Uploading SPI error: Validation failed (409) The app contains one or more corrupted binaries. Rebuild the app and resubmit. NSUnderlyingError : Validation failed (-19241) The app contains one or more corrupted binaries. Rebuild the app and resubmit

I am using Xcode (Version 26.2 (17C52)) -> Archive -> Distribute App (or Validate App) to upload my iOS app into App Store Connect.

However I am always getting this error:

I tried exporting the app as an IPA and uploading with Transporter, but I see the same error.

I couldn't find any other useful logs or error messages.

REPRODUCTION STEPS:

1. Archive complete iOS app using Xcode 26.2

2. Upload to App Store Connect (upload succeeds)

3. Apple's automated SPI analysis runs

4. Validation fails with "corrupted binary" error

TECHNICAL DETAILS:

1. Target: iOS 15+
2. Xcode: 26.2
3. Architecture: arm64

I have created the app in App Store Connect and this is my first time uploading. The app can build and run on my physical phone and emulator without any problem. Would be great to get some help! Thanks!
