We are encountering a build and archive failure in Xcode after updating our development machine to macOS 26.2.

Environment:

macOS: 26.2
Xcode: 16.2
iOS Deployment Target / Runtime: iOS 18.5
App Type: Production iOS app (App Store distribution)

Issue: Before updating macOS, the project built and archived successfully. After the macOS 26.2 update, archiving fails consistently, even though no major changes were made to the project code or configuration.

Certificates, provisioning profiles, and signing settings are correctly configured. The issue appears to be related to the macOS/Xcode environment rather than application logic.

Steps to Reproduce:

Open the existing iOS project in Xcode 16.2.
Select the App Store distribution scheme.
Attempt to Archive the project.
Archive/build fails.

Expected Result: Successful archive allowing upload to App Store Connect.

Actual Result: Archive fails after macOS 26.2 update.

Thanks for this, I would recommend to get the error message from the build report itself.

Follow the steps below to collect the full build report in Xcode:

Choose View > Navigators > Reports.
Select the report associated with your app’s build in the navigator.
Using the filter bar at the top of the build report, select the filter buttons for All and All Messages.
Click Export in the filter bar to save the detailed build report.

Please share the error message here if you want.

Additional information about collecting a build report is available in Xcode’s documentation: https://help.apple.com/xcode/mac/current/index.html?localePath=en.lproj#/dev1c8beb00d

Hope this helps
