Xcode 26.1. Create project targetting Mac Catalyst 15.0. Add swift-collections package. Upload app to App Store Connect. Wait for completion of binary processing.

Expected behavior

Successful processing of the binary

Actual behavior

Receiving email with "ITMS-90714: Invalid binary - The app contains one or more corrupted binaries. Please rebuild the app and resubmit." error.
