Since last week I get this error when uploading my app to app store Connect:

Unsupported SDK or Xcode version. Your app was built with an SDK or version of Xcode that isn’t supported. Although you can use beta versions of SDKs and Xcode to build and upload apps to App Store Connect, you need to use the latest Release Candidates (RC) for SDKs and Xcode to submit the app. For details on currently supported SDKs and versions of Xcode, visit: https://developer.apple.com/news/releases. (ID: 18be8ca4-805d-4cc2-9b3d-3c7a97a89c7b)

I could upload before. I have the Tahoe Beta 26.0 iOS installed and the xcode 26.0 beta 4. Does anyone has advise on how to solve this issue?

You cannot upload with a beta version. That's exactly what the message was telling you.

PS:Thanks for reporting it's solved. But would even be better to tell how.
