Steps to Reproduce

1. Use version 7.12.0
2. Build RN in release mode
3. Build failure with ❌ error: Cycle inside X; building could produce unreliable results.

v7.11.0 is working well, I don't have much info except I'm building with eas locally (command line example: eas build --profile preview --platform ios --non-interactive --local --clear-cache --output builds/x.ipa

Expected Result

No regression on build with v7.12.0

Actual Result

Build failure with 7.12.0 ❌ error: Cycle inside X; building could produce unreliable results.

Hello @huextrat and thanks for reporting!
We will make sure to take a look at this issue soon and come back to you.

In the meantime, could you please confirm whether this issue is reproducible only when you build your app with eas build? And building in development mode works as expected, right?

Hi @alwx,

Yes, it's during build with eas build (building with Xcode directly in release mode give the same issue), the script phase "Upload debug symbols to Sentry" seems to be the cause of the issue.

Development (debug) mode is working with no issue as this script phase is not used 👍

I've experienced the same issue trying to upgrade v7.10.0 to v7.12.0. I had to revert to 7.10.0

Same issue, building in Xcode locally (which calls eas under the hood)

It's an issue with version 7.12.0, possibly 7.11.0 too, 7.10.0 works properly.
